The RP-1072 series regulator is restricted to vacuum applications. The range of pressures under control cannot vary beyond 0 psig and -14.7 psig.

The RP-1065 and RP-1066 diaphragm actuated pressure regulators are designed with spring adjusted pressure regulators and relief valves for steam service.

The RP-1070 and RP-1073 bellows actuated pressure regulators are simple, self-operated and offer sensitive, accurate control of reduced pressures. They may be used to control steam pressures for heating systems, industrial processes and steam driven pumps, and many other fluid pressure controlling and limiting applications.
