Top entrance ball valve is mainly applicable for pipeline and industry system such as petroleum, chemical engineering and nuclear power plants. Its body adopts an integrated design, reducing leak points. Its seat design is available for either soft or hard seal, easy for maintenance. It has a top entry and on line maintenance function. It has a lot of advantages, such as small fluid resistance, simple structure, small volume, light weight, reliable sealing, convenience for operation and maintenance, open and close quickly, as well as start and close flexibly.
Its most difference from common ball valve is that its maintenance can be made on pipe line and without dismounting from the pipe line. The back space seat structure is adopted for the seat and the rear portion of seat retainer is oblique angle to prevent accumulation of impurity from affecting back space of seat.
It’s featured by its small torque and reliable seal; and unlike common ball valve types, its seat with a spheroidal structure can adjust the seal position automatically.
