Abstract
The normally closed, two-position, three-way latching hydroseal valve can be used in subsea applications in connection with the production of oil and natural gas. The latching hydroseal valve can be operated by remote pilot valves to open and close the latching hydroseal valve or in an alternative embodiment attached solenoid pilot valves can be used. The seal carrier has pistons of different diameters to latch the valve open after the pilot fluid is vented to atmosphere. The main seal assembly includes a bi-directional seal.
