3-Way Mixing Valve
Application:
Ordering Information:
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:
Unique 3-way bypass design•
Linear valve actuation•
Provides constant zone or system flow•
Designed for use with RAVK/RA 2000 wall•
mount non-electric thermostatic operators
or ABV 24VAC thermo-wax electronic

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. As the temperature is met,
port B opens bypassing the emitter.
Dual application; storage tank and heating. Diverting occurs
through the storage tank when the temperature within the tank
is below the set point of the RAVK thermostatic operator, which is
mounted on the KOVM.
2-pipe Heating / Cooling application with changeover. Depending
on the temperature of the supply water to the unit, the
thermostatic mixing valve will direct the water to either the A or B
port of the KOVM.
Heating application. The KOVM and ABV 24VAC actuator assembly
is controlled via a zone controller to provide low temperature
water for the radiant application when there is a call from the
electronic thermostat.
