What is a Pneumatic Piston Control Valve?

Pneumatic piston valves are a type of valve that uses compressed air or other gases to move a piston or diaphragm that opens or closes the valve. These valves are widely used in industrial and manufacturing applications to control the flow of liquids, gases, and other materials. Depending on the number of ports they have, they can be two-way or three-way valves. Two-way valves have two ports, while three-way valves have three ports. The connection points are used to connect the valve to pipes or other equipment within the system.

They are known for their fast response times and high flow capacities, making them ideal for applications requiring precise control and quick switching. Additionally, they are relatively simple and easy to maintain, which makes them a popular choice in many industrial environments.

Operating Principle of the Control Valve

The valve remains closed (or open) under spring force in its normal state. When the piston is actuated by compressed air, the valve opens (or closes). In a double-acting type, the valve is open and compressed air is used to close it.

Pneumatic piston valves are Y-type valves made of a 316 stainless steel body and a 304 stainless steel actuator for pneumatic control purposes. They are manufactured as single-acting and normally closed types. The standard threaded connections are BSP threads.
