Title (EN) LEAK-FREE RISING STEM VALVE WITH BALL SCREW ACTUATOR
(FR) ROBINET À TIGE MONTANTE SANS FUITES À ACTIONNEUR À VIS SPHÉRIQUE
Abstract:
(EN) A rising stem valve with a magnetic actuator having an outer and an inner magnet assembly that are magnetically coupled to each other so that the inner and outer magnet assemblies rotate together and a ball screw that is connected to the rising stem valve and that converts rotary to reciprocal motion. The inner magnetic cartridge assembly and valve body comprise a sealed lower section that is completely sealed to the outside environment.
(FR) L'invention porte sur un robinet à tige montante à actionneur magnétique ayant un ensemble aimant externe et un ensemble aimant interne qui sont magnétiquement couplés entre eux, de telle sorte que les ensembles aimant interne et externe tournent ensemble, et une vis sphérique qui est reliée au robinet à tige montante et qui convertit un mouvement rotatif en un mouvement de va-et-vient. L'ensemble cartouche magnétique interne et le corps de robinet comprennent une section inférieure hermétiquement scellée qui est complètement étanche à l'environnement extérieur.
