Data sheet KOVM

3-Way Mixing Valve

The Danfoss KOVM is a linear 3-way mixing

valve with a unique bypass design allowing for

constant system pressures and ﬂow rates. When

the KOVM is combined with either the RAVK

non-electric thermostatic operator or the ABV

24VAC thermo-wax actuator the linear actuation

of the valve results in the control of hot or

chilled water ﬂow to radiators, convectors, fan

coil units, etc.

Features:

Data sheet KOVM 3-Way Mixing Valve Typical Installations: The unique piping of the KOVM allow for a variety of piping arrangements for heating and cooling applications with or without bypass. Heating application with bypass controlled by thermostatic operator. When temperature is satisfied water is bypassed via port A to AB on the KOVM. Cooling application controlled via thermostatic control. As temperature rises within the room, port B is closed allowing chilled water to flow from port A to AB.
