Air Flow Control Valve Operation

Flow control valves are used to reduce the rate of flow in a section of a pneumatic circuit resulting in a slower actuator speed. Designed for continuous operation particularly suitable for variable duties. In automatic control terminology a control valve is termed a final control element.

Valves operate with lubricated or nonlubricated compressed air and are easily plumbed into the system.

Air flow control valve operation.

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. Unlike a needle valve a flow control valve regulates air flow in only one direction allowing free flow in the opposite direction. Balanced spool and sleeve design with easy operation regardless of system pressure. This enables the direct control of flow rate and the consequential control of process quantities such as pressure temperature and liquid level.

These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. 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. 4 way 3 position manual air control valves provide high flow.

Selecting the right flow control valve. Simple installation and commissioning. Due to the free central flow design and automatic self cleaning feature of the segment edges during valve operation flushing connections are provided. Also known as 4 way and 5 3 closed center valves.

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.
