Fisherr EU and EW Valves

NPS 12 through 24 x 20
The Fisher NPS 12 through 24 ! 20 CL150 through
CL600 EUT-2, EWT-2, EUD, EWD, EUT, and EWT
control valves (figures 1, 2, and 3) 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-2 and EWT-2 valves with a hanging cage

(figure 2) 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 3) 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. Bore
Seal trim is used to obtain Class V shutoff above
316_C (600_F).

EUT and EWT valves (figure 5) have a bolted-in seat

ring. These valves have metal-to-metal seating and W9156-1

use PEEK anti-extrusion rings to obtain Figure 1. Fisher NPS 24 x 20 EWT Valve with Piston Actuator
temperatures up to 316_C (600_F).
and FIELDVUEt DVC6020 Digital Valve Controller

To help reduce aerodynamic noise in gas service,

These valves share the following characteristics: Whisper Trimt III (figure 4) and WhisperFlot cages
multiple trim material choices, trim part are available. To eliminate liquid cavitation damage,
interchangeability, and different cage styles to Cavitrol t III cages are available. For cavitating
provide particular flow characteristics to handle liquids with particulate, DST (dirty service trim) is
specific applications. available.
