A piston-type, self-relieving pressure regulator built to hold a stable downstream set-point across a wide inlet range — engineered for high-pressure air distribution, test benches and process utility skids.
| Model | Port | Orifice | Inlet | Regulating | Flow |
|---|---|---|---|---|---|
| PB-W2 | ½" | 12mm | 3–42 Bar | 0–42 Bar | 2,500 LPM |
| PB-W3 | ¾" | 24mm | 3–42 Bar | 0–42 Bar | 8,000 LPM |
| PB-W4 | 1" | 24mm | 3–42 Bar | 0–42 Bar | 10,000 LPM |
PB Series regulators are specified on high-pressure air distribution headers, pressure test benches, gas boosting skids and anywhere a stable, adjustable downstream pressure is required from a variable high-pressure source.
