Flow Control Valves-KJN ENTERPRISES

Flow Control Valves are used in pneumatic circuit to control the flow rate of air in the circuit. The most common application of these valves is in the regulation of piston speeds of a power cylinder. They are installed directly on the ports of the cylinder in such a manner that the discharge from the cylinder is restricted whereas the inlet fluid coming from the valve to the cylinder has free flow. Thus these valves are installed on the port opposite to which pressurised air is being fed to move the piston. Speed regulation of both strokes in a double acting cylinder is achieved by use of two separate flow control valves on each port of the cylinder.
