FESTO Flow control valves regulate the piston speed of pneumatic drives during the advance and return strokes. The one-way flow control valve works by restricting/regulating the flow rate of compressed air in exhaust air or supply air direction.
FESTO Flow Control valve series GRLA are one-way flow control valves. Other types of flow control valves are Exhaust airflow control valves, Precision flow control valves, Non-Return valves, Time Delay valves etc.
Flow Regulator controls the volume of media passing through it, whereas a Pressure Regulator regulates the pressure of the media passing through it.
FESTO Flow Regulator (ex. GRLA-1/4-B) for compressed air in pneumatic circuits are used to control the speed of pneumatic cylinders mainly. While FESTO Pressure Regulator (ex. LR-1/4-D-MINI) for compressed air in pneumatic circuits regulate the force applied by the pneumatic cylinder
