The newAB-QMpressure independent control valve (PICV) from Danfoss Heating provides a perfect flow limiter and a control valve in one compact package.
The AB-QM valve can be used as a stand-alone, automatic flow limiter valve or as a combined flow limiter and control valve when fitted with a wide range of Danfoss actuators, providing accurate and stable flow. The actuators are available in several control strategies: 0-10 volt, pulse-width modulation, on/off thermal, and on/off and 0-10 volt electric actuators.
As a result, the AB-QM valve can be used in all cooling and heating applications. It’s the perfect choice for controlling terminal units such as fan-oils, water source heat pumps, chilled ceilings, and AHUs.
For installers, setting the valve is straight forward – as easy as setting a watch – and can be done without tools. This easy-setting procedure makes late changes in the design, or subsequent system modifications, simple to implement.
The valve’s authority no longer needs to be calculated because the AB-QM features a unique design that ensures 100% authority with all settings and differential pressures. This increases control quality and precision, leading to increased comfort in the building.
In addition to easy setting and increased comfort, the AB-QM ensures reduced installation and commissioning costs and increased energy savings. And the valve’s compact design makes it easy to install in areas where space is limited.
The AB-QM is available in various valve sizes ranging from 1/2 in. to 1¼ in., with sizes up to 6 in. coming soon. The AB-QM is available with NPT, solder and complete coil kit solutions.
