ABSTRACT:
A multiple-section, multiple-position switching valve and a hydraulic powered valve actuator for controlling subsea well equipment, such as valve operators, connectors and other hydraulically actuated devices, with only two hydraulic pressure source lines from the surface to the subsea location of such well equipment. The switching valve includes a plurality of readily removable and replaceable valve sections, each having a unique combination of valve portings, which sections can be connected end to end to obtain a switching system having a predetermined matrix of switching control. The valve actuator moves the switching valve in a first direction through a sequence of distinct positions, and then reverses and moves the switching valve in the opposite direction through the same distinct positions. The switching valve includes a position indicating valve section and circuitry which are incorporated into the design and connected to one of the hydraulic pressure source lines to give a surface indication of the valve's position and that of the subsea actuator.
