One-way flow control valves only restrict the flow in one direction; in the reverse direction the full flow is freely available. One-way flow control valves are used, among other things, to set the speed of pneumatic cylinders.
The piston speed of both advancing and retracting pneumatic cylinders can be regulated using one-way flow control valves from Festo. This is achieved by reducing the flow rate in the exhaust air or supply air direction. The non-return function works in the opposite direction.
Below we present our highlights of one-way flow control valves from the Festo Core Range.
The Festo one-way flow control valves GRxA and GRxZ have proven themselves time and again for their precise flow rate adjustment. The polymer-metal combination makes them light, compact and sturdy – and they are available as ISO and NPT variants.
Compact, lightweight and easy to install – the one-way flow control valve for direct mounting on the actuator. Extremely easy to install and quick to commission
