RH Series

Company Name : Hale Hamilton
Description: The RH series are dome-loaded regulators that provide a flow of gas or liquid at controlled pressure. The outlet pressure is set by adjusting the pressure in the dome. A flexible diaphragm separates the gas in the dome from the process fluid. The valve in the regulator is balanced by a piston. This piston is sized for the required outlet pressure range. A selection of piston sizes is available for each body size. The dome must be charged with an inert gas such as air or nitrogen. If the process gas is inert, it may be used to charge the dome – we call this “Body Loading”. Alternatively, the dome may be charged from an external source – we call this “Mono Loading”. The external source can also be used to set the outlet pressure remotely. Provision can be made for either or both (“Dual Loading”) methods. The outlet pressure is substantially unaffected by flow rate or by changes in the inlet pressure. Additional outlet ports are provided on RH20 and RH30 for convenient direct fitting of our RS type relief valves.
