Product Description
Danfoss ASV-PV 3G DN 250 — 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 70-150 kPa (factory setting ), Kvs 400 m³/h, Grey cast iron EN-GJL-250 (GG-25) body, Flange connection, PN 16, media temperature 2 °C to 120 °C, integral shut-off. OEM P/N 003Z0686. EAN 5710104509723. Technical data quoted verbatim from store.danfoss.com (code 003Z0686).

Compatibility & Fitment
Danfoss ASV-PV 3G differential-pressure controller for DN 250 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 (70-150 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.
