Abstract
A fluid regulator includes a poppet valve within a flow path that selectively allows a flow of fluid to move from an inlet to an outlet. A threaded regulating interface adjusts a spring tension exerted toward the poppet valve and defines a regulated flow of the fluid through the flow path. A fluid purge mechanism is positioned within the threaded regulating interface. The fluid purge mechanism operates along a rotational axis of the threaded regulating interface and adjusts a boundary of the flow path and manipulates the poppet valve to a maximum operating position to define a purging flow of the fluid. A programmable logic controller cooperates with the powered actuator and a pressure sensor to define a closed-loop interface that adjusts the regulated flow of the fluid through the flow path.
