摘要： A subsea valve actuator is disclosed, comprising an override shaft (6) reaching from inside a fluid filled and pressure compensated actuator housing (1) to the exterior thereof via a bearing and sealing arrangement (7), wherein a visual valve position indicator (14) is arranged exterior to the actuator housing. The visual indicator (14) is pivotally mounted to the override shaft and guided non-rotatably to be forced in axial displacement on the override shaft when the override shaft is rotated, wherein the mounting of the visual indicator (14) on the override shaft (6) is encased in a fluid filled, pressure compensated indicator mounting enclosure (19) surrounding the override shaft (6) in sealing (26) relation outside of the actuator housing (1).

摘要： A subsea arrangement comprising an external casing and a pressure equalizing valve for equalization of the fluid pressure in an internal space of the casing. The pressure equalizing valve is provided with a valve body including a base section displaceably received in an opening provided in the casing; and a valve member secured to the base section and arranged inside the casing, the valve member facing a valve seat surrounding said opening. The valve body is displaceable upwards, under the effect of an external fluid pressure, from a resting position, in which the valve member prevents fluid flow into and out of said internal space, to a raised position, in which the valve member allows fluid flow from the surroundings into said internal space for equalization of the fluid pressure therein when the subsea arrangement is lowered into the sea.
