Sontay has added the AB-QM series of automatic balancing valves from Danfoss Randall to its extensive range. Renowned for their quality performance, these automatic HVAC balancing valves provide Sontay customers with access to an easy to use, high quality range, proven to reduce installation and commissioning time and costs.
Danfoss Randall AB-QM valves are a new generation of versatile, multi-function valves which combine the three functions of a motorised control valve, a pressure control valve and a double regulating valve commissioning set in one device. Now available from Sontay, they can be used for balancing and controlling fan coils, chilled ceilings and air handling units and other HVAC equipment in constant flow or variable volume systems.

AB-QM valves are easy to size and set for a specific application. By fitting the standard valve with one of four different types of Danfoss actuators, they can be easily upgraded to a motorised control valve with full authority, supplying both temperature control and flow balancing in one, space-saving device. The three control functions are specifically matched to ensure optimum system performance.
