Pressure relief valves are designed and engineered to provide high-volume discharge primarily for use on liquid receiver applications above the liquid refrigerant level. Models are available with multiple seat configurations, high pressure settings, and certified for use with R410a refrigerant. Combine a relief valve with rupture disc to relieve an over pressure condition and pressure gauge to reveal visual indication.
RELIEFMASTER® Change-Over Manifold
Designed to provide continuous system protection in the event of relief valve rupture, RELIEFMASTER® Change-Over Manifolds use a common body chamber to serve as the base for two independent relief valves. A system can remain fully operational when valves require service or replacement.
