Product Description
Danfoss ASV-P — self-acting differential-pressure controller (fixed setting), OEM order code 003L7623. Self-acting (automatic) differential-pressure controller for automatic hydronic balancing, factory-set to a fixed differential pressure (10 kPa) and non-adjustable. Fitted in the return of a riser and linked by an impulse tube to an ASV-I or ASV-M partner valve on the supply, it keeps the differential pressure across the riser constant as loads elsewhere in the system change. A constant riser differential pressure preserves two-way control-valve authority and suppresses flow noise at part load. (ASV-P DN 25, internal thread, automatic balancing valve.) Nominal size DN 25, Kvs 4 m³/h, PN 16, Internal thread connection, Brass body, media temperature -20 °C to 120 °C. Fixed differential-pressure setting 10 KPa, max. differential pressure over the valve 150 KPa. Net weight 1.888 Kilogram. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 003L7623). OEM P/N 003L7623, EAN 5702421527832. Used in commercial refrigeration, provision-room cooling and reefer plant rooms across HFC, HFO and CO2 (R744) refrigerants.

Compatibility & Fitment
Self-acting differential-pressure controller for the return of a DN 25 riser, fixed setting 10 KPa. Pair with a Danfoss ASV-I or ASV-M partner valve on the supply and connect the impulse tube. Confirm connection type (Internal thread) and nominal size (DN 25) match the pipework; use the adjustable ASV-PV controller instead where a variable setpoint is required.
