Pneumatic Wafer Butterfly Valve
The pneumatic wafer butterfly valve consists of a pneumatic actuator and wafer-type butterfly valve body. It uses compressed air to rotate the disc by 90° to realize on-off and flow regulation of pipeline media. The wafer body is clamped between two flanges without extra flange bolts, widely used as on-off or control valve in industrial pipelines.

Core Features
Compact structure, light weight, small installation space. Wafer design for easy assembly and disassembly.
Pneumatic actuation with fast response. Can be equipped with solenoid valve, limit switch and positioner for remote automatic control.
90° rotation of disc, fast opening & closing. Available for on-off service or continuous flow control with valve positioner.
Sealing options: EPDM, NBR, FKM, PTFE, suitable for water, gas, weak acid & weak alkali media.
Low flow resistance and low pressure drop, good sealing performance under low pressure conditions.

Pneumatic Triple Eccentric Butterfly Valve
The pneumatic tri-eccentric butterfly valve is a type of butterfly valve that uses compressed air as the power source and achieves high-efficiency sealing through the design of a tri-eccentric structure. Its "tri-eccentricity" refers to the eccentric design of the valve disc and the valve seat in three dimensions (radial eccentricity, axial eccentricity, and angular eccentricity), which significantly improves the sealing performance and pressure resistance. It is suitable for harsh working conditions such as high temperature, high pressure, and high corrosion.
