  • products details

YFL Steam jacketed safety valve has a thermal insulation jacket outside the body. The jacket is supplied with continuous circulated steam through the thermal insulation inlet and outlet to insure heat preservation of the medium inside the safety valves. And the sealing face surfaces are also flushed by steam through two flushing inlets simultaneously. 


The inlet and outlet flanges of the steam jacketed safety valves are enlarged and jacketed to make the whole safety valves with stable working temperature for the medium. The bellows in the steam jacketed safety valve protect the valves from erosion by corrosive medium and make sure there won't be outside leakage of medium.
