Pilot operated pressure relief valve is a new structure of safety valve. Mainly used in petroleum, chemical, electric power, metallurgy and city gas and other fields, is pressurized equipment, container or pipeline optimal overpressure protection device. Its main advantage is the variable spring direct acting pilot valve indirect effect, improves the action sensitivity, and the main valve adopts a sleeve piston type, double seal valve structure, high action precision, good repeatability, return fast, no leakage, can bring high back pressure, long life, such as discharge working stable and reliable work, it also available online adjusting, opened repeatedly jumped after emissions, still can automatically back seat, tight closing, convenient operation and maintenance.
