Series RFU and RFO
flow control valves
Unidirectional and bidirectional
Ports: M5, G1/8, G1/4, G3/8 and G1/2
Nominal diameters: 1,5 mm (M5), 2 and 3 mm (G1/8),
4 and 6 mm (G1/4), 7 mm (G3/8 and G1/2)
The unidirectional flow controllers are
equipped with M5, G1/8, G1/4, G3/8 and
G1/2 ports.
G1/8 and G1/4 ports are available with
two different types of adjustment (see
diagrams), whereas M5, G3/8 and G1/2
ports have just one type of adjustment.
All models can be panel or wall mounted
or they can be mounted on cylinders, as
required.
To choose the most suitable model, it is
recommended to:
1. calculate the quantity of air in Nl/min
(see the cylinders tables in the catalogue
appendix);
2. determine the stroke time of the
cylinder;
3. check the flow diagrams (see pages
2/7.20.03 and 2/7.20.04).
