Pneumatic Flow Control Valve

The flow control valve fittings are used to reduce the actual flow rate in a definite section of a pneumatic circuit. This serves to decrease the actuator speed of the system. While a needle valve controls the flow in two directions, a flow control valve fitting is used to direct the system flow in only one direction. This way, free flow of the gas or liquid is allowed in the opposite direction.The system has a critical need for the flow stream to reach the right place at the suitable time. The actual control of the flow and pressure, to direct the energy transfer within the system, is of secondary importance. The secondary function of the directional valves and fittings, ensure the proper timing of the cyclic events.
