Pilot operated safety valve This type of safety valve uses the flowing medium itself, through a pilot valve, to apply the closing force on the safety valve 

1 GENERAL VALVE DESCRIPTION Operation The Series 727 Pilot Operated Safety Valves uses the principle of loading the larger area of a differential area piston with line pressure to hold the piston closed up to set pressure. On rising system pressure, the pilot actuates at set pressure, venting pressure from the main valve dome chamber.

Pilot-operated valves are pressure relief valves that control the main valve's inlet and outlet port. They are similar to spring-loaded valves but are the best alternative solution for reaching the highest pressure and highest capacity. These valves offer excellent performance for overpressure protection.
