Description.......

This type of electromagnets has been expressly studied and realized for the control of oleodynamic valves.
These appliances are based on the same principle as the one-stroke electromagnets. The travel takes places, depending on the control, from the central position to one of the two end-of-stroke positions, and returns by means of external forces, normally a spring, after
de-energizing in the central position, i.e. the starting position for both directions.
The assembly position is irrelevant, but the power outlet must be set in the axial sense only, otherwise, in the presence of a side load, a considerable wear of the cylinder in which the keeper slides would occur.
These appliances consist of an electrical part and a waterproof mechanical part. The electrical part is costituted by a coil encapsulated with two windings, having the connector electric contacts complying with DIN 43650.
