The main advantages of pneumatic flange butterfly valves are simple structure, small size, light weight, and low cost.
This feature is particularly significant for pneumatic butterfly valves, which are installed in high-altitude tunnels and controlled by a two position five way solenoid valve for easy operation. They can also adjust the flow medium.
The fluid resistance is small, and the effective flow area of pneumatic disc valves with medium and large diameters is large when fully opened.
They can be opened and closed quickly and effortlessly. The disc wrench can be rotated 90 degrees to complete the opening and closing.
Due to the nearly equal force of the disc wrench on both sides of the shaft, the torque direction generated is opposite, so the opening and closing torque is small. Under low pressure, good sealing can be achieved.
The disc valve sealing materials include nitrile rubber, fluorine rubber, edible rubber, and PTFE lining, so the sealing performance is good, The hard sealed disc valve is a soft and hard laminated metal plate with the advantages of metal hard sealing and elastic sealing, and has excellent sealing performance regardless of low temperature.
