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 Overview
Forged steel flange type high pressure ball valve closing parts of the ball around the center line of the valve body for rotation to open and close a valve, the seal is embedded in the stainless steel valve seat, the metal valve seat is provided with a spring, when the sealing surface wear or burn, under the action of the spring to push the valve seat and the ball to form a metal seal.Exhibit unique automatic pressure release function, when the valve lumen medium pressure mor...
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...
