Pneumatic Gate Valve
12 products found
A pneumatic gate valve is an automated, linear-motion isolation valve equipped with a pneumatic actuator that utilizes compressed air to rapidly open or close a wedge or parallel gate disc. When compressed air is directed into the upper chamber of the pneumatic cylinder, it forces the internal piston and stem downward, driving the gate plate into the valve seat to block fluid flow. Reversing the air supply to the lower cylinder chamber pushes the piston upward, lifting the gate to provide an unobstructed, full-bore flow path with minimal pressure drop. Most industrial designs feature a manual handwheel override to permit mechanical operation during an air supply or power failure. Instrumentation engineers and refinery procurement networks can ensure rapid emergency shut-off and reliable automation by importing certified pneumatic gate valves directly from premier manufacturers in China via our advanced B2B commercial platform.
