Ball valve

Pneumatic O-type floating ball valve is a specially designed and carefully manufactured product based on the introduction of foreign advanced technology. 

When matched with electric valve positioner, solenoid valve, limit switch, air filter pressure reducing valve, 

it can control the operation and realize the adjustment of pressure, flow, temperature, liquid level and other parameters. 

It is powered by compressed air, and the valve stem drives the valve core to rotate 90° in the valve body, 

which can achieve a fully open-fully closed action. The product is divided into metal seal and soft seal according to its sealing performance. 

It has the characteristics of compact structure, small size, reliable operation, good sealing performance, 

easy maintenance, convenient installation, strong adaptability and so on. 

It is especially suitable for occasions where the medium is viscous, contains particles, and fibers. 

It can be widely used in petroleum, chemical, teaching equipment, light industry, high-pressure equipment, pharmacy, 

papermaking and other industrial automatic control systems for remote centralized control or local control.
