A valve includes a housing having an inlet ( 3 ), an outlet ( 1 ) and a movable sealing member ( 2 ) which allows the inlet ( 3 ) and the outlet ( 1 ) to be connected in fluid communication with each other, the sealing member ( 2 ) having associated therewith effective areas ( 4 b) to which pressure can be applied, and sealing areas ( 4 ), and the sealing member ( 2 ) further having associated therewith a sealing seat ( 4 a) for sealing the inlet ( 3 ) from the outlet ( 1 ). In order to provide a valve by which pressure can be relieved in a very short time, the sealing member ( 2 ) has associated therewith a conduit ( 2 a) by which the inlet ( 3 ) and the outlet ( 1 ) can be connected in fluid communication with each other when the sealing member ( 2 ) rests on the sealing seat ( 4 a).
