Safety valves; Equalising valves, e.g. pressure relief valves with a fracturing member, e.g. fracturing diaphragm, glass, fusible joint the fracturing member being a generally elongated member, e.g. rod or wire, which is directly connected to a movable valve member, the breaking or buckling of the elongated member allowing the valve member to move to a closed or open position
