Overview of Pneumatic O-Type Ball Valve Products

Pneumatic V-shaped ball valve, with a V-shaped core, can achieve linear adjustment and has a large adjustable range. When the valve is closed. The V-shaped notch and valve seat create a scissor like effect, which not only has self-cleaning function but also prevents the ball core from getting stuck, making it particularly suitable for pipeline scaling and freezing situations. Suitable for controlling pulp, wastewater, solid suspension media containing fibers and particles, as well as powdery and granular media. The ZGH series cylinder piston actuator used has a simple structure and a large output torque. 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 form, 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 or open position 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.
