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.
