Pressure Relief Valves

Safety relief valves are designed to be fast-acting components that protect systems with the potential for sudden pressure spikes. These valves may sit dormant for indeterminate amounts of time before needing to be used, so it’s crucial that they always work as intended. Our safety relief valves are available in low-leak and tight hysteresis configurations. We 100% test each component for crack, flow point and reseat pressure to ensure reliable operation.

These valves are available in a wide range of envelopes and cracking pressures for system pressures up to 5000 psi. Some models are available with integral safety screens for added protection from rogue debris and contamination.

When a fluidic system is subject to a rapid temperature change, the thermal expansion of fluids may potentially cause damage within the system. Thermal relief valves are designed to relieve small volumes of fluid to protect against thermal expansion. Due to the small passage size of thermal relief valves, they include an integral CRES low micron filter upstream of the valve seat to prevent internal silting due to ingested contamination.
