Danfoss RTX (limiter) return-temperature limiter — wax-charged, self-acting, for Danfoss RTX design-radiator valves (013G6190)

Danfoss RTX (limiter) — self-acting return-temperature limiter for design radiators, OEM order code 013G6190. The RTX (limiter) is a self-acting return-temperature limiter that throttles a design (towel / decorative) radiator when its return-water temperature exceeds the set value, so the radiator draws only the intended share of heat. It is wax-charged and needs no power or wiring; the sensing element is built into the head. Setpoint range 10 °C - 50 °C. Features: positive shut-off (closes the valve at the low end of the scale). Valve connection RTX. Genuine Danfoss part; specification quoted verbatim from store.danfoss.com (code 013G6190). OEM P/N 013G6190, EAN 5702420066035. Used in commercial refrigeration, provision-room cooling and reefer plant rooms across HFC, HFO and CO2 (R744) refrigerants.
