Danfoss ASV-PV 3G DN 65 — 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 48 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 003Z0643. EAN 5702421558508. Also supplied under order code 003Z0647 (EAN 5710104524009), an identical DN 65 / 60-100 kPa / flanged ASV-PV 3G valve differing only in packing/order revision.

Danfoss ASV-PV 3G differential-pressure controller for DN 65 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.
