Features

• Compact in Size—Small envelope because of the

built-in pilot and internal registration.

• Unique No Bleed Monitor System—Flexible

worker/monitor system setup that allows for

bleed to be piped to the intermediate piping thus

eliminating downstream bleed which reduces lost

and unaccounted for gas. Another advantage of this

conguration is that the system lockup pressure is

that of the worker instead of the monitor.

• Not an Adaptation of Existing Regulators—

New design of integrated cases and internal

registration ports.

• Wide Variety of Applications—Natural gas

distribution systems, gas supply to industrial

boilers, furnaces, ovens, mixers, plant air service.

• Highest Quality— Designed and manufactured to

ISO 9001 standards.

• Accuracy—Keeps constant inlet pressures to

downstream equipment by accurately controlling

distribution system pressures at widely varying ow

rates and supply pressures for maximum efciency

and best operation or by eliminating the need for

pressure-compensating meters by holding a steady

pressure to the meter inlet.

• Optional Token Relief—The Types 299HR and

299HSR with an integral token relief in the pilot is

designed to relieve minor overpressure caused by

thermal expansion.

• High-Capacity Pressure Control—Actuator

diaphragm responds quickly to downstream

pressure change, causing immediate correction in

main valve position. Pilot responds simultaneously

and controls nal positioning of main valve. This

action permits full main valve travel, resulting in

higher capacity than could be obtained without an

external pilot regulator.

• Easy Registration Conversion—Two screws and

O-rings change internal registration to external or

dual registration.

• Easy Startup—No special procedure required.

• Easy to Maintain—Main valve disk and orice can

be inspected without removing body from pipeline.

Easy access two bolt ange permits quick removal

of actuator and pilot from body.

• Economical, Labor-Saving Installation—Supply

pressure to pilot is factory-piped directly from inlet

side of main regulator body, thus requiring no

upstream pilot supply line on standard installations.

• Rugged Construction—With a two bolt connection

of the regulator to the body and no union ring, the

299H Series regulators are designed for longer

service life with minimal maintenance requirements.

• No gaskets—Reusable O-rings at all

serviceable joints.

• Startup Protection—The main valve and the pilot

are designed with reverse pressure mechanisms to

prevent damage during startup or sudden increase

in downstream pressure.

• Fewer Parts—Fewer recommended parts needed

for spare parts inventory.

Introduction

Description

!

WARNING

Since a pilot-operated regulator is

constructed of both a pilot and a main

valve, do not exceed the maximum inlet

pressure shown on the nameplate.

The 299H Series pressure reducing regulators provide

a broad capacity of controlled pressure ranges and

capacities in a wide variety of distribution, industrial

and commercial applications. A 299H Series regulator

has a pilot integrally mounted to the actuator casing.

The 299H Series regulators can handle inlet pressures

up to 175 psig / 12.1 bar depending on orice size.

The integral token relief on the Types 299HR and

299HSR regulators is located in the pilot and

alerts you to an increase in downstream pressure

beyond the regulator setpoint.

The Type 299HS provides overpressure or

overpressure and underpressure protection by

completely shutting off the ow of gas to the

downstream system. It comes with a Type VSX-2

slam-shut device which can be congured for

Ovepressure Shutoff (OPSO) or Overpressure and

Underpressure Shutoff (OPSO/UPSO). The slam-shut

device’s actions are independent of the main valve

and of variations to the inlet pressure. The Type VSX-2

slam-shut device has internal or external registration.

External registration requires a downstream

sensing line.

Options

P590 Series Pilot Supply Filter

The optional P590 Series pilot supply lter prevents

pipeline debris from entering the pilot; a primary cause

of pilot clogging. When the upstream system is free of

debris, the 299H Series regulators may be installed

without a pilot supply lter.

Type 67CF Filtered Pilot Supply Regulator

When it is necessary to install a pilot supply regulator,

an optional Type 67CF ltered pilot supply regulator

may be installed. For example, on applications with

inches of water column setpoints and inlet pressure

variations of more than ±20 psig / ±1.4 bar it may

be necessary to install a Type 67CF to maintain

published accuracy.

Principle of Operation

Letter keys in this section refer to Figure 3 unless

otherwise noted. Fast response and accuracy are made

possible by the amplifying effect of the pilot and by the

two-path control system. The function of the pilot is

to sense change in the controlled outlet pressure and

amplify it into a larger change in the loading pressure.

Any changes in outlet pressure act quickly on both the

actuator diaphragm and the loading pilot, thus providing

the precise pressure control and fast speed of response

that is characteristic of a two-path system.

Upstream or inlet pressure is utilized as the operating

medium, which is reduced through pilot operation to

load the main diaphragm chamber. Tubing connects

the inlet pressure to the pilot. Downstream or outlet

pressure registers underneath main diaphragm (E) and

on top of pilot diaphragm (F). There are three different

versions of pressure registration for the Type 299H.

Internal registration (screws and O-rings (J)

removed)—Outlet pressure is registered through the

throat to the main diaphragm chamber and through a

small port (G) to the top of the pilot diaphragm. Internal

registration is used for ease of installation. Capacity

is somewhat limited because of droop and/or boost

associated with sensing pressure within the body.

