Product Description
Ball valve after more than half a century of development, now has become a widely used main valve class.The main function of the ball valve is to cut off and connect the fluid in the pipeline;It can also be used for fluid regulation and control.Ball valve has the characteristics of small flow resistance, good sealing, quick switching and high reliability.
Ball valve is mainly composed of valve body, valve cover, valve stem, ball and sealing ring and other parts, belongs to...

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.
