- product introduction:The self-balancing expansion valve automatically adjusts the flow rate based on the side pressure difference of high and low pressure under different working conditions to achieve the optimization of cooling and heating. Driven by the input pressure of the refrigerant, the sliding spool is opened, and a new throttling mode of the refrigerant output expansion is managed through the multi-stage variable diameter shape adaptive frequency conversion system of the spool. Its high precision, good stability and low cost can fully meet the international standard GB21455-2019.
