The continual need of SIRAI^® to find adequate solutions to its requirements of encapsulated coils for solenoid valves is the main reason which has determined the origin and development of the coil  division.

The experience and know-how acquired in the context of this dynamic reality and the high qualitative level have successively led SIRAI^® to keep up with market requests.  The incentives which have been derived and the necessity to confront various applicative problems have contributed during the course of the years to a natural expansion of the product range, developing alongside encapsulated coils, linear, holding and locking solenoids.

The commitment in all phases of manufacture, from the buying of the best material up to the rigorous final controls and the maximum flexibility concerning client relations are a further guarantee of products at the same elevated standards which characterise all SIRAI^® productions.
