Abstract
A valve is disclosed. The valve has a magnetic actuator, which is provided with a sleeve extending along an axis, with a movable core made of ferromagnetic material and axially guided by the inner surface of the sleeve, and with a magnetic stator arranged in a fixed position around the sleeve. The stator has a housing made of ferromagnetic material, a coil facing the external surface of the sleeve, and two magnets, which are aligned with the coil, are arranged on opposite axial sides of the coil, and have a same pole aimed against each other. The valve has a conduit with a valve seat axially facing a plug member, which is coaxial and fixed with respect to an end portion of the core, so as to open and close the valve seat. The core has at least one passage allowing a fluid to flow through the core.
