Overview

VPF250H43 is a high-precision large-flow bidirectional stepping electronic expansion valve developed for heavy-duty commercial HVAC, high-power reversible heat pumps and large industrial refrigeration installations. As the core automatic throttling component of large HVAC systems, it adopts two-phase four-wire permanent magnet stepping motor with 3800 full opening steps, delivering stable bidirectional refrigerant flow regulation. It continuously adjusts refrigerant flow accurately in real time to stabilize evaporator superheat, optimize unit operation conditions and reduce overall power consumption. It supports mainstream refrigerants including R410A, R134a, R407C, R404A, R507A and low-GWP HFO refrigerants, adopts 1-5/8″ ×1-5/8″ ODF straight solder port, supports horizontal and vertical pipeline installation, and features robust structure for continuous heavy-load operation.

Key Features
