Abstract
A gas venting valve arrangement is disclosed, the gas venting valve arrangement comprising a valve housing having an inlet in a bottom region of the housing connectable to a fluid flow to be passing through a subsea pump or compressor, and an outlet for gas accumulating in a top region of the housing. A valve mechanism operating a movable valve body at the outlet' between open and closed positions. A floater in the housing actuating the, valve mechanism, wherein the floater is acted upon by a force means which is dimensioned to increase buoyancy of the floater with respect to a liquid phase of the fluid accumulating in a bottom region of the housing.
