A downhole system includes a safety valve system. The safety valve system includes a tubular housing having a hydraulic control chamber, and a lock-open communication sleeve within the tubular housing. The sleeve is longitudinally movable with respect to the tubular housing. The sleeve has a downhole end portion configured to abut and enact downhole movement of a flow tube. The sleeve further has a radial communication sort alignable with the hydraulic control chamber. A method of communicating and locking open the safety valve includes using the sleeve.

Communication and lock open safety valve system and method

An actuation assembly including a sleeve member having a radially outwardly extending projection and a piston having an axis, the piston operatively coupled to the projection of the sleeve member and arranged to exert an actuation force on the projection of the sleeve member for actuating the sleeve member, the actuation force positioned about radially aligned with the axis or radially outwardly from the axis.
