Pneumatic sanitary butterfly valve food-Shanghai Yuwang-Product Overview:

    Pneumatic sanitary butterfly valve is composed of pneumatic actuator and butterfly valve. The pneumatic sanitary butterfly valve uses a circular butterfly plate that rotates with the valve to make the opening and closing performance. The pneumatic valve is mainly used as a cut-off valve to realize the activation action. It can also be designed to have the function of adjustment or segment valve and adjustment. Pneumatic flange Fluorine-lined butterfly valves are increasingly used in low-pressure large and medium-caliber pipelines.


            Pneumatic sanitary butterfly valve food-Shanghai Yuwang product features:

  • The pneumatic sanitary butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts;

  • Only need to rotate 90° to open and close quickly, simple operation;

  • The valve has good fluid control characteristics;

Pneumatic hard seal butterfly valve-Shanghai Yuwang Valve

       1. The pneumatic wafer butterfly valve is simple in structure, small in size and light in weight. It consists of only a few parts and is easy to install.
       2. When the pneumatic wafer butterfly valve is in the fully open position, the thickness of the butterfly plate is the resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so Has good flow control characteristics.
       3. The pneumatic wafer butterfly valve has two sealing types: elastic seal and metal seal. Elastic sealing valve, the sealing ring can be inlaid on the valve body or attached to the periphery of the butterfly plate.
       4. The pneumatic wafer butterfly valve has a long life, but it is difficult to achieve a complete seal. The metal seal can adapt to higher working temperature, while the elastic seal has the defect of being limited by temperature.
       5. The clever wedge-shaped design enables the pneumatic wafer ball valve to have an automatic sealing function that is more closed and tighter.
