Schneider Electric (Erie) VS2223 2-Way 2-Position Zone Valve 1/2" NPT 3.5Cv Steam

The Schneider Electric (Erie) VS2223 2-Way 2-Position Zone Valve Steam regulates steam flow by moving an internal valve element between fully open and fully closed positions. In HVAC systems, its actuator responds to the control signal and positions the valve to permit or block steam passage through the two-port body. The 1/2" NPT connections provide threaded interfaces for compatible steam piping, while the 3.5Cv rating measures the valve's flow capacity under specified conditions. Installed in the steam distribution line, the two-position arrangement controls steam delivery to the connected heating zone. This operation establishes discrete flow control for the associated steam circuit.
