A pilot operated diaphragm valve built for high-pressure air service — where the standard PCN/PBN platform tops out around 12 Bar, the PBU forged-brass body and PUR diaphragm hold a stable normally-closed shut-off up to 40 Bar.
| Model No. | Port | Orifice | Max Pressure | Qn (LPM) |
|---|---|---|---|---|
| PBU-2Y | ½" | 15 mm | 40 Bar | 3150 |
| PBU-2ZY | ½" | 15 mm | 40 Bar | 3150 |
| PBU-3Y | ¾" | 15 mm | 40 Bar | 3550 |
| PBU-3ZY | ¾" | 15 mm | 40 Bar | 3550 |
Minimum operating pressure 1.5 Kg/cm² across the range.
High-pressure air distribution, pneumatic test benches, industrial compressor circuits and any utility line where standard 10-12 Bar diaphragm valves aren't rated for the working pressure.
