Oklahoma City,

Okla., USA

FEATURES AND BENEFITS

As one of the most durable resilient-seated butterﬂy valves in

the industry, Cameron’s DEMCO butterﬂy valve excels in a

variety of applications.

Cast in both wafer and tapped lug patterns in a variety of

material choices, DEMCO butterﬂy valves feature a one-piece

body for reduced weight and increased strength.

The unique stem hole design in the disc ensures the dry stem

journal, and the hard-backed seat allows ease of installation,

reliable operation and in-ﬁeld repairability without special

tools. DEMCO butterﬂy valves are available in sizes 2” to 36”

(50 mm to 900 mm).

Engineered for long-term, reduced-maintenance

performance, DEMCO butterﬂy valves are commonly

selected for a variety of applications in the following

industries:

• Chemical and petrochemical

• Agriculture

• Oil and gas drilling and production

• Food and beverage

• Water and waste water

• Cooling towers (HVAC)

• Power

• Mining and materials

• Dry bulk handling

• Marine and government

Bi-Directional Sealing

Cameron’s DEMCO butterﬂy valve provides bi-directional

sealing at full-rated pressure with identical ﬂow from either

direction.

Integral Flange Seal

An integral ﬂange seal molded into the edge of the seat

accommodates ASME weld neck, slip-on, threaded, socket

and stub end type C ﬂanges.

ASME Class 150 Rating

With a body rating of ASME Class 150 (285 psi non-shock),

the wafer body diameters are designed to self-center in the

ASME Class 150 ﬂange pattern.

Multiple Pressure Ratings

Three drop-tight pressure ratings are offered for 2” to 12” (50 mm to 300 mm) sizes. The standard shut-off pressure rating is

200 psi, but 285 and 50 psi shut-off ratings are also available. A throttling 0 psi-rated valve is available where drop-tight closure

is not required and minimal torque is desired. Both the 50 psi and throttling ratings allow for smaller actuators, which can

signiﬁcantly reduce overall installation cost in automated applications. The 14” to 36” (350 mm to 900 mm) size valves are

available in 150 and 50 psi drop-tight shut-off ratings, as well as throttling.

A. Dry Stem Journal Reduces Potential for

Leakage

The DEMCO valve’s disc is uniquely designed with a

continuous annular-raised band around the stem hole and

disc edge, which presses into the seat ﬂat at every angular

position.

The resilient seat presses back with a higher force than the

line pressure, preventing leakage to the stem. In addition,

two O-ring ribs are provided in the seat stem bore, creating a

triple stem seal. In competitive stem seal designs with boot

seats, a seal is accomplished by an interference squeezing on

the stem or an O-ring in the stem journal. The potential for

leakage behind the seat is high for this competitive design.

As the disc wipes the seat, elongation of the stem seal area

allows leakage to collect behind the seat. This condition is

reduced by the DEMCO valve’s dry stem journal and hard-

backed seat.

B. Hard-Backed Cartridge Seat

The DEMCO valve’s cartridge seat is constructed by

permanently bonding a resilient elastomer to a rigid backing

ring. In addition to superior sealing integrity, this design:

• Makes valve installation easier because no special

precautions are required for disc position. This is

especially advantageous when installing valves with

fail-closed actuators.

• Reduces high torque and premature failure caused by

elastomer distortion, as found in other non-rigid seat

designs.

• Simpliﬁes seat replacement because the seat is slip-ﬁtted

into the body with no need for special tools.

FEATURES AND BENEFITS (CONT.)

C. Positively Oriented Disc

The rectangular drive ensures the proper orientation of the

stem disc connection. In 2” to 24” (50 mm to 600 mm) size

valves, the disc is permitted to ﬂoat on the stem to center in

the valve seat. This design enhances drop-tight sealing and

prolongs service life.

D. End-of-Line Service

Lug body valves may be used in end-of-line service with

downstream piping removed. Only weld-neck or socket

ﬂanges can be used for this service. Since upstream pressure

is excluded between the ﬂange and the seat face by the

DEMCO ﬂange seal design, there is no effective force to slide

the seat downstream. DEMCO 2” to 12” (50 mm to 300

mm) lug butterﬂy valves are suitable for liquid service up to

200 psi with downstream piping removed at 150 psi for 14”

to 36” (350 mm to 900 mm) valves.

