Part Number
034G3607 · HS 8481.80

Danfoss ETS 250L Colibri electric (stepper-motor) expansion valve, code 034G3607. Brass-body in-line valve with 1 3/8 in (35 mm), Solder ODF inlet and outlet, balanced port, bi-flow, and integrated sight glass with moisture indicator. Kv 13.9 m³/h, Cv 16.1 gal/min. A 2-phase bi-polar permanent-magnet stepper gives modulating liquid-refrigerant injection for large HVAC-R evaporators and heat pumps. MWP 37 bar (536 psig); MOPD 26 bar (377 psi) forward / 17 bar reverse. Refrigerant -40 to 70 °C (up to 95 °C oil-free / high-temperature version); ambient -40 to 70 °C; IP67 M12 4-pin. Driven by a Danfoss EKE, EKF, MCX or AK-XM 208C driver (ordered separately). OEM P/N 034G3607, EAN 5715162282991.

Compatibility

ETS Colibri is a driver-controlled stepper valve — it does not operate stand-alone. Drive with a Danfoss EKE, EKF, MCX or AK-XM 208C driver providing the stepper phase current. M12 4-pin connection cable (034G70xx/71xx) ordered separately. Verify model capacity class, inlet/outlet ODF size and refrigerant before ordering.
