Vent Relief Valve
Vent Relief Valve is a compact, highly accurate, direct acting pressure relief valve. Factory preset to desired crack pressure and/or flow specifications.The Internal adjustment provides tamper proof safety against inadvertent pressure changes. This type of valves is available 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. Optional deflector cap increases flow capacity and provides for deflection of discharge.
