VENT RELIEF VALVE

A compact, highly accurate, direct-acting pressure relief valve. Factory preset to the desired crack pressure and/or flow specifications. Internal adjustment provides tamper-proof safety against inadvertent pressure changes. Available vent to atmosphere or inline configurations in brass, aluminum, and 316 stainless steel. Valves feature a Quad ring seal which provides for extreme accuracy and repeatability with a narrow reseal band. An optional deflector cap increases flow capacity and provides for deflection of discharge.
