Pressure-independent regulating valve AB-QM, DN20 with measuring connections, Male thread. Nominal flow rate 1100 l/h 003Z8203

The AB-QM valve is a pressure-independent flow regulator designed for precise control in heating and cooling systems. It is ideally suited for use with fan coil units, chilled beams and other terminal units where stability and accuracy are critical. Thanks to its unique 100% authority, the valve ensures optimal control performance, minimizing energy losses and providing thermal comfort.

Characteristics and application

The AB-QM valve is designed to work with liquids, and its pressure class PN 25 guarantees safety and reliability in installations with increased pressure. The metric external thread (M30 x 1.5) facilitates installation and integration with existing systems. The nominal flow rate of 1100 l/h (1.1 m³/h) makes it suitable for a variety of applications. The stroke length of 4 mm allows for precise adjustment of the flow to current needs.

Advantages for the installer and user

• Precise regulation: Independence from the working pressure ensures a stable flow, regardless of changes in the installation. This translates into better user comfort and energy savings.
• Durability and reliability: The valve made of high-quality materials guarantees a long service life and minimizes the risk of failure.
• Versatility: The ability to pre-set in the range of 10-100% flow allows the valve to be adapted to the specific requirements of a given system.
• Compatibility: The valve is compatible with the Danfoss NovoCon S digital actuator, enabling integration with advanced building management systems.
• Easy installation: The metric external thread facilitates quick and trouble-free installation in existing installations.
• Optimal price-quality ratio: The AB-QM valve offers high performance at a competitive price, making it an attractive solution for a wide range of customers.
