Fisherr ES and EAS
Sliding-Stem Control Valves

Fisher ES and EAS general-purpose control valves
(figures 1 and 2) are used for throttling or on-off
controlofawidevarietyofliquidsandgases.Both
valve designs have single ports, unbalanced valve
plugs, and cage guiding.

In both designs, metal-to-metal seating is standard for
all general applications over a wide range of pressure
drops and temperatures. Metal-to-PTFE seating is
optional for more stringent shutoff requirements.

The Fisher ES 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-e™ Valve Family

ES and EAS valves are part of the versatile easy-efamily
of Fisher industrial control valves. easy-evalvesshare
the following characteristics.

 Multiple trim material choices

 Trim temperature capability with standard metal

seats to 427_C (800_F)

 Flexible graphite gaskets

 Interchangeable, restricted-capacity trims and

full-flow trims to match variable process flow
demands

 Trim part interchangeability that permits

reconfiguring the valve to a different design
variation

Features

 Compliance with the Clean Air Act– Optional

ENVIRO-SEAL™ packing systems (figure 3) provide
an improved stem seal to help prevent the loss of
process fluid. The ENVIRO-SEAL packing systems
feature PTFE, Graphite ULF, or Duplex packing with
live-loading for reduced packing maintenance.

 Valve Plug Stability– Rugged cage guiding provides

increased valve plug stability, which reduces
vibration and mechanical noise.

 Economy– Streamlined flow passages provide

higher efficiency and greater capacities per initial
investment.

 Cost-Effective Operation– Increased wear

resistance of the standard hardened stainless steel
trim means long-lasting service. Also, trim inventory
costs are cut because dimensional standardization
permits use of most standard easy-etrimparts.

 Easy Maintenance– The valve can stay in the

pipeline during removal of trim parts for inspection
or maintenance.

 Long-Lasting Shutoff Capability with PTFE Seating–

Controlled compression of optional seat
construction protects PTFE disk between metal disk
seat and disk retainer (figure 1). The flowstream
contacts only the edge of the disk during normal
operation.

 Compliance with European Standards– Valves are

available with dimensions specified by EN/DIN
standards. See figure 7 and the note in figure 8.

 Sour Service Capability– Unless otherwise noted,

references are to NACE MR0175-2002. Optional
materials are available to meet NACE MR0103 and
NACE MR0175 / ISO15156. Material requirements
under these standards vary by edition and year of

ENVIRO-SEAL, HIGH-SEAL
Packing Systems

ENVIRO-SEAL and HIGH-SEAL packing systems offer
excellent sealing capabilities. They easily install in your
existing valves or can be purchased with new valves.
These systems may help prevent the loss of process
fluid. The long operational life and reliability of these
systems also helps to reduce your maintenance costs
and downtime.

For applications requiring compliance with
environmental protection regulations, the unique
Fisher ENVIRO-SEAL packing system (figure 3) and a
unique ENVIRO-SEAL bellows seal system (figure 4) are
offered. The emission control packing system helps to
keep emission concentrations below the EPA 100 ppm
requirement.

For an excellent stem seal in applications that are not
environmentally-sensitive, the Fisher HIGH-SEAL

Graphite ULF packing system is offered. The
HIGH-SEAL packing system provides excellent sealing
at pressure/temperature ratings beyond ENVIRO-SEAL
limits.

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

Class VI Shutoff
Capabilities

ES valves with metal seat constructions can provide
ANSI/FCI Class VI shutoff capabilities. See tables 1 and
