A pressure control valve for open-loop or closed-loop control of a pressure of a compressed fluid in a pilot pressure chamber includes a valve housing with at least one inlet and at least one outlet, a wall section fixedly connected with the valve housing and having a first passage channel and a first throughbore, through which the compressed fluid can flow, and forms a first valve seat. The pressure control valve also includes a tappet and first and second sealing elements. The tappet is mounted in the valve housing and movable along a longitudinal axis by an energizable actuation device. The first sealing element is mounted so as to be movable along the longitudinal axis in the valve housing and is biased by means of a first spring into a closure position in which the first sealing element bears against the first valve seat and closes the first through-bore.
