ABSTRACT:
A pressure controller device includes a housing accommodating a precision pressure regulator incorporating a first diaphragm operable upon a main valve provided between an inlet and an outlet in the housing. The regulator further includes a second diaphragm operable upon a flapper-nozzle arrangement to set the pressure of the working fluid discharged through the device. The housing further includes a resiliently loaded shuttle actuable by an operating handle connected thereto and externally protruding from the housing to operate the second diaphragm and the flapper-nozzle arrangement. Manual operation of the handle, and resulting linear movement of the shuttle, effects movement of the second diaphragm and the flapper-nozzle arrangement and thus by pressure fluid to operate the first diaphragm and thus the main valve. Consequential variation in the pressure of the fluid delivered by the device is thus achieved by the shuttle overriding the operation of the diaphragms and thus the valve.
