Proportional valve for controlling fluid flow, particularly for use in area of hydraulics or pneumatics, comprises permanent magnet and electric coil, which is relatively moved corresponding to current strength applied on electric coil

摘要

The proportional valve comprises a permanent magnet (12) and an electric coil (4), which is relatively moved corresponding to a current strength applied on the electric coil. A shut-off body is provided, which forms the permanent magnet, which is relatively moved to a valve seat (16) by energizing the coil. A sealing element (14) is provided, which is arranged at the valve seat facing towards the surface of the permanent magnet or at the valve seat.
