Title: Low Pressure Regulators

Abstract: Low pressure regulators are used for reduction of pressure in distribution systems, for controlling pressure to industrial furnaces and commercial heating applications and for domestic appliances such as water heaters, furnaces, gas refrigerators, and pilot lights. For distribution systems low pressure regulators are generally of the balanced valve type and are usually either weight or pilot loaded. Where inlet pressures reach twentyfive or fifty pounds per square inch and volumes are relatively large, it can be readily seen that a balanced valve is suitable. For example, if a single valve seat one square inch in area is used to reduce a pressure of fifty pounds per square inch to eight inches water column pressure and a lockup of two inches water column is specified, the two inches would have to be multiplied enough by the diaphragm and leverage to overcome the fifty pound thrust against the valve.
