Product Description
Danfoss WVFX 25 pressure-operated water regulating valve, OEM P/N 003N4410. 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. High-pressure refrigerant version (refrigerant-side MWP 45.2 bar). Water connection G 1 in (ISO 228-1); refrigerant sensing connection 1/4 in / 6 mm SAE flare. Control pressure range 15 – 29 bar (232 – 421 psig); Kv 5.5 m³/h. Body brass. Max working pressure 16 bar (232 psig) water side; 45.2 bar (655 psig) refrigerant side. Media: Fresh water, neutral brine. Verify the setting range and refrigerant against the datasheet before ordering.
