Sanhua DPF-58002 Electronic Expansion Valve Coil

Sanhua DPF-58002 Electronic Expansion Valve Coil is the drive coil that powers the stepper motor of Sanhua DPF series electronic expansion valves and is a critical control part that ensures precise metering of the refrigerant in the refrigeration cycle. It is the preferred choice for replacing worn, burnt-out or unresponsive coils (coils that receive no signal) with a directly compatible new one.

Precise and Stable Control in the Electronic Expansion Valve

The coil converts the pulse (step) signals from the control board into incremental movement of the valve stem, adjusting the expansion opening step by step. This keeps the superheat value stable in air conditioners, heat pumps, cold rooms and supermarket-type refrigeration systems, preserving energy efficiency and cooling performance. Thanks to its push-on design that fits onto the DPF series valve body, removal and installation are practical.
