Features and benefits of pneumatic flange butterfly valve

Release Date: December 12, 2018

The butterfly valve is designed with the principle of three-dimensional eccentricity, which makes the space motion trajectory of the sealing surfaces ideal, and the sealing surfaces have no friction, no interference, and the proper selection of sealing materials, so that the sealing, corrosion resistance and resistance of the butterfly valve High temperature resistance and abrasion resistance are reliably guaranteed. Its main features are as follows:

1. Small opening torque, flexible and convenient, energy saving.

2. The three-dimensional structure of the heart makes the butterfly plate closer and tighter, and its sealing performance is reliable and no leakage is achieved.

3. High pressure resistance, corrosion resistance, wear resistance and long service life.

The pneumatic flange butterfly valve is composed of an angular stroke pneumatic piston actuator and a butterfly valve body. The main advantages are simple structure, small size, light weight, and low cost. This feature is particularly prominent in pneumatic flanged disc valves. The five-way solenoid valve is easy to control and can also adjust the flow medium.

The fluid resistance is small, the effective flow area is large when the large-diameter pneumatic flange butterfly valve is fully opened, and the opening and closing is quick and labor-saving. The opening and closing can be completed by turning the disc at 90 degrees, because the medium force of the disc plate on both sides of the shaft is nearly equal The resulting torque is in the opposite direction, so the opening and closing torque is small, and a good seal can be achieved at low pressure. The pneumatic flange butterfly valve has sealing materials such as nitrile rubber and fluorine rubber. The hard seal disc valve is a multi-level metal hard seal. It has the advantages of elastic sealing, and has excellent sealing performance under low temperature conditions. Therefore, pneumatic flange butterfly valve is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and pipes for corrosive media such as water supply and drainage.
