Danfoss Thermostatic Water Valve AVTA 20 — NPT 3/4-14, Adsorption Charge 10–80 °C — 003N7120
Danfoss · HVAC & Refrigeration · Water Regulating Valves
Danfoss AVTA 20 thermostatically operated water valve, genuine OEM code 003N7120. 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. Adsorption charge with a regulating range of 10–80 °C. Connection NPT 3/4-14 (ANSI/ASME B1.20.1); 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 150 mm, capillary 2300 mm). Adsorption charge — sensor can be installed in any position; regulating point independent of sensor orientation. EAN 5702423052349.

Compatibility
Self-acting valve — no power supply required. Select charge type (Adsorption) and regulating range (10–80 °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.
