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.

Product Description
The ball of the floating ball valve is freely supported on the sealing ring. Under the action of fluid pressure, it is closely connected with the downstream sealing ring to form the downstream turbulent single-side seal.It is suitable for small caliber occasions.
Fixed ball ball valve ball with up and down rotating shaft, is fixed in the ball bearing, therefore, the ball is fixed, but the sealing ring is floating, the sealing ring with spring and fluid thrust pressure to t...
