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 structure characteristics
A check valve is an “automatic” valve that is opened for downstream flow and closed for counter-flow.Open the valve by the pressure of the medium in the system, and close the valve when the medium flows backwards.The operation varies with the type of check valve mechanism.The most common types of check valves are swing, lift (plug and ball), butterfly, check, and tilting disc.Products are widely used in petroleum, chemical, pharmaceutical, chemica...
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...
