Danfoss AB-QM Control Valve from Devex Systems

The Danfoss AB-QM is a pressure independent balancing and control valve is able to continuously optimise large HVAC systems delivering significant running cost savings. It has been a huge success in Europe, North America, the Middle East and in Asia, and has been the preferred valve specified on several projects throughout Australia including most recently the Barangaroo project in Sydney.

The AB-QM's revolutionary technology combines the compact automatic balancing valve and the control valve into one comprehensive valve structure. AB-QM offers superior temperature control and performance compared to other pressure independent control valves on the market.

The valve addresses a number of inefficiencies that are common to many large HVAC systems:

• It eliminates over-pumping throughout the system by only delivering the required flow to the terminal units
• It keeps the delta T high which maximises the efficiency of the chillers and boilers
• It provides superior control of room temperatures creating greater comfort all while consuming less energy!

The AB-QM's unique design gives it significant advantages over alternatives:

• It offers virtually 100% authority over its design pressure range
• It does this over a large range of settings
• It is not sensitive to clogging as it does not use cartridge technology
• It can be adjusted in the field which is great for the contractor should the project requirements change along the way
