P1808 | Pilot-Operated Relief Valve / Back Pressure Regulator
BelGAS Regulators
The BelGAS P1808 is a pilot-operated relief valve and back pressure regulator designed to maintain upstream pressure and protect gas systems from overpressure conditions. Commonly used on gas separators and distribution systems, the P1808 provides controlled pressure relief with high flow capacity and precise setpoint control.
The unit operates based on the installed pilot, allowing it to function either as a back pressure regulator or a relief valve depending on system requirements. The pilot monitors pressure and modulates the main valve to achieve smooth, controlled flow, enabling the unit to reach wide-open capacity quickly when required.
Designed for flexibility and performance, the P1808 supports adjustable pressure settings from 3 to 125 PSIG and offers multiple configuration options including material selections, pilot trims, and accessory packages. Its robust construction and stainless steel internal components ensure reliable operation in demanding oil and gas environments.
