York Expansion Valve 034G0507

The 034G0507 component provided by York is a Danfoss ETS100 series original factory electronic expansion valve. It is a standard throttling control component for the refrigeration circuits of small and medium-sized York chillers and can also be adapted for the refrigerant regulation of the economizer branch of the unit.

This valve adopts a 1-1/8 inch ODF welded interface and is originally compatible with mainstream refrigerants such as R134a, R22, and R404A. Under standard conditions, the cooling capacity reaches 100 ton-level, and the maximum refrigerant tolerance temperature is 65℃. It is suitable for the regular operation conditions of the refrigeration room.

Based on the stepper motor drive, it realizes continuous regulation of micron-level opening degree, can precisely control the evaporator superheat, quickly respond to the fluctuations of the terminal load, keep the system in the optimal operating state all the time, and effectively improve the overall energy efficiency; when the unit is shut down, it can be tightly closed and also has the function of a stop valve, avoiding the reverse flow of high-pressure refrigerant impacting the compressor. The product is the original factory compatible specification of York, can be directly replaced in situ, and is the core spare part for unit maintenance and throttling system upgrade.
