3-way solenoid valve SIRAI

In an ever increasing typology of applications, is by now necessary avoid the oxidation involves any part of plant and instrumentation.

To meet this requirement, SIRAI® has designed a new solenoid valves series, characterized by the high quality of body material, made in PPS.

Besides solving definitely the problem of oxidation, these solutions allow to reduce the limescale.

The choice of an high quality polymer, particularly resistant to chemical and physical aggressions, allows to use these valves for a wide range of fluids, including low-pressure steam. PPS, furthermore, offers a good level of tolerance to ultraviolet rays and flames exposition.


These features, together with other peculiarities of the project, make these valves the best solution for several applications, especially in the field of small sterilizing autoclaves.

Solenoid valves are available in different versions: 2/2NC, 2/2NO, 3/2, 1/8” threaded or barbed ports. Also the electrical part draw up at the same level of high quality standards.

The compact coil, with a perfect balance between power absorption and magnetic performance, is available in “F” or “H” class, also homologated according to the main international standards.
