Abstract

A rotary valve adapter assembly comprising an adapter plate configured to attach to a rotary valve body, a torque multiplier assembly comprising one or more planetary gear subassemblies, each of which comprises a sun gear, a ring gear, and a plurality of planetary gears, a magnetic actuator assembly comprising two sets of magnetically coupled magnets, and a shaft. The magnetic actuator assembly interfaces with the torque multiplier assembly such that when the magnets of the magnetic actuator assembly rotate, they cause the sun gear of a first planetary gear subassembly to rotate and the planetary gears to walk on the ring gear. When the carrier of the first planetary gear subassembly rotates, it causes the sun gear of a second planetary gear subassembly to rotate. When the carrier of the second planetary gear subassembly rotates, the shaft also rotates, thereby causing the valve to open and close.
