ETS 6 is a compact and lightweight electric expansion valve. The current range is available with different capacities, and can be used with all common refrigerants (R410A, R407C, R404A, R134a, R22). Bi-flow operation is also possible for heat pump systems. The valve design uses uni-polar drives, and different control solutions exist that are compatible with uni-polar drives. The valve operation is by means of a uni-polar motor, which can be controlled by a number of controllers from Danfoss or third party vendors. With a Danfoss EKD 316 and EIM 336 (current driver) and an AKS sensor, an accuracy better than +/-0.5 K can be obtained. Optimized energy efficiency of the system. Precision flow control with high resolution. Compact and lightweight. Energy saving design. Proven know-how and high reliability. Wide range for all common refrigerants (R410A, R407C, R404A, R134a, R22). For other refrigerants, please contact Danfoss. Bi-flow for heat pump applications.
