Danfoss WVFX 25 Water Regulating Valve G 1 in 4 – 23 003N4105
Danfoss · HVAC & Refrigeration · Water Regulating Valves
Danfoss WVFX 25 pressure-operated water regulating valve, OEM P/N 003N4105. Modulates cooling-water flow to a water-cooled condenser to hold the condensing pressure constant, and shuts the water off when the plant stops. The valve is opened by the condensing (refrigerant) pressure acting on a bellows and is closed by an adjustable spring; the setting is read on a 1–5 scale. Commercial version. Water connection G 1 in (ISO 228-1); refrigerant sensing connection 1/4 in / 6 mm SAE flare. Control pressure range 4 – 23 bar (58 – 334 psig); Kv 5.5 m³/h. Body brass. Max working pressure 16 bar (232 psig). Media: Fresh water, neutral brine. Verify the setting range and refrigerant against the datasheet before ordering.

Compatibility
Fit in the cooling-water line to the condenser with the flow arrow in the direction of flow; the refrigerant sensing flare connects to the condenser/receiver. Set the closing pressure on the 1–5 scale to the required condensing pressure. Direct-acting (opens on rising pressure). Confirm code, water connection and setting range before ordering.
