Pneumatic Cylinder Operated Control Valve

Legris miniature flow control is specially designed for use with small bore cylinders.

Pneumatic cylinder operated control valve. Pneumatic flow control and needle valves regulate the flow of compressed air. These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. Solenoid operated valves use an electrical coil to control the position of a poppet plunger or spool to open or close a valve. These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place.

For use with polyurethane polyethylene or ptfe tubing these compact flow controls help control cylinder speed in pneumatic applications. Often used to extend and then retract a cylinder at different speeds they create two actions and have two exhaust ports which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. Solenoid air control valves rely on electromagnetic levers for controlling air flow and release to achieve proper compressor function. Typical solenoid control voltages are 12vdc 24 vac dc 120vac or 240vac.

Air piloted valves are operated by an external air source such as a solenoid operated valve in a remote location. Three way valves direct pressurized air to the cap end side of the cylinder. The valves pressurize and exhaust one outlet port to control a single acting cylinder or pilot another valve.
