The Danfoss threaded union is an original accessory designed exclusively for AB-QM DN 15 valves. It is used to provide a secure, leak-tight connection between the valve and the pipework by means of an R ½ male thread. The union is an essential component when installing an AB-QM valve in heating or cooling systems where a threaded connection is required without welding or soldering.

AB-QM valves are pressure-independent balancing and control valves (PICV) from Danfoss, designed for the hydraulic balancing of heating and cooling systems. Together with the valve, the threaded union forms a complete and reliable valve assembly.

• Original Danfoss accessory ensuring full compatibility with the AB-QM DN 15 valve
• R ½ male thread for quick and easy connection to pipework
• Rigid, leak-tight design suitable for heating and cooling systems
• Simple and fast installation without the need for welding or soldering
• Sold as 1 piece

Application

The union is intended for installing the AB-QM DN 15 valve in pipework systems with an R ½ male pipe thread. Typical applications include hydraulic balancing systems in buildings, fan coil circuits, chilled ceilings, and other heating or cooling systems equipped with Danfoss PICV valves.
