Pneumatic wafer butterfly valves feature a disc-shaped valve plate that functions to open
and close the fluid channel as the valve stem moves. The valve plate is installed along the
diameter of the pipes, and within the cylindrical channels of the valve body, the disc-
shaped plate rotates around its axis. The rotation angle ranges from 0� to 90�, with
the
valve being fully open when the plate reaches 90�.

These valves are known for their simple structure, compact size, lightweight design, low
material consumption, and quick operation. They provide a 90� reciprocating rotary
motion
with low driving torque, making them ideal for rapid opening and closing. Pneumatic wafer
butterfly valves are widely used for isolation, connection, and flow regulation in pipelines,
and they offer excellent flow control and sealing performance.

Additionally, these valves are effective in handling slurry and other media, with minimal
liquid accumulation in the apertures. They can achieve reliable sealing under low pressure
and deliver excellent flow adjustment performance.
