Abstract
A valve system of a well string may include a compensator assembly to receive a pipe fluid from piping and include a piston chamber and a piston disposed within the piston chamber that fluidly isolates a first portion from a second portion of the piston chamber. The first portion is fluidly coupled to the piping and the second portion is filled with a hydraulic fluid and coupled to one or more hydraulic lines. The piston may translate within the piston chamber such that an increase in pressure of the pipe fluid motivates the piston to translate and increase the pressure of the hydraulic fluid. The valve system may also include a mechanical actuator coupled to a hydraulic line to articulate an armature in response to a pressure differential that is based on the second pressure and a valve that opens or closes in response to articulation via the armature.
