Legend Valve 800-715 Zone Valve
This three-way zone valve carries the Legend Valve brand and is supplied in new condition. It is designed for hydronic heating systems that require flow diversion between two circuits. The sweat connection allows direct soldering to copper piping during installation. A 6.7 CV factor indicates the flow capacity through the valve body.
Installers needing a three-way diverting valve
The unit suits professionals assembling or servicing hydronic zones where a single inlet must be directed to one of two outlets. It is not intended for two-way on-off service, so buyers who need a simple shut-off valve should look at a different design. Systems that call for a threaded or flanged connection cannot use this sweat model without adapters. The California Proposition 65 notice also means installers in regulated environments must handle the product accordingly.
6.7 CV flow factor
The CV value of 6.7 is the primary figure that determines whether the valve can deliver the required flow at an acceptable pressure drop. Engineers should compare this number against the calculated load of the zone it will serve. If the system demands a higher or lower CV, a different valve body must be selected.

Questions about this item
What pipe size and connection type does the 1" sweat valve require for installation?
The valve uses a 1" sweat connection so copper tubing of the same nominal size must be soldered in place.
Will the 6.7 CV factor handle the flow demand of an older zone circuit I plan to keep?
The 6.7 CV rating indicates the flow capacity; compare it with the design flow of the existing circuit to confirm compatibility.
How can I verify the 3-way valve is diverting flow correctly after I solder it in?
Operate the actuator and check that supply water routes to the intended port while the other port closes, confirming proper 3-way function.
