Flow Control Valves for Pneumatic Control Systems

Flow is based on speed, whereas pressure is proportional to strength. When increasing the flow inside an actuator, users will begin to increase the speed. If pressure is increased, the resistance will also increase. Simply put, flow alters the rate, and pressure changes the force of the device. Valve positions direct the actuator. Pneumatic control systems help control the flow of air.

Flow control valves do not work without differentials between down and upstream. Flow control valves are used to control exiting pressure from exhausts. Ultimately, this causes pressure through a properly rated connection hose. The control valve does not direct exhaust air. The air is lost very slowly but is directly controlled by a flow control valve. We carry a full line of pneumatic valves.

Different flow control valve types exist to best suit the needs of unique applications. The three main types are:

Traditional control valves control flow, pressure, liquid level, and temperature by partially or fully closing and opening. These are the most commonly used control valves, but the devices are limited to either fully open or fully closed. The controls are of simple capabilities and design.

Needle control valves are considered variable control valves that are not pressure compensated. These valves create pressure differentials between the down and upstream. A shortcoming of the needle valve is that it restricts flow rates in both directions.

Ball valves have a perforated, pivoting, and hollow ball that directly controls flow. It will open when the hole is lined up with the current. It will close when rotated to 90-degrees—by way of valve handles.

Two other commonly used valves include globe and butterfly valves. For more information on flow controls, you should not hesitate to give us a call.
