Product Description
Danfoss FJV self-acting temperature limiter, OEM P/N 003N8218. Direct-acting proportional temperature controller used to limit the temperature of circulation water in district heating and cooling circuits; the bellows element senses the medium temperature and throttles the valve. DN 20, PN 16, internal thread Rp 3/4 in (ISO 7/1). Kvs 3.4 m³/h; temperature setting range 50 – 90 °C, linear characteristic. Brass body (CuZn40Pb2, W.-Nr. 2.0402), NBR valve cone, Cr Ni steel valve seat (W.-Nr. 1.4301). Max differential pressure 10 bar; media temperature 2 – 130 °C. Approved to ETA VA 1.54/18952. Confirm the setting range and code against the datasheet before ordering.
