Abstract
A valve includes a magnetic actuation mechanism providing torque-limiting capabilities and valve stem position indication. A drive shaft of the valve is surrounded by a first annular magnetic array within a fully sealed pressure vessel. A second annular magnetic array is positioned outside of the pressure vessel and surrounds the fully sealed pressure vessel. Each of the first annular magnetic array and the second annular magnetic array include magnets having alternating polarity, allowing the first annular magnetic array and the second annular magnetic array to form a first order coupling mechanism. When the second, outside annular magnetic array is rotated, the first annular magnetic array is caused to move, actuating the valve. Importantly, the valve includes a position indication system able to determine a position of the valve stem and includes an automatic feedback mechanism for comparing an actual position of the valve with an expected position of the valve.
