Three-way zone valve 800-714

The Legend Valve 800-714 is a three-way zone valve built for hydronic heating systems. It uses a 3/4-inch sweat connection and provides a 5.4 CV flow factor for water flow control.

Installers needing a sweat-fit diverter

This valve suits installers who need a three-way diverter with a sweat connection for closed-loop heating. It is not for technicians who require a threaded or press-fit end connection, or a two-way valve body.

5.4 CV flow factor

The 5.4 CV factor determines the flow capacity through the valve. Match this value to the system design requirements to ensure correct water flow and temperature control.

Questions about this item

Does the 800-714 zone valve generate noticeable heat or noise during continuous operation?

The valve body has no motor or electronics, so it adds no measurable heat and runs silently; only the separate actuator consumes power.

What plumbing parts are required to install the 3/4" sweat connections?

You need 3/4" copper tubing, solder and flux to make the sweat joints.

Will the 5.4 CV flow coefficient work with my existing zone piping and pump?

The 5.4 CV rating matches standard residential zone circuits; verify your pump head and pipe sizing against that value.
