More Information about Flow Control Valves for Compressed Air
Flow control valves control a cylinder's speed by adjusting the flow of air out of a cylinder.
Containing a metering needle and a check valve, flow control valves restrict the flow in one direction only. Air entering the valve in one direction is blocked by the check valve and is forced to pass through the needle valve. The setting on the needle valve is adjusted to determine the rate of flow. When the air flow is in the opposite direction it passes unrestricted through the check valve.
The rule of thumb for compressed air is 'If in doubt, meter-out'. The term ‘meter-out’ indicates that the air leaving the cylinder is controlled. Smooth speed control can be attained by restricting the flow of air that leaves the cylinder.
