Two-Way Zone Valve with End Switch

The Legend Valve 800-706 is a normally closed two-way zone valve designed for hydronic heating systems. It provides on-off flow control for individual zones and includes an integrated end switch for equipment interlocking. This component suits HVAC technicians and installers assembling or servicing zone-based distribution networks.

11.7 CV Flow Factor and Power Operation

The valve body delivers an 11.7 CV factor to accommodate high-flow zone requirements. It operates on standard low-voltage control circuits typical for zone valve actuators. Normal operation draws minimal power while the end switch activates auxiliary equipment only when the valve reaches the fully open position.

Sweat Connection and California Compliance

The valve features 1-1/4 inch sweat connections for copper piping installation using standard brazing techniques. No special tools beyond normal pipe-fitting equipment are required for the joint. The product carries California Proposition 65 warnings for chemicals known to cause cancer and reproductive harm.

Questions about this item

How is the 800-706 2-way zone valve installed, and what step do people get wrong?

The valve body is soldered into 1-1/4" copper piping; the common error is overheating the body during sweating, which can damage the internal seals and the end-switch wiring.

What maintenance or replacement will the 11.7 CV zone valve need later?

The motor-head assembly and end-switch mechanism are the wear items; they can be swapped without cutting pipe by removing the retaining screws on the valve body.

What limit shows up first on the 800-706 valve under sustained use?

Continuous high-temperature cycling stresses the motor actuator and end-switch contacts, so actuator fatigue or contact wear typically appears before the valve seat itself fails.
