Floating ball valve

Product Description:

Principle of the float ball valve: This kind of ball valve has a floating ball supported by two valve seats. Under the medium pressure effect, a certain displacement can be generated by the ball itself so as to be pressed onto the valve seat seal ring at the outlet, guaranteeing tightness at the outlet.
Principle: This type of ball valve has a floating ball and two renewable seats, movable ball can touch the down stream seat tightly because of the pressure of up stream medium to ensure sealing reliable.
The float ball valve is mainly divided into such two structures as the single-body type and double-body type float ball valve structures
This type of floating mounted ball valve are mainly designed with one piece or two pieces body.
