Abstract
A supply manifold for a hydronic heating or cooling system has a housing a plurality of valves disposed on respective outlets of the housing in a linear arrangement. Each outlet is adapted to connect to a conduit for delivering the liquid to a zone. Each valve controls a flow of the heating or cooling liquid into each respective conduit. The supply manifold has a single actuator for individually actuating one of the valves. A first displacement mechanism, e.g. a screw drive power by an electric motor, displaces the actuator along a longitudinal axis parallel to the linear arrangement of the valves to thereby access any one of the valves. A second displacement mechanism, e.g. a solenoid, displaces the actuator orthogonally to the longitudinal axis to thereby cause engagement or disengagement of the actuator with a selected one of the valves for opening or closing.
