The MacoTango Self-Operated Low-Pressure Regulator controls pressure at low setpoints using a sensitive self-operated sensing arrangement.
At low pressures, sensing-line losses and the selected spring or diaphragm range can materially influence control. The pressure reference must be identified as gauge, absolute or differential rather than omitted.
For low-pressure duty, provide a narrow operating envelope with clear pressure units. The sensing-line route and reference pressure can be as important as the nominal body size.
Consider this design for compatible low-pressure gas or process duties within its verified operating limits. Specify the normal setpoint, allowed deviation and upstream pressure variation, not just a broad catalogue range.
| Nominal size | DN15–150 |
|---|---|
| Nominal pressure options | PN16 or PN40; allowable differential varies with size |
| Set-pressure options | Overlapping spring ranges covering 0.5–100 kPa; specify the actual setpoint |
| Minimum operating differential | 0.01 MPa |
| Working temperature | Up to 80 °C for the listed arrangement |
| Flow characteristic | Linear |
| Regulating energy | Process-medium pressure |
| Rating basis | Series options are not simultaneous operating limits. Select the size, material, seat and pressure-temperature combination for the stated duty. |

We will confirm the final configuration and datasheet against the stated duty before order acceptance.
A low setpoint can be misinterpreted if kPa, mbar or the pressure reference is missing. State the value, unit and whether it is gauge, absolute or differential.
No. Low setpoint and differential-pressure control are different descriptions. Specify whether one pressure or the difference between two points is controlled.
