Danfoss AB-QM ANSI 3" high-flow pressure-independent balancing & control valve ANSI flange

Danfoss AB-QM ANSI 3" (high-flow) — pressure-independent balancing and control valve (PICV) with 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 separate manual balancing valve or commissioning flow-measurement is required. Grey cast iron (A48 No. 35A) body,, 176 gal/min nominal flow, 9 psi to 60 psi control differential, stroke 15 mm, media temperature 15 °F to 250 °F, supplied with test plugs. OEM P/N 003Z0984. EAN 5714279008913. Technical data quoted verbatim from store.danfoss.com (code 003Z0984).
