Fisherr Large ET and ED Valves

NPS 12 through 16 and NPS 30

Fisher NPS 12 through 16 and NPS 30 CL150 through

CL600 ET and ED control valves are used for either

throttling or on-off control of a wide variety of liquids

and gasses.

ET valves with a hanging cage are available for

demanding applications in oil and natural gas up to

232_C(450_ F). The hanging cage, with the seat ring

threaded into the cage, provides the valve with

easymaintenance trim. The seal between the plug and

cage and the seal between the seat ring and body are

springloaded PTFE. The springloaded PTFE seal

configuration can provide Class V shutoff per ANSI/FCI

702 and IEC 605344. The temperature range can be

extended to 316_C(600_F) for nonoxidizing service

and to 260_C(500_ F) for oxidizing service by using

the High Temperature (HTS1) seal.

ED valves utilize a hanging cage and a seat ring that is

bolted into the body. These valves have two graphite

piston rings between the cage and plug. They are used

for high temperature applications between 316_C

(600_F) and 593_C (1100_ F) with a Class IV standard

shutoff. Shutoff can be improved to Class V by using

theBoreseal.

To help reduce aerodynamicnoiseingasservice,

Whisper Trimt III and WhisperFlot cages are

available. Cavitrolt III cages are available to eliminate

the effects of liquid cavitation damage and DST, Dirty

Service Trim, is available for cavitating liquid with

particulates.

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.

Fisher NPS 24 Valve Assembly with Piston Actuator

 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.
