BelGAS 300 Series - P303, P303H Pressure Reducing Regulators with Integrated Monitor
The BelGAS P303 and P303H gas pressure reducing regulators are available with a true monitor regulator, which acts independently of the main regulator. The monitor provides equivalent overpressure protection when compared to a standard two-regulator monitor setup. Should one regulator fail, the other regulator provides control and overpressure protections. The regulator’s fast action reduces the risk of shock from abrupt changes in downstream conditions and can help to prevent safety equipment from causing unnecessary, expensive, and time-consuming operation shutdowns.
Features:- Minimizes sudden downstream load changes
- Wide pressure range
- Integrated monitoring
- Compressors
- Gas Engines
- Service Regulators
