The V5004T Kombi-QM is a Pressure Independent Control Valve (PICV). It combines a flow controller and a full stroke, full authority temperature controller in one valve. Equipped with an actuator Kombi-QM provides a full stroke modulating temperature control. It is suitable for use in variable and constant flow systems. They may be used as constant flow limiter in constant flow systems (without an actuator) or as a Pressure Independent Control Valve in variable flow systems.
V5004T Kombi-QM is typically used for balancing and temperature control of fan coil units, air handling units, chilled ceilings and one-pipe heating systems.
Automatic pressure independent balancing and control
Precise pressure independent flow performance
Highest energy saving potential due to efficient energy transfer and minimized pump speed
Integrated measuring possibility to find the optimal setpoint for the pump
Reduced movements of actuators as pressure fluctuations do not influence the required temperature
No complex calculation needed for selection
No balancing method needed for commissioning
Wide range of application
Sizes DN15 up to DN250
Various versions to support standard flow rates as well as low flow and high flow needs
Covers two functions in one valve which reduces mounting costs
