Product Description
Internal thread and socket welded forged steel gate valve fluid resistance is small, open and close the torque required is small, can be used in the medium to flow in two directions of the ring network pipeline, that is, the flow of media is not restricted.When fully open, the erosion of the sealing surface by the working medium is smaller than that of the globe valve.The structure is simple, the manufacturing process is good, and the length of the structure is short.
