A flow control valve is used on many gas, plumbing, and mechanical dispensing systems and devices. The best example of a flow control valve is the crank valve on a garden hose that regulates the flow of water when the valve is turned in the open direction. Flow control valve adjustments are similar on most valves, by turning the valve in the open or closed position. Some specialised valve controls are automatic or remote to prevent any unwanted manual adjustments.

For pneumatic systems, first check the pressure of the air line to ensure it is at the recommended level for the pneumatic cylinder&#;s operation.
In most pneumatic air flow lines, there are usually two pneumatic flow control valves with the air cylinders. One gate valve is usually located at the base of the cylinder while the other one is at the top. Both valves are connected to the air supply pipe.
Remove the adjustment screw access cap located at the base of the cylinder on the flow control. Turn the cap counterclockwise to remove it. Use lock-jaw pliers if the cap is tight.
Turn the adjustment screw in a counter-clockwise motion to increase the airflow to the cylinder. This raises the rate of extension of the actuator arm. Turn the screw slowly with a flathead screwdriver to make small adjustments with every 1/8 turn.

Turn the adjustment screw in a clockwise direction to decrease the airflow. This will result in a decrease in the actuator arm extension rate.
Check the rate of the arm speed as adjustments are made to the flow valve until the rate is satisfactory. Use the recommended number of turns or fractional turns needed to open to the desired pressure. Replace the flow control screw access cap and tighten the cap. Repeat the whole process for the flow control valve on top of the cylinder.
Make sure that the valve controls are tightened or locked using an adjustment retainer. Make some hand and wrench adjustments if necessary to tighten up any screws, valve controls, or the screw cap to prevent any nuts from coming loose under normal use.
