The AquaMotion AMK-ODR Aqua-on-demand crossover valve kit is a small, quiet, lead-free stainless and brass hot water recirculation valve for single pipe (multiple dead-end runs; no dedicated recirculation lines) systems.

It installs at the fixture furthest from the tank or tankless water heater (or multiple locations for large homes and buildings). It acts in conjunction with a hot water circulator pump to supply hot water on demand with the Smart Thermostatic Control 32 and smartphone app.

The ODR Valve mounts below the fixture between hot and cold supply lines. When hot water is called for using the Smart Thermostatic Control 32, the circulator forces the cooled hot water in the hot water line into the cold supply line which returns it to the water heater.

As hotter water reaches the ODR Valve it closes until a 95°F temperature is reached.
