Danfoss Thermostatic Water Valve AVTA 20 — G 3/4 (ISO 228-1), Mass Charge 25–65 °C — 003N0046
Danfoss · HVAC & Refrigeration · Water Regulating Valves
Danfoss AVTA 20 thermostatically operated water valve, genuine OEM code 003N0046. Self-acting proportional temperature-regulating valve for cooling-water and heating circuits: it opens on rising sensor temperature and needs no external power supply, compressed air or electricity. Mass charge with a regulating range of 25–65 °C. Connection G 3/4 internal thread (ISO 228-1); kv 3.4 m³/h; brass valve body. Pressure-relieved design — the degree of opening is not affected by differential pressure. Supplied complete with capillary tube gland and hermetically sealed thermostatic element (sensor 9.5 x 180 mm, capillary 2000 mm). Mass charge — the sensor must always be warmer than the valve body; mount the sensor above the valve. Supplied for G (ISO 228-1) connections. EAN 5702423024025.

Compatibility
Self-acting valve — no power supply required. Select charge type (Mass) and regulating range (25–65 °C) to suit the temperature to be maintained; aim to keep the required sensor temperature near the middle of the range. Install an FV strainer ahead of the valve; route the capillary without kinks.
