Pressure
Relief Valves

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.
