P99 | Pilot-Operated Pressure Reducing Regulator
BelGAS Regulators
The BelGAS P99 is a high-performance, pilot-operated pressure reducing regulator engineered to deliver precise and stable downstream pressure control across a wide range of operating conditions. Designed for accuracy and reliability, the P99 maintains consistent outlet pressure despite fluctuations in inlet pressure and flow demand.
Utilizing a pilot-controlled system with a double diaphragm design, the P99 provides faster response, tighter control, and reduced droop compared to traditional direct-operated regulators. This makes it ideal for applications requiring high accuracy and dependable pressure regulation.
The system is also compatible with monitor configurations, allowing a secondary regulator to act as overpressure protection in the event of primary regulator failure.
Typical Applications:
City gate stations, commercial buildings, boilers, furnaces, ovens, and plant air systems
