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...
