Product Description

Danfoss WVFX 15 pressure-operated water regulating valve, OEM P/N 003N6004. Modulates condenser cooling-water flow to hold the condensing pressure constant and shuts the water off when the plant stops: the valve is opened by the condensing (refrigerant) pressure on a bellows and closed by an adjustable spring. Opens on rising cond. pressure. Control pressure range 3.5 bar – 16 bar. Water connection 1/2 in G (ISO 228-1); refrigerant sensing 1/4 in - 6 mm SAE flare. Kv 1.9 m³/h. Body Brass. Max working pressure 16 bar (232 psig). Media Fresh water Neutral brine. OEM designation "". OEM P/N 003N6004. EAN 5702423203376. Technical data quoted verbatim from store.danfoss.com (code 003N6004).

Compatibility & Fitment

Fit in the cooling-water line to the condenser with the flow arrow in the direction of flow; the refrigerant sensing connection goes to the condenser/receiver. Set the closing pressure to the required condensing pressure. Direct-acting (opens on rising pressure). Confirm code, water connection and control-pressure range against the datasheet before ordering.
