High pressure high temperature (HPHT) well tool control system and method
Methods and apparatus are disclosed. The problems of damage and failure of solenoid valves in high pressure high temperature environments and the problem of difficult repair of solenoid valves are addressed through reduction of the possibility of damage to the ball seat and/or seals and through a modular design to increase the ease of repair and adjustment in the event repair is needed.
