Pressure-independent regulating valve AB-QM, DN15 with measuring connections, Male thread. Nominal flow rate 650 l/h 003Z8201

Danfoss AB-QM 003Z8201 is a pressure-independent control valve (PICV) designed for precise flow control in heating and cooling systems. It is ideal for systems with fan coil units, chilled beams and other terminal units where stability and accuracy of regulation are crucial. Thanks to its design, this valve ensures optimal operating conditions of the installation regardless of pressure fluctuations in the network.

Characteristics and application

AB-QM is an advanced solution for professionals and users who appreciate energy efficiency and comfort. Its main task is to maintain the set flow rate, which translates into even distribution of heat or cold throughout the system. Equipped with measuring connections, it allows easy measurement and control of operating parameters. Metric external thread ensures universal mounting in various installations. Pressure class PN 25 guarantees safety and reliability even in difficult operating conditions.

The AB-QM 4.0 valve is distinguished by a unique authority of 100%, which means the highest regulation performance in its class. The ability to pre-set the flow rate in the range of 10-100% allows for precise adaptation to the specific needs of each heating or cooling circuit. It is compatible with the Danfoss NovoCon S digital actuator, which further increases its functionality and control options.

Construction and technical parameters

The valve is made of high-quality DZR brass (CW 602N), which ensures its durability and corrosion resistance. It has an actuator connection M30 x 1.5 and a pitch of 4 mm. Its nominal diameter is DN15 (1/2 inch), and the nominal flow rate is 650 l/h (0.65 m³/h). It can be used with liquids with a temperature from -10°C to 95°C. The valve height is 79 mm, and its weight with packaging is approximately 0.59 kg.
