Danfoss ASV-PV 3G DN 100 differential pressure controller 60-100 kPa flanged (003Z0645)

Danfoss ASV-PV 3G DN 100 — third-generation self-acting differential-pressure controller for automatic hydronic balancing. Installed in the return pipe of a heating or cooling circuit, it holds a constant differential pressure across the branch or terminal (paired with an ASV-BD/ASV-M/ASV-I partner valve and an impulse tube), so that two-way control-valve authority stays high and flow noise is avoided at part load. Differential-pressure setting range 60-100 kPa (factory setting 80 KPa), Kvs 76 m³/h, Grey cast iron (EN-GJL-250) body, Flange connection, PN 16, media temperature -10 °C to 120 °C, integral shut-off. OEM P/N 003Z0645. EAN 5702421558638. Also supplied under order code 003Z0649 (EAN 5710104524023), an identical DN 100 / 60-100 kPa / flanged ASV-PV 3G valve differing only in packing/order revision. Technical data quoted verbatim from store.danfoss.com (code 003Z0645).

Compatibility

Danfoss ASV-PV 3G differential-pressure controller for DN 100 circuits. The valve maintains a set differential pressure and is used with a matching ASV-BD/ASV-M/ASV-I partner (manual balancing / shut-off) valve; select the setting range (60-100 kPa here) to bracket the required branch differential pressure, and confirm the connection type (Flange) matches the pipework. Impulse tube is supplied with the valve.
