A compact, highly accurate, direct-acting pressure relief valve. Factory preset to desired crack pressure and/or flow specifications. Internal adjustment provides tamper-proof safety against inadvertent pressure changes. Valves feature an encapsulated O-ring seal to prevent extrusion at higher differential pressures.
