Air Flow Control Valve Operation

Selecting the right flow control valve.

Air flow control valve operation.

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. In automatic control terminology a control valve is termed a final control element. 4 way 3 position manual air control valves provide high flow. Balanced spool and sleeve design with easy operation regardless of system pressure.

Due to the free central flow design and automatic self cleaning feature of the segment edges during valve operation flushing connections are provided. A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure temperature and liquid level. Also known as 4 way and 5 3 closed center valves.

Unlike a needle valve a flow control valve regulates air flow in only one direction allowing free flow in the opposite direction. Valves operate with lubricated or nonlubricated compressed air and are easily plumbed into the system. These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. Flow control valves are used to reduce the rate of flow in a section of a pneumatic circuit resulting in a slower actuator speed.
