CIRCOR RV05-455-140 Circle Seal Pressure Relief Valve

The CIRCOR RV05-455-140 Circle Seal Relief Valve is a compact, spring-loaded pressure-relief device from Circor’s Circle Seal Controls lineup, configured as RV05-455-140 with a 140 psi cracking pressure. Part of the RV05-455 series, this inline relief valve uses Circle Seal seating to provide reliable overpressure protection for hydraulic and pneumatic systems by venting fluid when the process pressure exceeds the valve’s setpoint, then resealing as pressure falls. The model designation RV05-455-140 (2E1922-3) confirms the exact configuration and rating within Circor’s catalog, ensuring compatibility with other Circle Seal valve components in the same family. Applications for this valve include safeguards on equipment and circuits where precise relief at moderate pressures is required, such as test rigs, process lines, and machinery that operate within a controlled pressure window; its 140 psi rating makes it suitable for systems that demand a moderate, dependable relief threshold with Circle Seal’s emphasis on seating reliability and repeatable performance in demanding environments.
