Flow control valves in 316L stainless steel Series XRFU and XRFO
The unidirectional and bidirectional flow controllers are equipped with G1/8, G1/4, G3/8 and G1/2 ports. All models can be used in environments with aggressive fluids or gases.
General Data

| Valve group | Unidirectional and bidirectional controller |
| Materials | Body in 316L stainless steel, FKM seals |
| Mounting | With screws in the holes of the valve body or panel mounted |
| Threads | G1/8, G1/4, G3/8, G1/2 1/8 NPT, 1/4 NPT, 3/8 NPT, 1/2 NPT |
| Installation | In any position |
| Working temperature | -15°C +120°C |
| Working pressure | – 0,5 ÷ 16 bar (unidirectional regulator) 0 ÷ 40 bar (bidirectional regulator) |
| Nominal pressure | 6 bar |
| Nominal diameter Ø [mm] | G1/8 = 6 – G1/4 = 6 – G3/8 = 9 – G1/2 = 10 – PT1/8 = 6 – PT1/4 = 6 – PT3/8 = 9 – PT1/2 = 10 |
| Medium | Filtered air without lubrication with unidirectional and bidirectional flow control valves all fluids compatible with the materials of the bidirectional flow control valves |
