The pilot-operated safety relief valve is a safety valve with a novel structure. Mainly used in the fields of oil and gas, electric power, metallurgy and city gas, it is the best overpressure protection device for pressurized equipment, containers or pipelines. Its main advantage is that the direct action of the spring is changed to the indirect action of the pilot valve, which improves the sensitivity of the action. The main valve adopts a sleeve piston type and a double-sealed valve seat structure. It has high action accuracy, good repeatability, quick seat return, no leakage, and It can discharge with high back pressure, has long working life, and is stable and reliable. It can also be adjusted online. After repeated startup and discharge, it can still automatically return to the seat, close tightly, and is easy to operate and maintain. Main parts materials
