Fisherr EU 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.

September 2014

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 Trimt III (figure 5) and WhisperFlot cages are available. To eliminate liquid cavitation damage, Cavitrolt III 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.

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.
