In-line Flow Control Valves - BSP/Metric

Unidirectional flow controller Series RFU

Part Number

RFU 452-M5

RFU 482-1/8

RFU 483-1/8

RFU 444-1/4

RFU 446-1/4

To regulate the speed of a cylinder, the air flow from the chamber which is being discharged must be regulated. For this reason, the unidirectional flow controller must be connected as follows:
- connect the threaded outlet marked A to the cylinder inlet and the threaded outlet marked B to the valve user port.
