摘要

The valve seat (31) is formed on a nozzle (28) and is adjustable in valve body (2). The valve body is two part with a base (23) supporting the magnetic head (3) and the nozzle. The nozzle is adjustable in the base by a thread (29, 30) and is secured against unintended turning a counter nut (32). The nozzle has an external thread (29) engaging in a threaded bore (30) in the base. The counter nut is mounted on the outer thread and adjoins an end face (33) of the base. The nozzle has a media channel on the outer thread and a channel (41) connected to the valve seat. ADVANTAGE - The valve stroke for opening and closing the valve seat is adjustable independently to compensate for tolerances without additional measures.
