摘要:
A multicycle hydraulic control valve. A control and actuation system for a well tool includes a control valve having one or more metal-to-metal seals which open while differential pressure exists across the seals to thereby selectively connect pressure sources to an actuator to operate the well tool. Both seals may be closed while a connection between the actuator and the pressure sources is switched by the control valve. The control valve may include a member having areas formed thereon acted upon by various pressures to facilitate operation of the control valve.
