The threaded union is an original spare part and accessory intended exclusively for Danfoss AB-QM valves. The AB-QM valve is a pressure-independent balancing and control valve (PICV) with an integrated differential pressure controller, ensuring precise flow limitation regardless of pressure changes in the system.
This union with an external R 3/4 thread is used for a secure and leak-tight connection of the DN 20 valve to the pipework. It is used in heating, cooling and ventilation systems wherever the AB-QM DN 20 valve is installed as a control element for terminal units (fan coils, air handling units, induction units, radiant panels, heat exchangers, etc.).
Thanks to its precise design and compliance with ISO 228/1, the union guarantees reliable sealing even during repeated assembly and disassembly. For correct system operation, the manufacturer recommends using only original Danfoss accessories.
