easy-e EZ-C easy-e cryogenic valves are globe-style, single-port, valves featuring stainless steel construction materials and fabricated extension bonnets. The EZ-C valve is an unbalanced design and is designed to provide throttling or on-off control of liquids and gases at cryogenic temperatures as low as -198°C (-325°F). Interchangeable, restricted-capacity trims and full-sized trims match a variety of process flow demands for highly-specialized applications.
