Danfoss FJVA 20 thermostatically operated cooling-water valve, OEM P/N 003N8244. Self-acting valve that regulates the flow of condenser cooling water from the water temperature — the entire filled bellows element acts as the temperature sensor, so no separate capillary bulb is required. Opens on rising sensor temperature; fit in the cooling-water return line. Brass body, G (ISO 228-1) 3/4 in internal connection. Kv 3.4 m³/h; orifice 20 mm; bypass 2 mm. Low-range sensor temperature setting 0 – 30 °C. Max working pressure 16 bar; differential pressure 0 – 10 bar; media temperature –25 to 130 °C. Neutral media. Confirm the setting range and code against the datasheet before ordering.
