Series RFU and RFO

Series RFU and RFO

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, 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
2. determine the stroke time of the cylinder;
3. check the flow diagrams

Construction Needle-type
Valve group Unidirectional and bidirectional controller
Materials AL body - brass needle (not nickel-plated) - NBR seals
Mounting With screws in the holes of the valve body or panel mounted
Threaded ports M5 - G1/8 - G1/4 - G3/8 - G1/2
Installation As required
Operating temperature 0°C ÷ 80°C (with dry air - 20°C)
Operating pressure 1 ÷ 10 bar (for models with M5 - G1/8 - G1/4 ports)
2 ÷ 10 bar (for models with G3/8 - G1/2 ports)
Nominal pressure 6 bar
Nominal flow See graph
Nominal diameter M5 = 1,5 - G1/8 = 2 or 3 mm - G1/4 = 4 or 6 mm - G3/8 and G1/2 = 7 mm
Fluid Filtered air. If lubricated air is used, it is recommended to use ISOVG 32 oil. Once applied the lubrication should never be interrupted.
