The BPRL Series of Pressure Relief Valves are a Bronze Easing Gear style valve with 316 Stainless Steel Entry and Internals. The Reinforced PTFE seat with 316 Stainless Steel internals gives this relief valve a wide range of applications. These valves are available as BSP threaded with equal inlet to outlet ports. The relieving pressure is easily adjustable by turning up or down the setting nut under the top cap. Easing Gear relief valves are generally preferred for applications where a manual override is required. Please note this relief valve is for general applications only and not intended for use as a Safety Relief Valve. Not recommended for use on liquid as the open top will allow media to escape when venting.
