FESTO GR One Way Flow Control Valve, Inline Installation Introducing the FESTO GR series. The series features a range of one-way flow control valve fittings. The valve fittings are combined within a housing. This allows the flow and return speed to be set separately for single or double acting cylinders. The GR series facilitates an efficient and reliable pressure system for compressed air and water. Features and Benefits

• This range by FESTO includes one way pneumatic flow control valves


• Maximum flexibility for pneumatic fittings


• Wide operating temperature range


• Available with a variety of different thread and diameter connector sizes, made from robust, solid materials


• Through-hole and front panel mounting


• Variations of tube and threading connection type options are available within the GR series

How do one way flow control valves work? Flow control valves automatically adjust to variations in pressure and temperature in order to regulate speed, which is done through restrictions on the flow rate of compressed air. With a one-way flow control valve, the flow control function only works in one direction.
