Total isolation diverter valve

Total isolation diverter valve comprising a valve body having a main fluid inlet conduit for inletting a fluid, a first fluid outlet conduit for outletting the fluid and at least one second fluid outlet conduit for outletting the fluid, wherein the first fluid outlet conduit is provided with a first fluid adhesion inner surface and the second fluid outlet conduit is provided with a second fluid adhesion inner surface, a connection channel interposed between the main fluid inlet conduit and said first and second fluid outlet conduits, the connection channel including at least one perturbation device configured so as to cause a deviation of the fluid flow from said first fluid outlet conduit to said second fluid outlet conduit or vice-versa by exploiting a physical effect called Coanda effect, the perturbation device comprising:

• a first perturbation orifice adjacent to said first fluid adhesion inner surface;
• and
• at least one opening/closing element configured to open and sealingly close the first perturbation orifice,
• the perturbation device being provided with an actuator arranged outside the valve body and comprising a wire manufactured with a shape memory alloy, said wire being configured to deform when an electric current is passed therethrough and being configured to move a plunger operatively connected to said at least one opening/closing element, the movement of said plunger determining the opening of said at least one opening/closing element.
