Fisherr easy-et Cryogenic

Sliding-Stem Control Valves

Fisher easy-e cryogenic valves are globe-style,

single-port, valves featuring stainless steel

construction materials and fabricated extension

bonnets. Fisher ET-C and EWT-C valves are

pressure-balanced, whereastheFisherEZ-Cvalveisan

unbalanced design. These cryogenic valves are

designed to provide throttling or on-off control of

liquids and gases at cryogenic temperatures as low as

-198_C(-325_F).

When required, these rugged valves can reliably

provide tight shutoff for special applications within the

chemical and hydrocarbon processing industries, such

as certain liquefied natural gas services.

The high-capacity ET-C and EWT-C valves with

pressure-balanced trim allow the use of smaller,

lower-cost actuators, reducing installed costs in

high-pressure and high-flow-rate applications.

The easy-e Valve Family

Thesevalvesarepartoftheversatile easy-e family of

industrial control valves. Special features include:

 ET-C and EWT-C: Different cage/plug styles provide

particular flow characteristics for highly-specialized

applications. The standard cage comes in two

different flow characteristics:

J equal percentage

and

J linear.

 EZ-C: Interchangeable, restricted-capacity trims and

full-sized trims match a variety of process flow

demands for highly-specialized applications. The

standard plug is designed with three different flow

characteristics:

J equal percentage, J linear, and

J quick-opening.
