A46Y/F Pilot operated Safety Valve

Product Name: Pilot operated Safety Valve
Product specifications: 25-200
Product features: Pilot operated safety relief valve is a novel safety valve structure. It is mainly used in the fields of oil and gas, chemical industry, power, metallurgy, and urban gas, and is the best overpressure protection device for pressure equipment, containers, or pipelines. Its main advantages are that it changes the direct action of the spring to the indirect action of the pilot valve, improving the sensitivity of the action. In addition, the main valve adopts a sleeve piston type and a double sealed valve seat structure, which has high action accuracy, good repeatability, fast reseating, no leakage, can carry high back pressure discharge, long working life, stable and reliable operation. It can also be calibrated online, and can automatically reseat after repeated starting and jumping discharge, with tight closure and easy operation and maintenance.
