Danfoss AB-QM Pressure Independent Control Valves (PICV)

The Danfoss AB-QM is a top-tier Pressure Independent Control Valve designed for precise flow regulation in HVAC systems. Engineered with an integrated differential pressure regulator and built-in flow limiter, it delivers 100% valve authority, eliminating the need for complex Cv calculations during sizing.

Key Advantages

• Simple selection & setup — choose by design flow; adjustable from 10–100% without tools
• Optimal performance — maintains correct coil flow, enhancing chiller and boiler efficiency while reducing pumping costs
• Clog-resistant and robust — premium materials resist scaling and particle buildup
• Broad size range — available from DN 15–250, PN25 rating, with threaded or flanged ends and test-plug options
• Enhanced diagnostics with AB-QM 4.0 — supports flow measurement (PFM 1000) and IoT-ready digital actuators

Whether for new construction or retrofit projects, Danfoss AB-QM valves provide the ideal solution for reliable and energy-efficient HVAC flow control.

Actuator Options

• Thermal & electric actuators (TWA-Q, AMV/AME) — available in 0–10 V or on/off control
• NovoCon® digital actuators (S, M, L, XL) — smart modulating actuators with BACnet / Modbus, remote monitoring, and real-time flow data for full BMS integration
