Overview

VPF12.5H53 is a compact bidirectional electronic expansion valve of the VPF series, professionally developed for small and medium-sized HVAC equipment, residential air conditioners and low-power air source heat pump systems. It adopts 2-phase 4-step permanent magnet stepping motor driving structure, with fine stroke steps to achieve continuous high-precision adjustment of refrigerant flow, which can stabilize the variable-load operation of HVAC equipment in heating and cooling modes. The bidirectional equal flow design ensures consistent control performance under forward and reverse flow, effectively optimizing system energy efficiency, improving temperature control accuracy, and adapting to mainstream refrigerants such as R32, R410A and R134a, greatly improving the stability and energy-saving performance of small HVAC and refrigeration closed-loop systems.
