Danfoss WVO 10 Water Regulating Valve G 3/8 in 8 – 12

Danfoss WVO 10 pressure-operated water valve, OEM P/N 003N5203. 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, G (ISO 228-1) water connection. Water connection G 3/8 in (ISO 228-1); refrigerant sensing connection 1/4 in / 6 mm SAE flare. Control pressure range 8 – 12 bar (116 – 174 psig); Kv 1.4 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 adjustment spring to the required condensing pressure. Direct-acting (opens on rising pressure). Confirm code, water connection and setting range before ordering.
