Fisher™ 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 control of a wide variety of liquids and gases. 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 sales office 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-e family of Fisher industrial control valves. easy-e valves share the following characteristics.

n Multiple trim material choices

n Trim temperature capability with standard metal

seats to 427_C (800_F)

n Flexible graphite gaskets

n Interchangeable, restricted-capacity trims and

full-flow trims to match variable process flow demands

n Trim part interchangeability that permits

reconfiguring the valve to a different design variation

W2174-3

FISHER ES CONTROL VALVE

WITH 657 ACTUATOR

n Different cage/plug styles provide particular flow

characteristics for highly-specialized applications. The standard cage comes in three different flow characteristics:



n quick-opening



n linear n equal percentage



n Whisper Trimt I cages (figure 1) that attenuate

aerodynamic noise in gaseous service are available for all sizes except the NPS 8 ES valve.

n Optional constructions provide material

compatibility with NACE MR0175-2002.

n 316 stainless steel packing box parts are standard

(including packing flange, studs, and nuts).

Features

n 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.

n Valve Plug Stability— Rugged cage guiding provides

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

n Economy— Streamlined flow passages provide

higher efficiency and greater capacities per initial investment.

n 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-e trim parts.

n Easy Maintenance— The valve can stay in the

pipeline during removal of trim parts for inspection or maintenance.

n 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.

n Compliance with European Standards— Valves are

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

n 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 issue; the specific standard must be specified.

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
