Abstract
A tubing pressure insensitive actuator system includes a housing having a bore therein. A force transmitter is sealingly moveable within the bore, the force transmitter defining with the bore two fluid chambers. One of the fluid chambers is at each longitudinal end of the force transmitter. At least two seals are sealingly positioned between the housing and the force transmitter, with one of the seals isolating one end of the force transmitter from tubing pressure and another of the seals isolating another end of the force transmitter from tubing pressure. A method is also included.
