Danfoss Electronic Expansion Valve

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

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 and benefits

  • Precise positioning for optimal control of liquid injection.
  • Wide range for all common refrigerants R410A, R407C, R404A, R507, R134a, R448A, R449A, R22, R1234ze and other refrigerants. (special valves for R744 (CO2) are available).
  • ETS 12.5, ETS25, ETS 50 and ETS100 provides working pressure of 45.5 bar / 660 psig and ETS 250, ETS 400 provides 34 bar / 493 psig.
  • Balanced design (ETS 50 – ETS 400) providing bi-flow operation as well as solenoid tight shut-off function in both flow directions.
  • ETS 50 and ETS 100 feature improved process and productivity due to waterless brazing i.e soldering without wet cloth for cooling.
  • ETS 50 – ETS 400 are all designed with built-in sight glass with moisture indicator.
  • Internal and external corrosion resistant design.
  • Low power consumption.
  • Cable and connector assemblies as accessories.
  • EKC 316A, EKC 312 and EKD 316 are examples of Danfoss controllers with drivers matching the ETS needs.
  • For manual operation and service of ETS valves an AST-g service driver is available.
