Pneumatic Double Action Cut off Ball Valve
ZSHO/ZAJO series O type shut-off ball valve is a kind of quarter-turn on-off valve. It is mainly used for shut-off control of media. The ball valve of this series adopts round hole in the ball. When opened, it is directly connected to the body flow channel, featured by high flow capacity....
Principle of the cast steel floating 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 seat seal ring at the outlet, guaranteeing tightness at the outlet.
The floating ball valve is mainly divided into such two structures as the single-body type and double-body type float ball valve structures
The ball valve are designed in accordance with ISO17292,API 608,BS 5351,GB/T 12237;
Simple structure with good tightness and small torque;
Have reduce bore type and full bore type with the minimum flow resistance (zero actually);
