Abstract
A valve for a subsea pressure canister for controlling a fluid flow includes a valve body having a passage extending in a longitudinal direction. At an inner surface of the passage, a valve seat, a sealing section, and a threaded section are formed. A stem is arranged within the passage and movable in the longitudinal direction between a closed position and an open position. The stem includes a valve member to provide a sealing between the valve seat and the valve member in the closed position. A seal is arranged between an outer circumferential surface of the stem and the sealing section. An actuator device includes a threaded section engaged with the threaded section of the passage. The actuator device includes a coupling element for coupling the actuator device to the stem to urge the stem in the longitudinal direction upon the longitudinal movement of the actuator device.
