With a 1/2″ ODS connection, it fits into copper piping networks and works with compatible actuators to regulate flow. Commonly installed in residential and light commercial systems, it enables zone-based temperature management. Within the system, this valve body serves as a flow control point, supporting balanced circulation and efficient operation across multiple zones.
