They may be used with natural, manufactured, mixed, LP, or LP gas-air mixture. RV12 RV20 RV47 CV47 RV48 Maxitrols original Straight-Thru-Flow design meets your needs for high capacities at low inlet pressures. The basic difference between S-T-F design and other type regulators lies in 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. Typical applications include all types of residential, commercial and industrial gas-fired appliances and equipment used on low pressure gas supply.
