Aira Pneumatic valves control the flow, direction, and pressure of compressed air in pneumatic systems — used in manufacturing, automation, robotics, and industrial machinery. Here's a rundown of the main types:
By function
Directional control valves – route air to different parts of a circuit (e.g., extend/retract a cylinder). Classified by:
Ports and positions: e.g., 3/2 (3 ports, 2 positions), 5/2, 5/3 — the numbers describe how many connections and switching states the valve has.
Actuation method: manual (lever/button), mechanical (roller/plunger), pneumatic (pilot air), solenoid (electrically actuated), or a combination.
