P 212 Medium Commercial

The Belgas P 212 is a full-size medium commercial direct-operating, spring-loaded adjustable gas pressure regulator used in pressure reduction applications.

BelGAS Pressure Regulator

As a full-relieving regulator, the P212 increases downstream safety by keeping the pressure lower in the event of a failure. It also features an exclusive BelGAS flow director, which directs flow downstream to increase forward flow and, if there is excess pressure, the flow runs to the internal relief.

Features & Benefits

At the foundation of the P212 is the reliable and time-proven P202 platform; only it is enhanced, offering a full-relieving regulator through a diaphragm relief device. When using a 2.5" bonnet vent port, the P212 becomes a fully relieving pressure regulator.

The P212 is available in pressures ranging from 2" WC up to 5 PSIG, making them ideal for applications where wide variations in pressure reduction are also needed. The BelGAS P212 is available in ductile cast iron or WCB steel body, flanged or threaded.

The regulators have port sizes available from 1.25 NPT to 2 NPT and orifice sizes ranging 1/4" to 1-3/16".
