Danfoss 034G1708 Electronic Expansion Valve

Description:

Danfoss Electric 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 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 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.
