Zone valves

Reliable terminal unit control.

Siemens zone valves have a stroke valve design for on/off or basic modulating control to ensure HVAC hydronic systems deliver reliable comfort. Feature direct-coupled technology for quick connection of the valve body and actuator without tools.

Siemens Zone valves are available in ½- to 1-inch line sizes with Cv ranging from 1.0 to 7.0. These valves can control hot and chilled water, with up to 50% glycol, over a temperature range of 35° F to 230° F. On/off fail-safe and floating or modulating fail-in-place actuators are available.
