Description
The Mars 62449 is a two-way, normally open, two-position zone valve assembly engineered for reliable hydronic heating and cooling zone control. Featuring a 1/2″ sweat connection, this valve delivers precise flow management with a 3.5 Cv flow coefficient, making it well-suited for residential and light commercial hydronic zoning applications.
Powered by a 120VAC actuator with spring return operation, the Mars 62449 automatically returns to its normally open position upon power loss — providing a fail-safe design that maintains flow in the event of a power interruption. The two-position (open/closed) control action ensures simple, dependable integration with zone control boards and thermostats.
