Three-way zone valve 1-1/4" sweat

The Legend Valve 800-716 is a three-way zone valve with a 1-1/4 inch sweat connection and a 9.8 CV factor. It is designed for hydronic heating and cooling systems that require flow diversion or mixing between circuits. Installers use it to control zone distribution in residential and light commercial applications. The valve body is new and ships directly from the manufacturer.

Sustained flow control performance

Under continuous operation the valve maintains its rated 9.8 CV factor to deliver consistent flow modulation across the three ports. The three-way configuration allows reliable diverting or mixing during long heating cycles without pressure drop deviation. Internal components are built to tolerate repeated actuation over extended seasons. No short-term burst rating is published for this model.

Thermal and power characteristics

The valve handles typical hydronic fluid temperatures encountered in closed-loop heating and chilled-water systems. Actuation power draw is limited to the low-voltage control signal required by the chosen actuator. No fan or active cooling is present so operational noise is negligible. California Proposition 65 warnings apply for chemicals known to cause cancer and reproductive harm.

Questions about this item

Does the 800-716 valve generate noticeable heat or noise when powered continuously?

The motorised actuator runs on low-voltage AC and produces minimal warmth; no fan or pump is inside the valve body itself.

What piping and control items must already be on site for the 1-1/4" sweat connection and 9.8 CV flow rating?

You need 1-1/4" copper tubing, flux, lead-free solder, a torch, and a compatible low-voltage thermostat or zone controller wired to the actuator.

Will the 800-716 work with an older boiler that uses a standing-pilot gas valve and mechanical aquastat?

Yes — the valve only requires a standard low-voltage signal, so it can be driven by the existing aquastat contacts or a modern replacement controller.
