Pneumatic Cylinder Operated Control Valve

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.

Air piloted valves are operated by an external air source such as a solenoid operated valve in a remote location. Pneumatic flow control and needle valves regulate the flow of compressed air. 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. For use with polyurethane polyethylene or ptfe tubing these compact flow controls help control cylinder speed in pneumatic applications.

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. Three way valves direct pressurized air to the cap end side of the cylinder. Solenoid air control valves rely on electromagnetic levers for controlling air flow and release to achieve proper compressor function.

Pneumatic threshold sensors detect the end of an air cylinder stroke and signal when pressure drops. These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. Legris miniature flow control is specially designed for use with small bore cylinders.
