The present invention relates to an improved vent valve for a gas strut, and to a gas strut incorporating such a vent valve. A vent valve (1) is provided having a first passage (9,12) in a body (2) extending from one side of a valve seat (8) to a surface of the body (2) which, in use, is exposed to the interior of a gas strut, and a second passage (15) in the body (2) extending from the other side of the valve seat (8) to a body surface which, in use, is exposed to the exterior of said gas strut. A ball (18) is provided between a screw (17), threadedly engaged with the second passage (15), and the valve seat (8), whereby tightening of the screw (17) forces the ball (18) into engagement with the valve seat (8).
