One piece Body, Top Entry, Full Port, Fire-Safe and Anti-static, Free leakage of body Sealed construction, Low torque in operation, Double block&bleed(DBB), Various driving types, extension Stem It has a lot of advantages,such as small fluid resistance,simple structure,small volume,light weight,reliable saaling,convenience for operation and maintenance, open and close quickly,as well as start and close flexibly.
Function: is mainly used in pipeline and industry system and it has a top entry and on line maintenance function.
