Standard Safety Valves

Maximum Equipment Protection

Safety relief valves are automatic discharge valves that maintain the pressure of a circuit below the set limit. They are designed to allow an immediate discharge of the required capacity to relieve pressure instantly. Springs are designed and manufactured for high calibration accuracy and to maintain the elasticity coefficient constant over time. For operation with variable backpressure, the valve is equipped with a metallic bellow as an option.
