floating ball valve

详情

We are one of the reliable Manufacturers, Suppliers, and Exporters of Floating Ball Valve. The Floating Ball Valve, which we offer is greatly demanded for their smooth surface finish and precise designs. Floating Ball Valve promises a longer functional life, owing to its excellent weatherability, resistance against corrosion and high tensile strength.

Principle :

• The valve is provided with a floating ball which supported by two valve seats.
• Under the medium pressure effect, a certain displacement can be generated by the ball itself to be pressed onto the valve seat seal ring at the outlet, which ensures tightness at the outlet.
• The valve has a floating ball and two renewable seats, movable ball that can touch the downstream seat tightly due to the pressure of upstream medium to ensure sealing reliable.
• The valve is divided into such two structures as the single-body type and double-body type float ball valve structures
• Mainly designed with one piece or two pieces body.
