Danfoss AB-QM DN 200 high-flow pressure-independent balancing & control valve flange (003Z0737)

Danfoss AB-QM DN 200 (high-flow) — pressure-independent balancing and control valve (PICV) for a flange connection. A single AB-QM valve combines three functions in one body: an automatic flow limiter that holds the set flow constant regardless of pressure fluctuations elsewhere in the system, a control valve (operated by a Danfoss thermal or modulating actuator on the Danfoss standard connection), and a manual shut-off. Presetting fixes the maximum flow so the branch is inherently balanced — no manual balancing valve or commissioning flow-measurement is required. Grey cast iron EN-GJL-250 (GG-25) body, PN 16, 410 m³/h nominal flow, 60 KPa to 800 KPa control differential, stroke 36 mm, media temperature -10 °C to 120 °C, supplied without test plugs. OEM P/N 003Z0737. EAN 5715255139508. Technical data quoted verbatim from store.danfoss.com (code 003Z0737).
