Abstract
A double safety valve includes a valve body having an inlet opening for a pressurized fluid and an outlet opening, both communicating with connected chambers within the valve body which connection may be shut-off by shutters activated by corresponding electric coils. The shutters are placed along a common longitudinal axis opposite to each other, and activated independently for shutting off the connections between the chambers and the openings in favour of the fluid flow, that is to say pressurized fluid acting on the shutters so that the shut-off is maintained when the shutters are deactivated. Each shutter is kept in a shut-off position also by the fluid coming from the inlet openings acting on a first end of the shutter inside the corresponding electric coil.
