balancing cartridge

Outlet

The balancing cartridge modulates the valve to control temperature to

the knob set point. At the set point, the valve is at minimum position.

This allows hot water supplied by the circulator to be distributed to the

other branches resulting in effective automatic thermal balancing. The

automatic response allows each hot water branch to quickly deliver hot

water to each xture.
