Background

The new self-balancing expansion valve is driven by the refrigerant input pressure, opening the sliding valve core in an adaptive manner, representing a brand new throttling method for refrigerant output throttling expansion in variable frequency system pipelines.

High precision, fine management, fully applicable to cooling and heating with flow adjustment from low to high across the entire range, achieving low-temperature defrosting, low frequency, intermediate, rated, cooling and heating functions.
