Abstract

Valves. At least some of the example valves include: a valve body; a valve housing; and a piston that defines a proximal end and a distal end, the piston disposed in a piston bore of the valve housing. The valve defines a closed orientation by a first rotational orientation of the valve housing relative to the valve body, and the valve defines an open orientation by a second rotational orientation of the valve housing distinct from the first rotational orientation.
