Product features

The pneumatic high-pressure ball valve is composed of flange / internal thread forged high-pressure ball valve and pneumatic actuator. The material of the valve body has been treated with hard and anti-corrosion treatment, which improves the strength of the valve body and has the advantages of excellent pressure resistance and wear resistance. Pneumatic high-pressure ball valve adopts three-stage valve body, which makes the structure more compact and easy to assemble. It is suitable for hydraulic oil, water, high-pressure gas and other media. The valve positioner can input 4-20mA analog signal to control the opening of ball core operation, and realize the proportional adjustment of medium pressure, flow, temperature and other parameters.

 
Pneumatic high pressure ball valve applications:
1. The valve body is made by forging process, which improves the strength of the material and avoids the defects such as blowhole and sand hole.
2. The sealing ring is made of nylon material, which bears higher pressure than polytetrafluoroethylene, has long service life and good sealing performance.
3. Even under the maximum working pressure, the high pressure pneumatic ball valve can keep the pressure uniformity of the valve structure.
4. It is widely used in chemical industry, petroleum, natural gas, metallurgy and other industries as well as long-distance natural gas pipeline with hydrogen sulfide medium, impurities and serious corrosion.
