Abstract
A sequencing valve and associated hydronic system are provided. The valve has first and second ports, which can be connected to a heat exchange device, and the valve is configured to selectively provide multiple fluids to the heat exchange device. For example, the valve can selectively connect hot and cold water supplies to the heat exchanger so that the heat exchanger can be used alternately to heat and cool air for a refrigeration system. The valve can include check valves that are adjusted by rotatable cams for controlling the flow of fluids into and out of the ports. Each cam can be mounted on a rotatable shaft so that the cams rotate to adjust the check valves between open and closed positions.
