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 0–30 °C. Connection G 3/4 internal thread (ISO 228-1); kv 3.4 m³/h; brass valve body.
