Safety Valves act as a fail-safe for reciprocating plunger pump, pressure vessel and testing lines, etc. The open/close pressure is controlled by spring washer. When the pressure exceeds preset limit, the valve may automatically unload. When the pressure drops below preset limit, the valve may automatically close to protect people and equipment.
