Multifunctional automatic valve AB-QM with measuring connections DN32 003Z1215

Multifunctional automatic valve – precision and comfort in heating and cooling systems

The AB-QM automatic valve is an advanced solution for central heating and chilled water installations, combining flow regulation and automatic balancing functions. Its diaphragm-based design ensures independence from pressure fluctuations in the installation, which translates to stable and efficient operation of the entire system. The valve is adapted to work with both ON/OFF and modulating actuators, providing flexibility in control selection.

The AB-QM valve with measuring connections (DN32) allows for accurate measurement of flow parameters, which is particularly important during commissioning and optimization of the installation. Made of dezincification-resistant brass (DZR) guarantees durability and corrosion resistance, even in harsh operating conditions. The possibility of using it in installations with glycol expands its range of applications.

Construction and principle of operation

The heart of the AB-QM valve is a differential pressure regulator, which maintains a constant pressure drop regardless of flow changes. Thanks to this, the valve provides precise regulation and limitation of the maximum flow to a set value, adapted to the performance of end devices. The linear control characteristic ensures a smooth change in flow throughout the valve's operating range. Measurement connections allow easy reading of installation operating parameters, which facilitates diagnostics and system optimization.

The AB-QM valve is compatible with popular actuators with an M30 x 1.5 connection, which facilitates its integration with existing control systems. Robust construction and high-quality materials guarantee long-lasting and trouble-free operation of the device.
