FisherrEU and EW Valves

NPS 16 through 24 x 20

The Fisher NPS 16 through 24 ×20 CL150 through

CL600 EUT-2, EWT-2, EUD, EWD, EUT, and EWT control

valves (figures 3 and 4) are used for either throttling or

on-off control of a wide variety of liquids and gasses.

CL900 NPS 16 and 20 x 16 valves are available upon

request. Please contact your Emerson Process

Management sales office for more details. These

valves have single ports, balanced valve plugs, and

cage guiding.

EUT-2andEWT-2valveswithahangingcage(figure3)

are available for demanding applications in oil and

natural gas to 232_C(450_F). The hanging cage, with

the seat ring threaded into the cage, gives these valves

easy-maintenance trim--no trim parts are threaded

into the valve body. The seal between the plug and

cage and the seal between the seat ring and valve body

are spring-loaded PTFE seals.

EUD and EWD valves (figure 4) have a bolted-in seat

ring. These valves have metal-to-metal seating and use

two graphite piston rings between the valve plug and

cage. They are used primarily for high temperature

(over 232_C[450_F]) service. The Bore Seal is used to

obtain Class V shutoff above 316_C (600_F).

EUT and EWT valves (figure 1) have a bolted-in seat

ring. These valves have metal-to-metal seating and use

PEEK anti-extrusion rings to obtain temperatures up to

316_C(600_F).

Thesevalvessharethefollowingcharacteristics:

multiple trim material choices, trim part

interchangeability, and different cage styles to provide

particular flow characteristics to handle specific

applications.

W9156-2

To help reduce aerodynamic noise in gas service,

Whisper TrimtIII (figure 5) and WhisperFlotcages

are available. To eliminate liquid cavitation damage,

CavitroltIII cages are available. For cavitating liquids

with particulate, DST (dirty service trim) is available.

Features

Stable Control at High Pressure Drops-- Rugged

cage guiding stabilizes the valve plug at all points in

itstravelrange.Thisguidingreducesvibration,

mechanical noise, and the need for hydraulic

snubbers.

Economy-- Streamlined flow passages provide

greater capacities per initial investment than most

globe valves of the same size. Balanced valve plug

design can allow use of smaller actuators for high

pressure drops.

Cost-Effective Operation-- Increased wear

resistance of the standard hardened stainless steel

trim means long-lasting service.

Easy Maintenance-- The valve can stay in the

pipeline during removal of trim parts for inspection

or maintenance.

Bore Seal Description

TheBoreSeal(figure2)isavailablefortheEUDand

EWD only and is required for Class V shutoff

applications where the service temperature exceeds

316_C(600_F). For service temperatures below 316_C

(600_F), the EWT and EUT should be used when Class

V shutoff is required. See table 4 for availability and

temperature limits and figure 2.

TheBoreSealemploysametalCshaped seal ring that

is secured to the outside diameter of the valve plug.

When the valve plug comes into contact with the seat

ringtoclosethevalve,theBoreSealiscompressed

against the cage wall, thereby blocking a secondary

leakage path that exists between the plug and cage

wall. When the valve plug is not in contact with the

seat ring (i.e. valve open), theBoreSealisnotengaged

and the piston rings that are also secured to the

outsidediameteroftheplugassumetheroleof

blocking this secondary leakage path.
