Maxitrol Zero Governor Regulator

The R & RS series is intended for use with both main burner and pilot load applications. The double diaphragm balanced valve design makes it possible to build a regulator physically small in size yet having good capacity characteristics. They are able to maintain steady outlet pressure control with widely varying inlet pressures. The high quality molded balancing diaphragm eliminates the inlet pressure effect acting on the valve. The housings are rugged aluminum die castings. All internal components are carefully selected and corrosion resistant. The diaphragms are of high quality supported synthetic rubber components having excellent low temperature performance. The RS models incorporate a resilient chemically bonded synthetic rubber ring on the valve member. The soft seating insures satisfactory pilot control at inlet pressures up to 5 psi.

These regulators are ideally suited for use with infrared heaters and pilot lines on large industrial heaters and boilers. They may also be used in residential applications. Because of their high pressure drop capacities, both the R & RS models will operate satisfactorily on domestic as well as elevated pressures. Appliances may be shipped to any area having supply pressures from 7.0\'\' W.C. to 5 psi without changing regulators.

They find wide applications on commercial and industrial equipment, especially where precise outlet pressure accuracy is required. Any of the R models can be furnished for zero governor applications.
