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
control of a wide variety of liquids and gases. All three
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
for higher temperatures is standard for valves with
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
gap between the plug and the cage where the PTFE
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.
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.

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

The easy-et Valve Family

different flow characteristics: J quick-opening,
J linear, or J equal percentage.

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:



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
through NPS 8 ET control valve.



Multiple trim material choices



Interchangeable, restricted-capacity trims and
full-sized trims to match variable process flow
demands

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
feature PTFE or Graphite ULF packing with
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 bonnet or actuator (figure 3).
And, trim inventory costs are cut because
dimensional standardization permits use of most
standard easy-e trim parts.



Compliance with European Standards– Valves are
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

ULF packing system (figure 10) is offered. The
HIGH-SEAL packing system provides improved sealing
at pressure/temperature ratings beyond ENVIRO-SEAL
limits.

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.

ENVIRO-SEAL packing systems, available with PTFE,
Graphite ULF, or duplex packing, and the HIGH-SEAL
Graphite ULF packing system feature live-loading and
unique packing-ring arrangements for long-term,
consistent sealing performance.

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.

ANSI/FCI Class VI Shutoff
Capabilities
ET valves with soft seat and metal seat constructions
can provide ANSI/FCI Class VI shut-off capabilities. See
tables 3 and 4.

NOTES:
1
Use trim 27 instead of trim 29 for nonlubricating
fluids such as superheated steam or dry gases
between 149C (300F) and 232C (450F).
2
Do not exceed the maximum pressure and temperature
for the pressure rating of the body material used,
even though the trims shown may have higher capabilities.
3
Trims 4 and 29 may be used up to 99 bar (1440 psi) with clean
dry gas. For process fluids other than clean dry gas,
Use trims 4 and 29 only up to 21 bar (300 psi).
4
Trims 1, 27, and 37H temperature limits can be extended
to 316C (600F) for non-oxidizing service or 260C
(500F) oxidizing service if PEEK anti-extrusion rings
are used with spring-loaded seal rings.
5
Use trim 37H instead of trim 37 for temperatures
above 210C (410F). Requires anti-extrusion rings and
spring-loaded seal rings for temperatures above 232C (450F).

1. For high-temperature air, hydrocarbons, and certain other chemicals and solvents. Not for use with steam or ammonia. Not recommended for water above 82_C (180_F).
2. Has excellent moisture resistance to hot water and steam and may be used with most fire-resistant hydraulic oils, but cannot be used with petroleum-based fluids and other hydrocarbons.
3. Cannot be used with fire-resistant hydraulic oils.
4. These parts not used with 137 mm (7 inch) ports or larger.
5. These materials not limiting factors.
6. This material may be used in temperatures up to 260_C (500_F) for oxidizing service.
7. Standard for NPS 8 valve regardless of cage and all NPS 1 thru 6 valves with Cavitrol III cages, optional in NPS 1 thru 6 valves with other than Cavitrol III cages.

1. Temperatures above 232_C (450_F) require PEEK anti-extrusion rings and spring-loaded seal ring. This option allows ET construction to be used up to 316_C (600_F) for non-oxidizing service
and 260_C (500_F) for oxidizing service.
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.
4. May be used down to -254_C (-425_F) if manufacturing process includes Charpy impact test.

1. These in-body process temperatures assume an outside, ambient temperature of 21_C (70_F) and no insulation on the bonnet. When using any packing at low process temperatures, a cast
extension bonnet may have to be used to prevent packing damage which could result from the formation of valve stem frost. Material selection for trim and other components will also be
limiting factors.
2. Temperatures above 232_C (450_F) require PEEK anti-extrusion rings and spring-loaded seal ring.

Notes:
1

Use trim 87 instead of trim 85 for nonlubricating fluids such as super-heated steam or dry gases between 149C (300F) and 232C (450F).
Do not exceed the maximum pressure and temperature for the pressure rating of the body material used, even though the trims shown may have higher capabilities.
3
Trim 85 may be used up to 99 bar (1440 psi) with clean dry gas. For process fluids other than clean dry gas, use trim 85 only up to
21 bar (300 psi).
4
Trim 87 temperature limits can be extended to 316C (600F) for non-oxidizing service or 260C (500F) for oxidizing service if PEEK anti-extrusion rings are used
with spring-loaded seal rings.
