Usage: danfoss ETS series electronic expansion valve used in air conditioning and refrigeration, precise control of liquid refrigerant injection evaporator. Valve piston and linear positioning design can achieve balance in full, so that the fluid in the forward and reverse characteristics of the two flow direction. In addition, it has double check function, like electromagnetic valve closed tightly. Bipolar drive valve design provides accurate flow control. Can use other manufacturers of DANFOSS and electric control scheme. ETS design has applied for patent.
Features: accurate location to ensure that the refrigerant injection quantity optimal control; Applicable to various common refrigerant (R410A and R407C, R404A, everything, R22); ETS12.5 ETS25, ETS50 and ETS100 maximum working pressure of 45.5 bar (660 psig). ETS250 and ETS400 maximum working pressure is 34 bar (493 psig); ETS50 to ETS400 electronic expansion valve design to realize the dynamic balance of not only enables the valve to the bidirectional flow operation, also has the double check function, like electromagnetic valve closed tightly; ETS50 and ETS100 anhydrous welding joint, make welding without wet cloth package, convenient and quick. ETS50 to ETS400 electronic expansion valve are depending on the liquid mirror has a built-in. Internal and external anti-corrosion design. Low power consumption. Can choose according to the requirement cables and connectors. EKC316A, EKC312 and danfoss EKD316 are commonly used for driving the ETS electronic expansion valve controller. Provide AST - g hand of electronic expansion valve is used to ETS manual operation and maintenance.
