Coaxial and pressure-balanced structured, direct or externally-controlled electromagnetic valve e.g. 3/2-way valve, has coil actuated over electronics that evaluates position of magnet based on electrical data

摘要

The valve has a magnetic coil actuated over an electronics that evaluates a position of a magnet based on electrical data. The evaluation electronics operates the valve with an input variable e.g. current and voltage, and holds the valve in a desired position. The closing operation of the valve is regulated such that movement of the valve is lowered immediately to fraction of the preceding closing speed before reaching the closed position. The control of the magnetic coil is enabled with a digital control signal.
