Claim Text:
1. A variable pressure control system for use in a fluid delivery system, the control system comprising: a valve positioned within a fluid line and having an inlet at a first pressure and an outlet at a second pressure, the valve being operable in a range of settings between an open state and a closed state; an actuator coupled to the valve for operating the valve within the range of settings between the open state and closed state, wherein the actuator is configured for interchanging between single-action and double-action operation; a controller for controlling the actuator based on one of either the first pressure or the second pressure, wherein the controller comprises: a sensing mechanism responsive to one of either the first pressure or the second pressure; a first internal loading valve responsive to the sensing mechanism; a second internal loading valve responsive to the sensing mechanism; and a detachable interface for fluidly coupling to the actuator and configured to be adapted for single-action and double-action operation; wherein a flow path through the controller is modified by the detachable interface so as to provide for single-action or double-action operation as necessitated by the actuator.
