Pneumatic V-shaped regulating ball valve

The ZSHV series pneumatic V-shaped ball valve has a V-shaped core, which can achieve linear adjustment with a large adjustable range. When the valve is closed, a wedge-shaped shear effect is generated between the V-shaped notch and the valve seat, and it has both self-cleaning function and can prevent the core from getting stuck. It is particularly suitable for pipeline scaling and freezing fields Suitable for controlling pulp, wastewater, solid suspension media containing fibers and particles, and powder particle control media The ZGH series cylinder piston actuator used has a simple structure and high torque transmission This series of ball valves is divided into soft seals and hard seals according to their sealing performance; According to the adjustment method, it can be divided into adjustment type and cutting type. Cutting type can be divided into single acting type and double acting type according to the action type, while adjustment type is double acting type The unique advantage of single acting type is that once the power source fails, the ball valve will automatically be in the closed and open positions according to the requirements of the control system The product is widely used in fields such as electricity, petroleum, chemical, papermaking, textile, food, pharmaceuticals, aerospace, etc
