The SR Series Pressure Reducing Regulator is designed for industrial furnaces and heating applications. These regulators will maintain a constant outlet pressure over a wide range of flows even if the inlet pressure varies. Several spring ranges are available, from 4'' W.C. to 3 psig. Pilot loaded regulators, the SR-PC series, are also available for higher pressures and flows. Standard construction is for clean fuel gases including Natural Gas, Propane, Butane and other Hydrocarbon fuels. Special construction is available for gases such as Coke Oven Gas. The standard model is limited to fluids at temperatures of 150°F. Special models are available for temperatures to 700°F. The standard design has internal compensation. For capacities greater than listed in the table the regulator can be supplied with external compensation. The SR Series Reducing Regulators operate with inlet pressures in the range of 1 psig to 25 psig and delivery pressures from 2'' W.C. to 5 psig. The upper diaphragm chamber is normally open to atmosphere while the lower diaphragm chamber, by means of the impulse connection, is subject to outlet pressure. The seal diaphragm is designed so that its area equals the effective area of the valve disc. Fluctuations in inlet pressure are thus counterbalanced by these two equal areas. A compression spring loads the main diaphragm with an adjustable force which places the valve in an open position. When the outlet pressure under the main diaphragm equals the spring load, a balance of forces occurs to move the diaphragm and the valve assembly towards the closed position and maintain a constant delivery pressure.
