Danfoss Thermostatic Water Valve AVTA 25 — G 1, Mass Charge 25–65 °C — 003N0047
Danfoss · HVAC & Refrigeration · Water Regulating Valves
Danfoss AVTA 25 thermostatically operated water valve, genuine OEM code 003N0047. 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 1 (ISO 228-1); kv 5.5 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 18 x 210 mm, capillary 2000 mm). Mass charge — the sensor must be installed in an environment warmer than the valve body; short time constant. EAN 5702423005574.

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.
