Fisherr ET, EAT, and ETR
Sliding-Stem Control Valves
Fisher ET, EAT, and ETR general-purpose control valves
(figures 1, 2, and 3) are used for throttling or on-off
controlofawidevarietyofliquidsandgases.Allthree
valve designs have single ports, balanced valve plugs,
and cage guiding. Metal-to-PTFE seating for stringent
shutoff requirements is standard in all valves except
those with Cavitrolt III cages. Metal-to-metal seating
forhighertemperaturesisstandardforvalveswith
Cavitrol III cages and optional for all other valves.
The temperature limits of ET valves can be extended
above 232_C(450_F) by using PEEK
(PolyEtherEtherKetone) anti-extrusion rings in
combination with a spring-loaded PTFE seal. The PEEK
anti-extrusion rings expand to close off the clearance
gapbetweentheplugandthecagewherethePTFE
seal may extrude at high temperatures and pressures.
The temperature limits are extended to 316_C (600_F)
for non-oxidizing service and to 260_C(500_F) for
oxidizing service.
Product Bulletin
51.1:ET
December 2012
The ET product line is available for a wide range of
applications, including sulfide and chloride
stress-cracking environments common to the oil and
gas production industries. To discuss available
constructions, contact your Emerson Process
Management sales office and include the applicable
codes and standards required for these environments.
The easy-et Valve Family
ET, EAT, and ETR control valves are part of the versatile
easy-e family of Fisher industrial control valves. easy-e
valves share the following characteristics:
Multiple trim material choices
Interchangeable, restricted-capacity trims and
full-sized trims to match variable process flow
demands
W1916-3
FISHER ET CONTROL VALVE
WITH 667 ACTUATOR
Different cage/plug styles that provide particular
flow characteristics for highly-specialized
applications. The standard cage comes in three
different flow characteristics:
J linear, or J equal percentage.
Whisper Trimt I, Whisper Trim III (figure 6), and
WhisperFlot cages (figures 4 and 5) attenuate
aerodynamic noise in gaseous service.
To help eliminate cavitation damage in a
properly-sized valve, a standard-travel, Cavitrol III,
one-stage cage (figure 8) and a long-travel, Cavitrol
III, two-stage cage are available in the NPS 1
throughNPS8ETcontrolvalve.

Features
Compliance with the Clean Air Act–ENVIRO-SEAL™
packing systems (figures 9 and 10) that provide an
improved stem seal to help prevent the loss of
process fluid are available. These packing systems
featurePTFEorGraphiteULFpackingwith
live-loading for reduced packing maintenance.
PTFE Seating for Long-Lasting Shutoff
Capability–Controlled compression of standard
seat construction protects PTFE disk between metal
disk seat and disk retainer (figure 1). Only the edge
of the PTFE disk is contacted by the flowstream
during normal operation. Excellent shutoff is
maintained by a backup ring or spring-loading that
forces the valve plug seal ring against the cage
(figure 1).
Valve Plug Stability– Rugged cage guiding provides
high valve plug stability, which reduces vibration
and mechanical noise.
Cost-Effective Operation and Maintenance
Economy–Increased wear resistance of hardened
stainless steel trim means longer-lasting service.
When inspection or maintenance is necessary, the
body can stay in the pipeline during removal of trim
parts. Balanced valve plug construction permits use
of smaller, lower-cost Fisher actuators. The ETR
valve also permits easy body interior access without
having to remove the bonnetoractuator(figure3).
And, trim inventory costs are cut because
dimensional standardization permits use of most
standard easy-etrimparts.
Compliance with European Standards–Valvesare
available with dimensions specified by EN/DIN
standards. See figure 15.
Sour Service Capability– Unless otherwise noted,
references are to NACE MR0175-2002. Optional
materials are available to meet NACE MR0103 and
NACE MR0175 / ISO 15156. Material requirements
under these standards vary by edition and year of
issue; the specific standard must be specified.

ENVIRO-SEAL, HIGH-SEAL
Packing Systems
ENVIRO-SEAL and HIGH-SEAL packing systems offer
exceptional sealing capabilities. These systems easily
install in existing valves or can be purchased with new
valves. These systems help seal the process to
conserve valuable process fluid. The long-life and
reliability of these systems also reduce maintenance
costs and downtime.
For applications requiring compliance with
environmental protection regulations, the unique
ENVIRO-SEAL packing system (figure 10) and a unique
ENVIRO-SEAL bellows seal system (figure 9) are
offered. The emission control packing system keeps
emission concentrations below the EPA 100 ppm
requirement.
For an excellent stem seal in applications that are not
environmentally-sensitive, the HIGH-SEAL Graphite

and 260_C(500_F) for oxidizingservice.
2. Lubricating service allows usage to 232_C(450_F)
3. Same material also used for bottom flange,if required. Restricted trim and full-sized limits are the same.

1. These in-body process temperatures assume an outside, ambienttemperature of 21_C(70_F) and no insulation onthe bonnet. When using any packing atlow process temperatures, a cast
extension bonnet may have to be used toprevent packing damage which could result fromthe formation of valvestem frost. Material selec tion for trim andother components will also be
limiting factors.
2. Temperatures above 232_C (450_F) require PEEK anti-extrusion rings andspring-loaded seal ring.

2
Donotexceedthemaximumpressure and temperature for the pressure ratingofthebodymaterialused, even though the trims shown may have higher capabilities.
3
Trim 85 may beused upto 99 bar (1440 psi) with clean dry gas. For process fluidsother than clean dry gas, use trim 85 only up to
21 bar(300 psi).

Trim 87 temperature limits can be extended to 316C(600F) for non-oxidizing service or 260C (500F) for oxidizing service if PEEK anti-extrusion rings are used
