Product features

The stainless steel pneumatic butterfly valve is a high-performance and long-life butterfly valve, which is mainly composed of pneumatic actuator and stainless steel butterfly valve. The valve body and disc plate are made of stainless steel, and are characterized by high temperature resistance, corrosion resistance, high pressure resistance, etc. The stainless steel pneumatic butterfly valve can be divided into flange, wafer or welding type according to different connection modes. It is not only suitable for on-off two position cut-off control, but also can be equipped with valve positioner to realize proportional adjustment of medium flow, temperature, pressure and other parameters. The stainless steel pneumatic butterfly valve can be widely used for switching off or regulating pipes under high temperature, high pressure, low temperature, fire protection, etc.

Advantages of stainless steel pneumatic butterfly valve:
 
1. Pneumatic stainless steel butterfly valve is compact in structure, small in size, light in weight, flexible in operation and convenient in use.
2. The stainless steel butterfly valve adopts three-dimensional eccentric elastic or multi-level hard sealing structure, with reliable sealing performance, among which the soft seal can achieve zero leakage;
3. Pneumatic stainless steel butterfly valve has the characteristics of high temperature resistance, high pressure resistance, corrosion resistance, wear resistance, etc.
4. It has a two-way sealing function and is easy to install. It is not controlled by the flow direction of the media and is not affected by the space position. It can be installed in any direction.

Operating principle of stainless steel pneumatic butterfly valve:
The stainless steel pneumatic butterfly valve uses compressed air (air compressor) as the power source to drive the pneumatic actuator through the reversing of the solenoid valve. The pneumatic actuator drives the disc to rotate back and forth from 0 to 90 °, so as to open and close the valve. The valve positioner can be assembled according to the working conditions to control the rotating opening of the disc plate, so as to achieve intelligent control of various parameters such as medium flow.
