Product Description

Danfoss AB-QM ANSI 4" — pressure-independent balancing and control valve (PICV) for a ANSI 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 M30 x 1.5 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 (A48 No. 35A) body,, 165 gal/min nominal flow, 4 psi to 60 psi control differential, stroke 15 mm, media temperature 15 °F to 250 °F, supplied with test plugs. OEM P/N 003Z0785. EAN 5710104034225. Technical data quoted verbatim from store.danfoss.com (code 003Z0785).

Compatibility & Fitment

Danfoss AB-QM PICV for 4" heating or cooling circuits. Size the valve by the branch design flow (165 gal/min nominal flow at 100% presetting here) and confirm the connection type (ANSI flange) and pressure class () match the pipework. The valve is driven by a matching Danfoss actuator (thermal, ABNM/AMV/AME on/off or modulating) fitted to the M30 x 1.5 actuator connection — the actuator is ordered separately. ANSI variant: imperial connection, °F media rating and psi differential.
