Fisher® easy-e™ 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, whereas the Fisher EZ-Cvalve is an
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
These valves are part of the versatile easy-e family of
industrial control valves. Special features include:
m ET-Cand EWT-C: Different cage/plug styles provide
particular flow characteristics for highly-specialized
applications. The standard cage comes in two
different flow characteristics: B equal percentage
and M 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: B equal percentage, M linear, and
M quick-opening.
