The basic difference between S -T -F design and other type regulators ties 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. The improved flowpattern provides accurate sensitive regulation at extremely low pressure differentials. The ability of the regulator to handle large capacity appliances with limited supply pressure offers a definite advantage to designers ofcommercial and industrial gas-€ired equipment. Models up to the three inch pipe size have high strength pressure cast aluminum housings. The RV 31 four inch model is of cast iron and steel construction.