Lug body valves are recommended for isolation of pumps,

control devices or other system components, which may

need to be removed for repair or replacement. Lug valves

also are suitable for installation at points from which piping

expansion may proceed. Such valves normally are blanked

with blind ﬂanges to protect the exposed seats until new

piping is attached.

SPECIFICATIONS

STYLES AND ACCESSORIES

The DEMCO butterﬂy valve comes in a variety of styles to suit a range of applications. In addition, a variety of quality accessories

are available to further enhance its suitability to the application.

Series NE-C

Sizes 2” to 12” (50 mm to 300 mm) are available in both

wafer and lug styles. This series is a general purpose valve

with a neck length designed to provide full clearance for the

valve top over 2” of insulation on ASME Class 150 pipe

ﬂanges.

Series NE-I

Sizes 2” to 12” (50 mm to 300 mm) are suited for a range

of applications in many industries, including food and

beverage utilities and process ﬂowlines. This short neck

design is offered in a variety of body materials. The valves

are designed for installation between ASME Class 125 and

150 ﬂanges.

Series NE-D

The valves in this series can be made in sizes 2” to 12” (50

mm to 300 mm). The Series NE-D valve is a short-neck valve

with body notches to ﬁt popular, lightweight ﬂange

patterns, making it ideal for both the bulk material handling

and the transportation industries. Valves also will center in

ASME Class 125 and 150 ﬂanges.

Series NF-C

Sizes 14” to 36” (350 mm to 900 mm) are available in both

wafer and lug styles. The wafer body has two drilled locator

lugs at the top and bottom for ASME Class 150 ﬂanges.

Bronze bearings are installed on both stems for reduced

operating torque.

Series NE-I Sanitary

This series comes in sizes 2” to 12” (50 mm to 300 mm). It

is similar to the Series NE-I valve, but is exclusively designed

to meet the rigorous requirements of sanitary service in the

food and beverage industry. The body is available in bronze,

stainless steel, aluminum or electroless nickel-coated ductile

iron.

FDA-approved materials are used for all wetted parts.

Handle parts are bronze and stainless steel, permitting

caustic washdown.

Other beneﬁts:

• The DEMCO dry journal stem seal system ensures sanitary

butterﬂy valve construction.

• Drilled passageways, a design originated by the DEMCO

brand, vent the entire interior of the disc. No closed

chamber is provided for the culture of undesirable

organisms.

• Discs are produced from smooth and non-porous

investment castings. Stem bosses are reduced for

increased ﬂow.

• The mating ﬂange contacts and compresses the

projecting inner surface of the resilient seat to form a

smooth and uninterrupted ﬂow way. This positive seal

between the innermost contact of the seat and ﬂange

ensures aseptic conditions after a piping ﬂush.

Sanitary Features

Series NEI-T Teﬂon

Because of the inert, aseptic, non-stick character of Teﬂon®,

the DEMCO NEI-T Teﬂon-lined butterﬂy valve is ideal for

clean lines in food and beverage plants. The Teﬂon seat

consists of a virgin Teﬂon liner overlaid and bonded to an

elastomer EPDM cushion, which provides resilience for

sealing. The Teﬂon liner extends over the seat faces,

completely covering and sealing the resilient material from

contact with line ﬂuids.

Marine

DEMCO marine butterﬂy valves are available in the NE-C lug,

NE-I lug and wafer, and NE-D wafer styles, and conform to:

• Title 46 of the Code of Federal Regulations

• Part 56 of the US Coast Guard’s Marine Engineering

Regulations

• The American Bureau of Shipping Standard, including

tagging per MSS-SP-25 and testing per MSS-SP-67

B. Handles and Stem Extensions

There are three basic handle designs that are compatible

with any 2” to 12” (50 mm to 300 mm) valve: ten-position

locking, two-position locking and memory stop. Memory-

stop handles provide throttling, which is inﬁnitely adjustable

and can be set by a lock nut with a memory-stop setting

(adjustable open stop). Handles are available in basic trim,

corrosion-resistant trim and sanitary trim. Stem extensions

are fabricated from carbon steel parts and contained in a

tubular housing. Gaskets and O-rings seal the stem

extension at the top and bottom. These extensions are

fabricated to speciﬁed lengths.

