Directional seat valve actuated by external force

摘要

A directional seat valve actuated by external force, in particular electrically or magnetically actuated, is described. The directional seat valve has an axial bore, provided in a valve housing, for accommodating at least one valve part preferably adjustable in the direction of the axial bore. A valve body, which can be displaced at least in an axial direction, is assigned to the valve part. The valve body is in a pressure-force chain with an actuating member of an actuating magnet arranged on one side of the valve housing and can be lifted from a valve seat against the force of a restoring spring which is fitted with a spring support on the other side of the valve housing. The actuating magnet is embodied in a wet type of construction, the magnet armature being arranged along a pressure-compensated valve axis in order to realize two zero positions of the valve, "currentless open" or "currentless closed" by the actuating magnet and the spring with spring support being transposed on the valve housing. In order to realize these operating positions, it is therefore not necessary to integrate additional components into the valve.
