Electric expansion valve

Type ETS 12.5 - ETS 400

ETS is a series of electric expansion valves for

precise liquid injection in evaporators for air
conditioning and refrigeration applications.

The valve piston and linear positioning design is

fully balanced, providing bi-flow feature as well
as solenoid tight shut-off function in both flow
directions.

The valve design uses bi-polar drive providing

very precise flow regulation.

ETS valves are compatible with electronic control

solutions from Danfoss and other manufacturers.

Features • Precise positioning for optimal control of • ETS 50 – ETS 400 are all designed with built-in

Accessories:
M12 angle cable M12 angle female connector is intended for use with a standard M12 male connector,
available on stepper motor valves.
This cable is designed to offer high flexibility and small outer diameters with tensile strength.
The angle way M12 cable consist of paired, twisted wires, which decreases mutual influence between
signals transmitted along the cable and reduces influence of external sources of interference. The
cables thus provides a higher degree of protection against lost steps compared to other cables.
