The Spiral Valve is a piece of Mechanist technology, though it may have origins with the Hammerites. The piston connects to it, and the valve connects to the step gear.[1] It is not seen in-game.

Real-world spiral valves are not mechanical, but provide a biological function, such as the gallbaldder in humans, and the intestines in sharks.[2]
