Belgas P212 Pressure Regulator

The BelGAS P212 Gas Pressure Regulator is a direct-acting, spring-loaded regulator designed for precise and reliable pressure reduction across a wide range of gas applications. Engineered on the proven P202 platform, the P212 incorporates enhanced functionality through its integrated diaphragm relief mechanism. When paired with the 2.5-inch bonnet vent port, the regulator becomes a fully relieving type, ensuring safe discharge of excess pressure and improved downstream stability.

With available set pressure ranges from 2 inches WC to 5 PSIG, the P212 offers exceptional flexibility, making it suitable for systems where significant variations in inlet and outlet pressures occur. The regulator can be constructed with either ductile cast iron or WCB steel bodies, and is available with threaded or flanged connections, allowing integration into a broad range of industrial gas systems.

Engineered to handle dynamic load conditions, the P212 is widely used in compressor systems, gas engines, and general service regulation applications where consistent downstream control and dependable overpressure protection are critical.
