• Minimize Sudden Downstream Load Change • Wide Pressure Ranges • Full Relief Valve The BelGAS P212 gas pressure regulator is a direct operating, spring loaded adjustable regulator, used in applications where pressure reduction is required. The P212 is built on the reliable and time proven P202 platform and has been enhanced to offer a full relieving regulator through the diaphragm relief device. When used with a 2.5" bonnet vent port, the P212 becomes a fully relieving pressure regulator. Available in pressure ranges from 2" of water column up to 5 PSIG, making them ideal for use in applications where wide variations in pressure reduction are also required. The BelGAS Type P212 is offered with choice of ductile cast iron or WCB steel body, flanged or threaded. Applications • Compressors • Gas Engines • Service Regulators Materials of Construction P212 Series Maximum Inlet Pressure
