Siemens Zone Valves and Controls are designed to regulate the flow of heating or cooling mediums to specific zones within a building, enabling precise temperature control and enhanced energy efficiency. These valves are available in various configurations, including two-way and three-way models, and are often paired with actuators for automated operation. Siemens' zone valves feature a stroke valve design for on/off or modulating control, ensuring reliable comfort delivery in hydronic systems.
