Pneumatic Butterfly Valve
The Pneumatic Butterfly Valve is a high-performance automated valve designed for efficient flow control and reliable shut-off in industrial pipeline systems. Equipped with a pneumatic actuator, the valve provides fast operation, accurate control, and easy integration with automated systems such as PLC, DCS, and SCADA.
Featuring a compact structure, lightweight design, low operating torque, and excellent sealing performance, the pneumatic butterfly valve is widely used for controlling liquids, gases, and other industrial media. It is suitable for applications requiring frequent operation, remote control, and automated process management.
The valve is available in wafer, lug, and flanged designs, with various sealing options including soft seal, rubber seat, PTFE seat, and metal seat to meet different working conditions.
