Abstract
A downhole tool including a valve portion having a valve housing including an inner chamber and an actuation tubular. The actuation tubular includes an outer surface, an inner surface defining a flow path, an upper end, and a lower end. A first spring extends about the outer surface of the actuation tubular between the upper end and the lower end. An actuator portion is detachably connected to the actuation tubular. The actuator portion includes an actuator housing, an actuator member arranged in the actuator housing, and a second spring operatively connected to the actuator member. The actuator member includes a first end portion operatively connected to the first spring and a second end portion. The actuator portion is selected and connected to the downhole tool to establish a selected actuation force through the second spring to compress the first spring causing the actuation tubular to shift within the inner chamber.
