Pneumatic Cylinder Speed Control Valve

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.

Pneumatic cylinder speed control valve. These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. This circuit maintains a constant. Also known as 4 way and 5 3 closed center valves. How the fa series controls pneumatic cylinder speed.

They control the speed of air powered equipment by adjusting the volume of airflow. For use with polyurethane polyethylene or ptfe tubing these compact flow controls help control cylinder speed in pneumatic applications. Made of plastic and stainless steel parts they have excellent corrosion resistance. Legris miniature flow control is specially designed for use with small bore cylinders.

Speed control during a work stroke can be accomplished by regulating flow to the cylinder. It normally gives finer speed control than a meter out circuit. The mass flow of air leaving the pneumatic cylinder to atmosphere is controlled with the combination of an electronic mass flow control valve a mass flow monitor traditional four way five port solenoid valve and sometimes an additional electronic pressure regulator. The proportion air closed system valve is extremely precise.

The check valve allows free reverse flow when the cylinder retracts.
