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.
