Pneumatic Cylinder Operated Control Valve

Pneumatic threshold sensors detect the end of an air cylinder stroke and signal when pressure drops.

Pneumatic cylinder operated control valve.

Three way valves direct pressurized air to the cap end side of the cylinder. 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. These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. The valves pressurize and exhaust one outlet port to control a single acting cylinder or pilot another valve.

Solenoid air control valves rely on electromagnetic levers for controlling air flow and release to achieve proper compressor function. 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. Typical solenoid control voltages are 12vdc 24 vac dc 120vac or 240vac.

Pneumatic flow control and needle valves regulate the flow of compressed air. Legris miniature flow control is specially designed for use with small bore cylinders. For use with polyurethane polyethylene or ptfe tubing these compact flow controls help control cylinder speed in pneumatic applications.
