Overview Of Pneumatic Butterfly Valve
Pneumatic butterfly valve is a butterfly plate rotating center (namely the center of the valve shaft), located in the central line of the valve body and butterfly valve seal section of the butterfly valve, the connection mode has the clamp type and flange type. Pneumatic butterfly valve fluid resistance small, medium and large caliber butterfly valve fully open when the effective flow area is large, open and close quickly and cost, the use of compressed air to drive the rotation angle to complete 90 disc pulling hoist, can also be assembled on electrical valve positioner of medium flow, pressure, temperature and other parameters for regulation and control.

Characteristics Of pneumatic Central Butterfly Valve
1. Small and lightweight, easy disassembly and maintenance, and can be installed at any place.
2. The structure is simple and compact, the operation torque is small, and the turning of 90 degrees is quick.
3. The flow characteristics of straight line, good regulation performance.
4. The connection between the butterfly plate and the valve stem adopts a pin free structure, which overcomes the possible leakage point.
5. The outer circle of the butterfly plate is made of spherical shape, which improves the sealing performance and prolongs the service life of the valve. Zero leakage is maintained even more than 50 thousand times with pressure opening and closing.
