Danfoss WVO 10 Water Regulating Valve NPT 3/8-18 in 14 – 18

Danfoss WVO 10 pressure-operated water valve, OEM P/N 003N8026. 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 3/8-18 in; refrigerant sensing connection 1/4 in / 6 mm SAE flare, 900 mm capillary. Control pressure range 14 – 18 bar; Kv 1.4 m³/h. Body brass. Max working pressure 16 bar (232 psig). Media: Fresh water, neutral brine. 900 mm capillary tube for remote sensing. 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.
