Overview of af46y|f pilot steam safety valve

Pilot operated safety relief valve is a kind of safety valve with novel structure. It is mainly used in the fields of petroleum and natural gas, chemical industry, electric power, metallurgy and urban gas. It is the best overpressure protection device on pressure equipment, containers or pipelines. Its main advantage is to change the direct action of the spring into the indirect action of the pilot valve, which improves the sensitivity of the action. Moreover, the main valve adopts the sleeve piston type, double sealing seat structure, with high action accuracy, good repeatability, fast reseating, no leakage, high back pressure discharge, long service life, stable and reliable work. It can also be adjusted online. After repeated startup and jump discharge, it can still automatically reseat, close tightly, and operate and maintain conveniently.
