Abstract: Low pressure regulators are available in a wide variety ol sizes and designs. This wide range of manufacture permits the solution of each particular problem of pressure regulator in the manner which is most satisfactory to the distribution department. In the design of these regulators, considerable attention has been paid to the selection of the proper material for each particular part of every type of regulator. The valve seat discs are furnished in leather or in neoprene in various degrees of hardness. The neoprene seat discs are recommended lor natural gas service, while leather seat discs are widely used for manufactured gas. The diaphragms are fabricated from sheepskin or flexible composition material. Sheepskin impregnated with an oil dressing is recommended for most lowpressure service. All of the castings are made of alloyed grey iron, which is unexcelled for uniformity and high tensile strength.
