Product Description
Danfoss thermostatic element, genuine OEM spare code 003N0077, for AVTA / AVTB (and FJVA / FJV) self-acting temperature-regulating valves. Hermetically sealed universal-charge unit comprising sensor, capillary and bellows; it converts a rising medium temperature into the force that opens the valve — no external power needed. Regulating range 0–30 °C (AVTA / FJVA). Sensor 18 x 210 mm, capillary 5000 mm, max. sensor temperature 57 °C. Replaces a worn or wrongly-ranged element without changing the valve body. EAN 5702423006878.
