Danfoss HFE 3 rotary 3-Way mixing valve body DN 65 Kvs 90 m³/h PN 6 flanged (065Z0433)

Danfoss HFE 3 3-way rotary mixing valve body (OEM designation "HFE 3 PN6 65/90 rotary 3-way Flange"). A rotating-slide 3-way valve for mixing or diverting service in heating and district-heating circuits — the slide is turned through 90° by a Danfoss AMB rotary actuator (ordered separately) or by the manual handle. Valve size DN 65; PN 6; Kvs 90 m³/h m³/h; Flange connection (PN 6); S characteristic flow characteristic; operating torque 10 N-m. Body Grey cast iron EN-GJL-250 (GG-25); cone DZR brass CuZn36Pb2AS (CW 602N); slide shoe DZR brass CuZn36Pb2AS (CW 602N); stuffing-box seal EPDM; port leakage Diverting: 0.5 | Mixing: 1.0 % Kvs. Maximum closing differential pressure 0.5 bar (mixing) / 0.5 bar (diverting). Media District heating/cooling circulation water — alternative Glycolic water up to 50%, 2 °C to 110 °C. OEM P/N 065Z0433. EAN 5710104033501.

Compatibility

Rotary 3-way mixing valve for weather-compensated heating and cooling circuits. Turn the flanged body with a Danfoss AMB rotary actuator (ordered separately) or the manual handle. Confirm valve size (DN 65), Kvs (90 m³/h m³/h), PN 6 and flange drilling against the HRB/HRE/HFE data sheet before ordering; the actuator, connection set and stuffing-box service parts are ordered separately (065Z0439-0461).
