Provided herein is a valve with a housing, a thermostatic element of which a first end part of a piston, which axially opposes the end submerged in a thermodilatable material contained in the body of the thermostatic element, is secured to the housing; a return spring; an electrical heating resistance arranged inside the second end part of the piston; electrical connection for feeding the resistance from outside the housing; and a check mechanism for controlling a flow of fluid circulating through the housing, in a direction leading from the first end part towards the second end part of the piston, and connected to the body of the thermostatic element such that the relative movements between the body and the piston, resulting from the dilation and contraction of the thermodilatable material, move the check mechanism in relation to the housing, between closed and open positions affecting the flow of fluid.
