Compatibility

Rotary 3-way mixing valve for weather-compensated heating and cooling circuits. Turn the threaded body with a Danfoss AMB rotary actuator (ordered separately) or the manual handle. Confirm valve size (DN 25), Kvs (10 m³/h m³/h), PN 10 and thread size Rp 1 against the HRB/HRE/HFE data sheet before ordering; the actuator, connection set and stuffing-box service parts are ordered separately (065Z0439-0461).