External registration—Screws and O-rings (J) block

the throat and a downstream control line is connected to

the pilot diaphragm chamber which is connected to the

lower main diaphragm chamber by a small port (G). The

other end of the control line connects to the downstream

pipeline. External registration is used for higher capacity

and/or the upstream regulator in a monitor set. It also

allows monitoring for inlet pressures over 66 psig /

4.5 bar. Capacity is increased because of better

registration of pipeline pressure when a control line is

used. The alternate 3/4 NPT control line connection

(on the side of the pilot) can be used for piping

convenience, see Figures 8 and 9.

Dual registration (screws and O-rings (J) removed)—

The lower main diaphragm chamber registers outlet

pressure through the throat and the pilot diaphragm

chamber registers downstream pressure by use of

a downstream control line. The port (G) between the

chambers is blocked by inserting a screw and O-ring

(J) that was removed from the throat and the control

line runs from the pilot to the downstream pipeline. Dual

registration, with its larger orice (control line must be

piped to the primary 3/4 NPT connection on the side

of the pilot), provides an improved performance as

compared to internal pressure registration when used in

low ow rate and high pressure drop applications. It is

also used for no downstream bleed monitoring systems

with inlet pressures up to 66 psig / 45 bar.

Type 299H

In operation, assume the outlet pressure is less than

the setting of pilot control spring (A). The top side

of pilot diaphragm assembly (F) will have a lower

pressure than the setting of spring (A). Spring (A)

forces the diaphragm assembly upward, opening the

pilot orice (C). Additional loading pressure is supplied

to the top side of the main diaphragm (E).

This creates a higher pressure on the top side of

main diaphragm (E) than on the bottom side, forcing

the diaphragm downward. This motion is transmitted

through a lever, which pulls the valve disk (K) open,

allowing more gas to ow through the valve.

When the gas demand in the downstream system

has been satised, the outlet pressure increases.

The increased pressure is transmitted through the

downstream control line (for external or dual registration)

or through the port (G) (for internal registration) and acts

on top of the pilot diaphragm (F). This pressure exceeds

the pilot spring setting and forces the diaphragm down,

closing the orice (C). The loading pressure acting on

main diaphragm (E) bleeds to the downstream system

through a bleed restriction (H).

With a decrease in loading pressure on top of main

diaphragm (E), main spring (B) exerts an upward

force on the diaphragm post connected to main

diaphragm (E), pulling it upward. This moves the

main valve disk (K) toward its seat, decreasing ow

to the downstream system.

Type 299HR

Refer to Figure 4. The Type 299HR provides an integral

token relief valve. During an overpressure condition the

spring on the pilot post will allow the diaphragm head to

travel to the spring case. As the diaphragm head moves

a small amount of gas is relieved.

Note

The Type 299HR is not a full capacity

relief device. Approximate start-to-

discharge pressure is dependent on set

pressure, see Figure 7.

During normal operation the Type 299HR performance

is identical to the Type 299H. If an overpressure

condition occurs, the pilot diaphragm head will

separate from the pilot diaphragm post and travel

until it contacts the pilot spring case. The movement

of the diaphragm head creates a path and a token or

noticeable amount of gas will be released.

When the overpressure condition ceases, the pilot

diaphragm head will return to the diaphragm post and

the regulator will return to normal operation.

Type 299HS

Refer to Figure 5. The Type VSX-2 slam-shut device

on the Type 299HS regulator is a fast acting slam-shut

valve which provides overpressure or overpressure

and underpressure protection by completely shutting

off the ow of gas to the downstream system. The

slam-shut module’s actions are independent of the

Type 299HS main regulator and of variations to

the inlet pressure. The Type VSX-2 has internal or

external registration. External registration requires a

downstream sensing line.

The slam-shut disk is held in the open position (reset

position) by a small ball holding the disk stem. If the

pressure below the diaphragm increases (or decreases)

reaching the Type VSX-2 setpoint, the diaphragm will

travel upwards (or downwards) operating a lever which

in turn releases the ball.

Once the ball is released, the spring force on the stem

will push the stem and disk to the closed position against

the seat shutting off all gas ow. The pilot supply pressure

is also shut off when the Type VSX-2 is closed. The

manual reset has an internal bypass to equalize the reset

pressure on either side on the slam-shut disk.

In order for the Underpressure Shutoff (UPSO) of

any slam shut to be triggered, the downstream pipe

pressure must drop below the UPSO setpoint. In the

case of a downstream line break, numerous factors

can prevent the downstream pipe pressure from

decreasing below the slam-shut UPSO setpoint. These

factors include the distance of pipe to the break, the

diameter of the pipe, size of the break and the number

of restrictions, such as valves, elbows and bends,

downstream of the regulator and/or slam-shut device.

Due to these factors additional protections should be

installed to stop ow in the event of a line break.

Overpressure Protection

Like most regulators, the Type 299H has outlet pressure

ratings lower than the inlet pressure ratings. Complete

downstream overpressure protection is needed if the

actual inlet pressure exceeds the outlet pressure rating.

