RV SERIES Rubber Seat Poppet Design The compact RV poppet regulators are designed primarily for main burner and pilot load applications. Typical applications include residential and commercial cooking appliances, barbecues, hearth products, and pilot lines. Maxitrol rubber seat poppet models offer the ultimate in design features and performance capabilities to meet your specific appliance or utility requirements. Specifications Pipe Sizes - 1/8" thru 3/4" threaded connections with NPT or ISO7-1 threads. (Other connections available, please consult Maxitrol Company.) Housing Material RV12, RV20, RV47, RV48, CV47: aluminum. RV47 Mounting All models, with the exception of "D" suffix models, are suitable for multi -positional mounting. Other than upright position will result in a slight difference in outlet pressure. "D" suffix models are to be mounted upright only. If ball check vent limiting device is installed, mount in an upright position only.

RV SERIES Straight-Thru-Flow Design Maxitrol's original straight-thru-flow (STF) design regulators are non -lockup type regulators for high capacities at low inlet pressures. The difference between STF design and other type regulators is the conical valve. The cone principal permits gas to flow straight through the regulator without changing directions. Frictional flow resistance is reduced, resulting in greater capacity. An improved flow pattern provides accurate, sensitive regulation at extremely low pressure differentials. typical applications include residential, commercial, and industrial gas -fired appliances and equipment used on low or medium pressure gas supplies.
