Pressure-independent regulating valve AB-QM, DN20 without measuring connections, Male thread. Nominal flow rate 1100 l/h 003Z8223

The AB-QM valve is a pressure-independent flow regulator designed for precise control in heating and cooling systems. It is ideally suited for applications such as fan coil units and chilled beams, where stability and regulation efficiency are crucial. Its construction based on a unique 100% authority ensures the highest performance in its class.

This valve is particularly appreciated by installers for its ease of configuration and reliable operation. It allows for pre-setting the flow rate in the range of 10-100%, which significantly simplifies adaptation to specific installation needs. For the end user, this means thermal comfort and optimized energy consumption.

Characteristics and application

AB-QM is a regulating valve designed for liquids, characterized by a pressure class of PN 25. It has a metric external thread, which facilitates installation in standard installations. The actuator connection with dimensions of M30 x 1.5 ensures compatibility with the Danfoss NovoCon S digital actuator, enabling precise flow control. The stroke length is 4 mm, allowing for accurate adjustment to system requirements.

The nominal valve diameter is DN 20, and its height is 75 mm. The nominal flow rate of 1100 l/h guarantees adequate performance in typical applications. The material of the valve is varied – it is worth paying attention to the material specification when choosing the appropriate model for a specific medium.

Advantages and benefits

• Precise regulation: Thanks to its 100% authority, it ensures a stable flow regardless of pressure changes in the installation.
• Versatility: The ability to pre-set the flow rate in the range of 10-100% makes it easy to adapt to different applications.
• Durability and reliability: Solid construction guarantees a long service life and minimizes the risk of failure.
• Compatibility: Cooperation with the NovoCon S actuator enables advanced control and integration with building automation systems.
• Cost optimization: Precise flow regulation translates into energy savings and reduced operating costs of the heating or cooling system.
