Product Description
Danfoss AVTA 15 thermostatically operated water valve, genuine OEM code 003N0034. 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 1/2 internal thread (ISO 228-1); kv 1.9 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 5000 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 5702423017072.

Compatibility & Fitment
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.
