This valve is mounted in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates about the axis, the rotation angle is between 0°-90°, and when rotated to 90°, the valve is fully open. The pneumatic butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be quickly opened and closed by rotating 90°, and the operation is simple, and the explosion-proof pneumatic butterfly valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the disc is the resistance of the medium flowing through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics. Pneumatic butterfly valves are available in both metal and soft seal versions. The metal seal type is suitable for working conditions with temperatures above ≥250 degrees. The soft seal type is suitable for working conditions within ≤250 degrees.
1. The design is novel, reasonable, unique in structure, light in weight, and quick to open and close.
2. the operating torque is small, easy to operate, labor-saving and smart.
3. can be installed in any location, easy to maintain.
4. the seal can be replaced, the sealing performance is reliable to achieve two-way seal zero leakage.
5. The sealing material is resistant to aging, corrosion and long service life.
