Description

a pneumatic valve is a device that is used to control or modulate the flow of air (or another inert gas) in a pneumatic system. They do so by controlling the air or gas at the source, regulating its passage as needed into tubing, pipes, or devices in an automated pneumatic system.

The main functions of electrically-actuated directional control valves include: connecting or shutting off the compressed air supply, retracting and advancing cylinder drives.
