Farris Engineering

Spring-Loaded and
Pilot-Operated Relief Valves

Since the early 1940s, the Farris Engineering unit of Curtiss-Wright Flow Control has designed and produced a wide range of spring-loaded and pilot-operated pressure relief valves. Used as safety devices, these valves prevent over-pressurization of vessels, pipelines, and equipment.  For more information on these products, please contact us at 918-584-7101 or email us at sales@thorcoinc.com.
