Description
The Siemens Building Technology 254-01119 2-Way Valve Assembly is a two-port flow-control system with a normally open position for regulating fluid movement through connected piping. A 24 VAC actuator signal changes the valve state according to the control command, allowing the assembly to regulate circulation through the served circuit. The 1/2″ NPT connections provide the specified threaded interface, while the 1.0 Cv rating identifies its flow coefficient in HVAC systems, this valve assembly operates as a controlled point within hydronic piping, responding to automation signals that determine when fluid passage is permitted.