C. Gear Operators

DEMCO weatherproof gear operators are offered with a

choice of handwheel, chainwheel or square nuts. The worm

gear has either self-locking set screws to control open and

closed positioning or an optional adjustable memory-stop

for balance return to a preset open position after closing.

GENERAL TECHNICAL INFORMATION

Pressure Rating

Three drop-tight pressure ratings are offered for DEMCO

butterﬂy valves. Normally, 200-psi shutoff is used in butterﬂy

applications. However, 285-psi shutoff is optionally available

for higher pressure applications. For smaller actuator sizing,

50-psi valves offer reduced torque.

For reduced torque, throttling valves, which do not provide

drop-tight closure, are available.

Vacuum Rating

DEMCO butterﬂy valves will seal against 10 microns of

vacuum (29.9 inHg). For reduced torque and extended seat

life, 50-psi discs are recommended for the dry service

conditions found in many vacuum applications.

End-of-Line Service

Lug body valves can be used in end-of-line service, with

downstream piping removed. Only weld neck or socket

ﬂanges can be used for this service. Since upstream pressure

is excluded between the ﬂange and the seat face by the

exclusive DEMCO ﬂange seal, there is no effective force to

slide the seat downstream. DEMCO lug butterﬂy valves are

recommended for liquid service up to 200 psi with

downstream piping removed.

Lug body valves are recommended for the isolation of

pumps, control devices or other system components that

may need to be removed for repair or replacement.

Lug valves also are suitable for installation at points from

which piping expansions may proceed. Such valves normally

are blanked with blind ﬂanges to protect the exposed seats

until new piping is attached.

Marking

Each valve is positively identiﬁed by marking and tagging per

MSS-SP-25.

Actuation

Positive latch handles, worm gear operators and automatic

actuators are available and interchangeable on the DEMCO

valve.

The DEMCO top ﬂange is dimensionally compatible with

other competitive butterﬂy valves. With the optional “utility

top” stem, the DEMCO valve interchanges directly with

competitive valves, allowing valve replacement without the

need for new actuation.

Installation and Maintenance

DEMCO butterﬂy valves are bi-directional, with identical ﬂow

way from either face. To install, simply close the valve, insert

between ﬂanges and make up with studs or capscrews. No

regular maintenance or lubrication is ever required.

Disassembly for inspection or replacement of parts is simple.

Open the valve, remove handle or actuator, remove

tangential pins, pull out the stems, and push the disc and

seat out of the body. Reassemble in reverse order, with a

small amount of general purpose non-hydrocarbon based

lubricant on the outside of stems, seat and disc ﬂats.

Steel or cast iron ﬂanges of either raised or ﬂat-faced type

are suitable for use with DEMCO butterﬂy valves. Plastic

ﬂanges are subject to damage at installation by over-

tightening the bolting and may deﬂect or cup, resulting in

ﬂange leaks. Refer proposed plastic ﬂange installations to

Cameron’s DEMCO brand quotations department for review

and recommendation.

Throttling discs with no seat interference do not provide a

stem seal. Stem O-rings are provided for this application.

Flange gaskets assist the O-rings in 2” to 12” (50 mm to

300 mm) valves, and must be used only with throttling discs.

This nomograph gives corresponding values

for the parameters of ﬂow rate, valve size,

disc angle and pressure drop of DEMCO

butterﬂy valves in 1.0 speciﬁc gravity water

service at 68° F (20° C).

The lower right-hand corner of the graph

with the heavy line border represents line

velocities below 15 ft /sec and normally is

used for valve sizing in liquid applications.

Butterﬂy valves are economical throttling

devices. Reliable throttling can be attained at

disc openings from 25 to 70 degrees.

Sample Computation for Water

Water, with speciﬁc gravity of 1.0 and ﬂow

rate of 1200 gal/min, to 6” (160 mm)

butterﬂy valve.

Required: Pressure drop at full and

75-degree disc openings. Project horizontally

from 1200 gal/min to 6” (150 mm) valve

curve. Project vertically upward to fully open

valve curve, then horizontally to read 0.35

psi pressure drop. Continue upward

projection to intersect 75-degree opening

curve, then horizontally to read 0.8 psi

pressure drop.

