A packless magnetically actuated valve. A driven magnet assembly is rotatably mounted inside a nonmagnetic bonnet. A drive magnet holder surrounds the bonnet and rotates thereon. The driven magnet assembly turns a stopper positioned in the main valve body between inlet and outlet passages. The bonnet is mounted for rotation and means extend between the bonnet and the driven magnet assembly such that sufficient rotation of the bonnet will cause rotation of the stopper.
