The unidirectional and bidirectional flow controllers are equipped with M5, G1/8 and G1/4 ports, each of which is available with two different types of adjustment , except for the M5. They are used mainly for controlling the speed of cylinders. They may be mounted on control panels or cylinders, as required.
Unidirectional Flow Controller Series RFU
To regulate the speed of a cylinder, the air flow from the chamber which is being discharged must be regulated.
Bidirectional flow controller Series RFO
The bidirectional flow controller is suitable for regulating the air flow in both directions and for pressurising or depressurising containers.
