Danfoss Thermostatic Water Valve AVTA 25 — NPT 1, Universal Charge 0–30 °C

Danfoss AVTA 25 thermostatically operated water valve, genuine OEM code 003N8132. 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. Universal charge with a regulating range of 0–30 °C. Connection NPT 1 internal thread (ANSI/ASME B1.20.1); 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). Universal charge — the liquid point is inside the sensor, so the sensor may be warmer or colder than the valve body and can be installed in any position. EAN 5702423203482.

Compatibility

Self-acting valve — no power supply required. Select charge type (Universal) and regulating range (0–30 °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.
