Abstract

The valve is formed in a valve body housing a first path portion, a second path portion, and an coupling zone between the first and second path portions. A shutter is arranged in the coupling zone and has a shutting portion of ferromagnetic material that is deformable under the action of an external magnetic field between an undeformed position, wherein the shutter closes the coupling zone, and a deformed position, wherein the shutter at least partially frees the coupling zone. The shutting portion of the shutter is formed by a rubber membrane incorporating particles, for example of ferrite particles.
