Solenoid valve with BRASS and STAINLESS STEEL 316 body.
3 ways Normally closed and universal.
Seals: Buna (NBR), Viton (FKM), EPDM, Ruby.
Coils: Standard, Bistable, Explosion proof
Port size 1/8", 1/4" and socket.
Fluid temperature up to 180°C.
The 3 ways direct acting range is suitable for actuators control, and in application directly in contact with the process fluid (ais, gas compatible with valve materials, water, steam, liquids compatible with materials). THe class H coils permit to work up to 180°C and bistable coils allow low energy consumption for portable applications or where temperature increase must be avoid. The explosion proof coils works in potential explosive environments.

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.
