Description
The direct action lifting armature solenoid valve type 0256 can be used in a versatile way. In the de-energized state, the valve is closed due to spring force. When shifting, the Kern is tightened against a spring; the valve opens. The valve is preferably suitable for locking, dosing, filling and ventilating for a wide range of uses with neutral media.
