Threaded connector (AB-QM, ASV), DN 20 003Z0233

Threaded connector for AB-QM valves – a reliable connection in heating and cooling systems.

This threaded connector, with a nominal diameter of DN 20, is a dedicated connecting element for regulating and balancing valves of the AB-QM series from Danfoss. It provides a tight and durable connection in installations where precise flow control is crucial. Its use allows for easy integration of valves with existing pipes and installation elements.

The connector is compatible with both threaded and flanged versions of AB-QM valves, offering flexibility in design and modernization of systems. Made of high-quality materials, it guarantees corrosion resistance and long-term reliability. Thanks to this, installers can be sure of the solidity of the work performed, and end-users – trouble-free operation of the system for many years.

Wide application and compatibility

The connector with catalog number 003Z0233 finds its application in various heating and cooling systems, including:

• Central heating systems: Enables precise regulation of the flow of hot water in individual heating circuits.
• Air conditioning systems: Allows for effective control of the refrigerant flow.
• Industrial installations: Works well in applications requiring precise liquid dosing.
• Systems with variable or constant flow: Ensures optimal operation regardless of operating conditions.

Additionally, the connector is compatible with a wide range of Danfoss accessories, such as adapters, stem heaters, and stroke limiters, allowing you to adapt the system to individual investor needs. It can also be combined with electric actuators for automation of the regulation process.

Construction and materials

The connector is made of DZR brass (CuZn36Pb2As - CW 602N), which ensures its high corrosion resistance and mechanical strength. This material is widely used in water and heating installation elements due to its anti-corrosion properties and compliance with sanitary standards. The external thread compliant with ISO 228/1 standard guarantees a tight connection with other installation elements. The connector design is designed to ensure minimal pressure drop of the flowing liquid, which translates into energy savings and efficient system operation.
