Pneumatic Butterfly Valve
9 products found
A pneumatic butterfly valve is an automated, quarter-turn rotary valve that utilizes compressed air to actuate an internal disc for quick-acting fluid isolation or flow modulation. When the pneumatic actuator receives a pneumatic signal, the internal air pressure drives a rack-and-pinion piston or diaphragm assembly, translating linear force into 90-degree rotational torque. This movement turns the valve stem and disc to open, close, or partially throttle the flow path, offering a fast-response time ideal for emergency shutdown systems (ESD) and high-frequency cycling. These automated valves feature lightweight, compact wafer, lug, or double-flange bodies fabricated from ductile iron, carbon steel, or stainless steel. Automation engineers and piping system contractors can optimize process loops and secure reliable, fast-acting flow control by importing certified pneumatic butterfly valves directly from leading manufacturers in China via our advanced B2B commercial platform.