Sample Computation for Air

Air, with density of 0.217 lb/cf, ﬂow rate of

40,000 cf/hr, to 5” (125 mm) butterﬂy valve.

Required: Pressure drop through fully open

valve. Disregarding change in gas condition

by pressure drop across valve, proceed from

40,000 cf/hr, as in liquid computation, to

read 15 psi pressure drop. Convert pressure

drop from water to air by multiplying this

value times the ratio of air-to-water

densities:

To determine pressure drop for any ﬂuid,

multiply value obtained from the nomograph

by the quotient of the ﬂuid density, in lb/cf,

divided by 62.4. Gas Liquid

CV values, given above, may be employed in the formula:

Where:

Q = gal/min of ﬂow through the valve

DP = psi pressure drop across the valve

D = density of ﬂuids in lb/cu ft

Pressure drop is computed by rearranging the formula to the

following:

Sample Computations

What is the ﬂow rate of water at ambient temperature

through a 4” (100 mm) butterﬂy valve that is 70 degrees

open when the pressure drop across the valve is 0.5 psi?

(Density of water at 68° F is 62.4 lb/cu ft.)

Q = 215.6 gal/min

What is the pressure drop across an 8” (200 mm) butterﬂy

valve that is fully open, ﬂowing 2000 gal/min of solvent with

a density of 55 lb/cu ft?

DP = 0.33 psi

Water Hammer

Water hammer is a series of shocks in a piping system

caused by rapidly stopping the ﬂow of ﬂuid in that system.

Although it is difﬁcult to measure pressure spikes caused by

water hammer shock with ordinary equipment, maximum

obtainable pressures caused by instantaneous valve closure

can be approximated by the following formula:

Pressure (max.) = interrupted velocity (fps) x 58 psi/ft/sec

In other words, pressure increases 58 psi for each ft/sec of

interrupted pipeline velocity.

A pipe carrying ﬂuid at a velocity of 15 ft/sec velocity will

have an instantaneous pressure increase of 870 psi under

rapid closure conditions.

The effects of water hammer are seen in a butterﬂy valve as

bent disc and stems, a broken body or both.

Water hammer can be reduced or eliminated by slowing

valve closure time in accordance with the following formula:

Where:

Q = ﬂow in gal/min

S = upstream pipe size in sq ft

P = pressure rating of the valve in psi

Generally, a closing time of six to eight seconds is sufﬁcient

to eliminate water hammer.

Cavitation Data

Liquid ﬂow is accelerated as it passes through a valve in

such a manner that pressure is decreased below the vapor

pressure and bubbles form. Immediately downstream of the

valve, velocity decreases while pressure increases and the

bubbles collapse, causing possible mechanical damage to the

valve and piping. This is called cavitation. Cavitation often

can be identiﬁed by the noise of the collapsing bubbles,

which sounds like gravel ﬂowing in the pipe.

Generally, butterﬂy valves operate with high-ﬂow capacities

and at low-pressure differentials and are not particularly

susceptible to cavitation.

When butterﬂy valves are used as control valves, one can

ensure that cavitation will not occur by applying the

following simpliﬁed formula:

DPmax = KC (P1 - PV)

Where:

DPmax = differential pressure across the valve

KC = cavitation constant

(approximately 0.35 for butterﬂy valves)

P1 = inlet pressure (psia)

PV = vapor pressure of the ﬂowing liquid (psia)

Example:

What is the maximum pressure drop possible through a

butterﬂy valve at 100 psig inlet pressure with water at

68° F (0.339 psia vapor pressure)?

DPmax = KC (P1 - PV)

Under the above conditions, it is possible to take a 40.03-psi

pressure drop across the valve before cavitation will begin.

* When line velocity exceeds 15 ft/sec, dynamic torque exceeds opening torque.

** Consult Cameron for the torque requirement of the Series NEI-T butterﬂy valve.

The torque (turning effort) required to operate a given

butterﬂy valve is determined by two factors: friction of the

disc and the seat. The interference and dynamic forces of

ﬂow through the valve tend to open or close the valve. The

actuator torque output must meet or exceed the maximum

torque requirement of the valve. Normal wet opening torque

requirements due to interference are tabulated below. Dry

service will increase opening torque signiﬁcantly. Consult

Cameron for dry service torque requirements.

