To overcome problems concerning the sticking of the check plate in a combined check and control valve, a stop is provided on the valve rod or a guide element in the vicinity of the valve rod, whose distance to the limiting element is smaller than the maximum stroke and larger than the nominal stroke of the limiting element. Thus, it is achieved that the check plate is released from the valve seat by means of the stop, when the valve rod is displaced to the maximum.
