The RV Relief Valve is designed for use in high purity semiconductor applications, and is also ideally suited for ultra-pure water and aggressive chemicals. The design utilizes a molded PFA body with precision-machined PTFE seats and diaphragm poppet. When a field set relief pressure is reached, the valve opens and permits flow. The valve resets when 25% of original setpoint is reached.
FEATURES:
-
One piece precision machined diaphragm poppet manufactured from the latest technology modified PTFE. Provides over five times the flexural life as compared to conventional PTFE. Benefits are high cycle life, lower replacement costs and less downtime.
-
Tongue and groove seat and diaphragm poppet for positive through flow shut off and diaphragm to body seal.
-
Field adjustable relief pressure prevents over pressurization in critical applications.
