Pneumatic Wafer Type Butterfly Valve
Introduction:
Pneumatic butterfly valve and pneumatic wafer type butterfly valve actuator adopt piston structure, featuring torque increase, flexible rotation, simple structure, small size and light weight. The valve body of the pneumatic wafer butterfly valve adopts several forms (central line, or tri eccentric metal seal, tetrafluoroethylene seal, and bi eccentric soft seal). The pneumatic wafer butterfly valve can be used in situations where the space required on site is relatively narrow and the pipeline distance is relatively short. The butterfly valve body has no connecting rod, bolt, etc., reliable operation, long service life, can be installed in multiple stations, and is not affected by the flow direction of the medium. The pneumatic wafer butterfly valve is widely used in the dust containing cold air or hot air pipeline of ventilation and environmental protection projects in the chemical industry, building materials, power plants, glass and other industries as a gas medium to regulate the flow or cut off the device.
Main features of pneumatic wafer butterfly valve:
1. Design, reasonable, unique structure, light weight, quick opening and closing.
2. The sealing element can be replaced, and the sealing performance is reliable to achieve zero leakage of two-way sealing.
3. The sealing material has the characteristics of aging resistance, corrosion resistance and long service life.
4. The two-part valve rod is connected without pin, with simple and compact structure and convenient maintenance.
5. The valve seat seal is integrated with the backrest to reduce the deformation of the valve seat.
6. The axial positioning device of the valve stem increases the sealing performance and reduces the torque of the valve.
7. It can be installed in any position and is convenient for maintenance.
