Product Description
Danfoss WVFX 25 pressure-operated water valve, OEM P/N 003N8025. Regulates the flow of cooling water to a water-cooled condenser from the condensing (refrigerant) pressure and shuts the water off when the plant stops. Opens on rising condensing pressure; narrow control-pressure band set on the adjustment spring. Brass body, NPT (ANSI/ASME B1.20.1) water connection. Water connection NPT 1-11.5 in; refrigerant sensing connection 1/4 in / 6 mm SAE flare, 800 mm capillary. Control pressure range 4 – 23 bar; Kv 5.5 m³/h. Body brass. Max working pressure 16 bar (232 psig). Media: Fresh water, neutral brine. 800 mm capillary tube for remote sensing. Verify the setting range and refrigerant against the datasheet before ordering.