The disc of a butterﬂy valve, in partially opened condition, is

subject to lift forces from passage of ﬂuid over its surfaces.

This effect is analogous to an airplane wing and results in an

unbalanced turning force on the disc. The dynamic torque is

proportional to the pressure drop through the valve and may

become signiﬁcant in some applications.

Dynamic torque typically is at a maximum when the disk

opening is about 70 degrees. Under high differential

pressure conditions, such torque may exceed the design

strength of stems, connections or actuators. The curves at

right may be used to calculate dynamic torque for DEMCO

butterﬂy valves and should be consulted in any case where

high differential pressure may occur during valve operation.

Seats vary. See pages 9, 10 and 11 for seat material description and part

number scheme for available options for different valve series.

Buna-N is a general purpose elastomer compounded for maximum

hydrocarbon or petroleum resistance.

0° F to 180° F (-18° C to 82° C). Same as Nitrile, Hycar* and NBR.

General Service EPDM is recommended for water service. Resistance to

saturated steam up to 275° F (135° C) is superior. EPDM is suitable in

alkaline solutions. EPDM is not suitable for oil or hydrocarbons.

Peroxide-cured 20° F to 275° F (-6° C to 135° C).

Food Grade EPDM is formulated in compliance with FDA guidelines

published in the Code of Federal Regulations, Title 21, paragraph

177.2600. This material is suitable for food service, except milk and

edible oils. Peroxide-cured 20° F to 275° F (-6° C to 135° C).

Sulfur-cured -30° F to 225° F (-34° C to 107° C).

Same as EPDM and Nordel*.

Black Neoprene complies with FDA guidelines and is principally

recommended for food and beverage service. It is resistant to vegetable

oils, brine and oxygen. 0° F to 180° F (-18° C to 82° C).

Same as Polychloroprene and CPE.

White Neoprene complies with FDA guidelines and offers chemical

resistance comparable to black neoprene, but it uses ﬁllers other than

carbon black to provide white coloration. Physical properties are not as

good as black neoprene, and white neoprene should be used only when

black cannot be tolerated. Storage should be under low light conditions

to prevent discoloration. 0° F to 180° F (-18° C to 82° C).

Hypalon* is compounded for chemical resistance and is superior in acids

and hydrocarbons. 0° F to 180° F (-18° C to 82° C). Same as CP.

FKM is superior at elevated temperatures and in harsh chemical

environments. FKM is not suitable for hot water or steam. 20° F to

300° F (-6° C to 149° C). Same as Fluoroelastomer.

Natural Rubber generally is superior to other elastomers in abrasion

resistance and is recommended for dry material handling. Use in oils and

solvents is not recommended. -30° F to 150° F (-34° C to 65° C).

Fluorosteam seats offer heat and chemical resistance to hydrocarbons

and hot water or saturated steam. Maximum temperature capability is

dependent on ﬂuid resistance, pressure and ﬂow rates. 20° F to 275° F

(-6° C to 135° C).

ETM-30230 is compounded to combine many of the better media

properties of Buna-N, EPDM or neoprene for service in hydrocarbons,

gasoline, solvents, animal oils and vegetable oils with a temperature

range of -30° F to 230° F (-34° C to 110° C). Abrasion resistance is equal

to Buna-N. Resistance to H2S and CO2 are superior to Buna-N. -30° F to

230° F (-34° C to 110° C).

NEI-T Teﬂon* SEAT is EPDM elastomer bonded to a virgin TFE covering.

This provides an inert, aseptic non-stick surface, which is excellent for

sanitary food service applications. 0° F to 50° F (-18° C to 10° C).

Other seat elastomers are available for special applications. Consult

Cameron.

MATERIAL SELECTION GUIDE

The following application is designed for use in determining the available material most likely to give satisfactory service and

is not meant to imply any type warranty. However, certain factors such as temperature, concentration and combinations of

chemicals may affect the ﬂuid resistance of any material. In questionable applications, testing is always the most positive way

to determine suitability. Some materials are available in certain valve sizes and series only.
