Abstract

See full text

A technique provides a desired control over incremental actuation of hydraulic devices. A hydraulically actuated tool is combined with a control module. The hydraulically actuated tool has an actuator piston positioned in a piston chamber and movable between operating positions. The control module comprises a hydraulic indexing circuit arranged to enable incremental movement of the actuator piston in a first direction and full stroke movement in a second direction based on hydraulic input delivered via control lines. The hydraulic indexing circuit comprises an indexing piston system and at least one check valve working in cooperation with the indexing piston system to enable the incremental and full stroke movements.
