Abstract
A stemless ball valve comprising a first flange, second flange, ball, inner magnetic cartridge, outer magnetic cartridge, and planetary gear assembly. The inner magnetic cartridge is situated inside of the outer magnetic cartridge, and the inner and outer magnetic cartridges actuate the valve. The planetary gear assembly is situated between the inner magnetic cartridge and the ball. The planetary gear assembly comprises one or more planetary gear phases, each planetary gear phase comprising a step-down gear. Each planetary gear phase comprises one or more planetary gears that engage with the inner teeth of the outer ring of the planetary gear assembly and with a step-down gear. The invention further comprises a pressure equalization system comprising inner and outer equalization tubes, a piston situated between the inner and outer equalization tubes, and either a piston spring or spring washer stack that biases the piston in the direction of the clean oil.
