Differential pressure and flow controllers

Simple Affordable Comfort - Pressure independent control excellence from the global market leader for over 30 years. Discover how Danfoss AB-QM™ Pressure independent balancing control valves (PIBCVs) can improve system efficiency by eliminating overflows and increasing ΔT.

Danfoss offers a complete range of innovative solutions - ½" to 10", to meet your HVAC system's needs for optimal flow control.

KOVM mixing valve bodies are designed to maintain room temperature by controlling hot (or chilled) water flow through radiators, fans, convectors, etc. Due to the KOVM’s unique bypass design, a constant system flow is achieved regardless of the room’s heating (or cooling) requirements. Therefore system pressures and flow rates are automatically kept constant without the need for pressure controlled bypass valves.

The VMT valve is a 2-way seated valve, used primarily for heating systems. The valve can be combined with the following thermostatic elements from Danfoss: RAVK, ABV, TWA-V or RA2000 wall mount operators.

Robustly built and designed to meet the rigors of the residential, commercial and industrial sectors, a comprehensive range of Danfoss RA2000 thermostatic radiator valves is available for hot water, one-pipe steam, and two-pipe low pressure steam systems.

Thermostatic temperature controllers are used to control the flow temperature in instantaneous/storage domestic hot water and heating systems. In multi-family houses and commercial buildings, they are used for hot water systems and for return temperature limitation in district heating applications.
