Flow Control Valves – RFU and RFO Series
Unidirectional and bidirectional
Connections: 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)
Technical features
The unidirectional flow regulators were made with M5, G1/8, G1/4, G3/8 and G1/2 connections.
The G1/8 and G1/4 connections are available with two different types of adjustment (see diagrams).
The M5, G3/8 and G1/2 connections, on the other hand, have only one type of adjustment.
All models can be mounted on a panel, on cylinders or on the wall.
To choose the most suitable model we recommend:
1. calculate the quantity of air in Nl/min (see cylinder tables, final section of the catalogue);
2. establish how long the cylinder must take to complete its stroke;
3. check the flow diagrams (see pages 2/7.20.03 and 2/7.20.04).
