Danfoss ETS 6 electric expansion valve (ETS 6-08 to 6-40)

The Danfoss ETS 6 is a small stepper motor electric expansion valve for display cases, cold rooms, air conditioning and small heat pumps. Compact and lightweight, it controls injection precisely from 10 to 100% of its capacity and works in both flow directions, which suits reversible heat pumps. Eight sizes, from ETS 6-08 to ETS 6-40, cover 1.1 to 27.6 kW with R404A.

ETS 6 sizes

Danfoss rated capacities: evaporating +5 °C, condensing 38 °C, no subcooling or superheat. Copper solder connections, angle way (90°). The box of 100 reference is intended for OEMs.

Key benefits

• Precise control: 480 half-step stroke, stable control from 10 to 100% of capacity.
• Bi-flow: works in both directions, for reversible heat pumps.
• Proven reliability: tested by Danfoss for 60 million pulses and 30,000 full strokes.
• Many refrigerants: R22, R32, R134a, R290, R404A, R407C, R407H, R410A, R448A, R449A, R452A, R452B, R454C, R463A, R513A and R1234yf (flammable refrigerants according to EN 378).