Overpressure protection for internal parts is built

into the main and pilot diaphragms by means of a

small spring on each post. The springs will allow

the diaphragm heads to move farther on the posts

avoiding damage to or bending of the valve trim.

Overpressuring any portion of a regulator or

associated equipment may cause leakage, parts

damage or personal injury due to bursting of pressure-

containing parts or explosion of accumulated gas.

Regulator operation within ratings specied in the

Specications section and on the regulator nameplate

does not preclude the possibility of damage from

external sources or from debris in the pipeline. A

regulator should be inspected for damage periodically

and after any overpressure condition. The pilot vent

is provided with a 1/4 NPT tapped connection in the

spring case.

Monitoring Systems

Monitoring regulators serve as overpressure protection

devices to limit system pressure in the event of open

failure of a working regulator feeding the system.

1. Low Pressure Trip cannot be used with this main valve spring range for an internally registered Type VSX-2 to provide underpressure shutoff under owing conditions. If protection against

loss of inlet pressure is the only required function for the Type VSX-2 then an internally registered Type VSX-2 may be used with the same minimum trip pressures as an externally

registered Type VSX-2.

2. 70% of regulator setpoint is the minimum allowable Low Pressure Trip setting for an internally registered Type VSX-2 used with this main valve spring range. If protection against loss of inlet

pressure is the only required function for the Type VSX-2 then an internally registered Type VSX-2 may be used with the same minimum trip pressures as an externally registered

Type VSX-2.

3. 75% of regulator setpoint is the minimum allowable Low Pressure Trip setting for an internally registered VSX-2 used with this main valve spring range. If protection against loss of inlet

Wide-Open Monitor

The control line of the upstream regulator is connected

downstream of the second regulator (Figure 6), so

that during normal operation the monitoring regulator

is standing wide open with the reduction to distribution

pressure being taken across the working regulator. Only

in case of open failure of the working regulator does the

wide-open monitoring regulator take control at its slightly

higher setting. A pressure build-up above the monitor set

pressure is required for the monitor to take control in the

event of an overpressure situation. Installing a pilot supply

regulator on the monitor will minimize the pressure build-

up. The pilot supply regulator should be set to

3 psig / 0.21 bar above the monitor setpoint.

The minimum set pressure difference between

the worker and monitor should be greater than the

proportional band. Small set pressure differences may

cause the worker and monitor to function independently.

The upstream regulator can easily be eld converted

or ordered with screws and O-rings in the throat

(Figure 6). This seals off the path that otherwise would

let line pressure ahead of the working regulator inlet

and try to close the wide-open monitoring regulator.

No Downstream Bleed Monitor

The no bleed monitor is a wide-open upstream

monitor which works like a conventional wide-open

upstream monitor except for registration. The no bleed

monitor utilizes a dual registration construction as

opposed to the external registration construction of the

conventional monitor. This ensures that the lockup of

the monitor system is the lockup of the downstream

working monitor at zero ow during normal operation.

Installation

Although the actuator and pilot can be mounted in

90° increments relative to the body, the normal installation

is with the body in a horizontal run of pipe and the pilot

hanging vertically from the bottom of the actuator.

Control and vent lines necessary for installation are not

supplied with a Type 299H regulator. Control and vent

connection locations are shown in Figures 8 and 9.

In many instances good piping practice will require

that outlet piping be swaged up above the body size

to prevent excessive pressure drop along the outlet

line. The piping should be expanded as close to the

regulator outlet as possible.

Capacity Information

Tables 5 through 10 give the 299H Series natural gas

regulating capacities at selected inlet pressures and

outlet pressure settings. Flows are in SCFH (60°F and

14.7 psig) and Nm³/h (0°C and 1.01325 bar) of 0.6

specic gravity natural gas. To determine equivalent

capacities for air, propane, butane or nitrogen, multiply

the capacity number in the tables by the following

appropriate conversion factor: 0.775 for air, 0.628 for

propane, 0.548 for butane or 0.789 for nitrogen. For

gases of other specic gravities, multiply the given

capacity by 0.775 and divide by the square root of the

appropriate specic gravity.

For critical ow:

To determine wide-open ow capacities for relief

sizing of 0.6 specic gravity natural gas at 60°F at

critical pressure drops (absolute outlet pressure equal

to approximately one-half or less than one-half of the

absolute inlet pressure), use the following formula:

Q = P1(abs)(Cg)(1.29)

For subcritical ow:

If pressure drops are lower than critical (absolute

outlet pressure greater than approximately one-half

the absolute inlet pressure), use the following formula

and convert according to the factors in the preceding

paragraph if necessary:

Q = CgP1SIN

where:

C1 = Cg/Cv (see Table 3)

Cg = Gas sizing coefcient (see Table 3)

G = Gas specic gravity (air = 1.0)

P1 = Regulator inlet pressure, psia

∆P = Pressure drop across regulator, psi

Q = Gas ow rate, SCFH

T = Absolute temperature of gas at

inlet, °Rankine

Note

Due to boost, the above formulas

cannot be used to obtain correct

regulating capacities for regulators with

internal registration.

The published capacities were obtained using inlet and

outlet piping the same size as the regulator body size.
