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
actuators
