The safety electrovalve (1) with manual reset comprises a valve body (2), a shutter device, a shutter spring (26) and an abutment element (28) thermally yielding for making a thermal protection system. Moreover, the open/closed status of the shutter device can be displayed. Finally, it is possible to obtain a normally open or normally closed electrovalve only by suitably rotating the abutment element in the electrovalve assembly step. |
