Introduction:
The R312E Series 2-PSI Service regulator serves as an intermediate regulator after the First-Stage regulator. This regulator is designed for Two-PSI LP-Gas regulator systems and is listed by Underwriter’s Laboratories. This unit reduces an inlet pressure of 10 PSIG (0,69 bar) to a nominal 2 PSIG (0,14 bar) outlet pressure.

The R312E Series typically supplies LP-Gas through corrugated stainless steel tubing (CSST) to a line regulator located inside the building. A manifold can be used with CSST for routing to a line pressure regulator supplying approximately 11-inches w.c. to appliance regulators. The regulator is colorcoded white to easily identify the unit as a 2-PSI Service regulator.
