In-line Flow Control Valves Series RFU - RFO
BSP/Metric
Panel or wall-mounted flow controllers
Unidirectional RFU and bidirectional RFO
Ports M5, G1/8, G1/4
Nominal diameter:
M5 = 1.5 mm (10-32 UNF)
G1/8 = 2 and 3mm
G1/4 = 4 and 6mm
The undirectional flow controllers are
equipped with M5, G1/8 and G1/4 ports,
each of which is available with two different
types of adjustment (see diagrams).
They are used mainly for controlling
the speed of cylinders.
They may be mounted on control panels
or cylinders, as required.
Bidirectional controllers are also available
with the same bodies, but suitably modified.
