Flow control valves Series GSCU, GMCU, GSVU, GMVU, GSCO, GMCO
Unidirectional and bidirectional banjo flow controllers with nominal diameter 1,5 – 3,5 – 5 mm
Ports: M5, G1/8 and G1/4
Ports: M5, G1/8 and G1/4
These unidirectional and bidirectional flow controllers have been designed as small as possible to enable mounting directly on valves or cylinders.
The flow regulation range is wide and gradual, allowing the regulation to be very accurate either at minimum or maximum flow.

General Data
| Construction | Needle – type |
| Valve group | Unidirectional and bidirectional controller |
| Materials | Body and screws M5 inox; 1/8 – 1/4 – 3/8 – 1/2 OT58 seals NBR |
| Mounting | By male threaded |
| Installation | In any position |
| Operating temperature | 0°C ÷ 80°C (with dry air -20°C) |
| Operating pressure | 1 ÷ 10 bar |
| Nominal pressure | 6 bar |
| Nominal flow | See graph |
| Nominal diameter Ø [mm] | M5 = 1.5 mm – G1/8 = 2 mm – G1/4 = 4 mm G3/8 = 7 mm – G1/2 = 12 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. |
Coding Example
| GM | CU | 9 | 03 | – | 1/8 | – | 6 |
| GM | ACTUATION GM = Manual GS = Screwdriver |
| CU | ASSEMBLY CU = On cylinders unidirectional VU = On valves unidirectional CO = Bidirectional |
| 9 | VERSIONS 8 = Needle (screwdriver operated) 9 = Needle (manually operated) |
| 03 | FLOW CONTROL RANGE 13 (size = 1,5 / Ø tube = 3) 14 (size = 1,5 / Ø tube = 4) 03 (size = 3,5 / Ø tube = 6) 04 (size = 3,5 / Ø tube = 8) 05 (size = 5 / Ø tube = 8) 06 (size = 5 / Ø tube = 10) |
| 1/8 | PORTS M5 1/8 1/4 |
| 6 | Ø TUBE 3 4 6 8 10 |
To ensure the right choice of unidirectional flow controller, proceed as follows: calculate the quantity of air in Nl/min (see cylinder Table); determine the stroke time of the cylinder; refer to graph to see which controller is the right type.
