Did you know2024
The refrigeration-valve company turns out to be one of the most important suppliers inside electric vehicles. Sanhua applied its core competency — precise control of fluid and refrigerant flow — to EV thermal management, making the integrated valve-and-pump modules that cool battery packs and cabins and run EV heat pumps, and becoming a major supplier to Tesla and other automakers. So the same Chinese company that makes the valve in your air conditioner also makes the thermal plumbing that keeps an EV battery in its safe temperature window. As thermal management becomes one of the defining engineering problems of electric vehicles, a maker of air-conditioner valves has quietly become a critical EV-supply-chain node — cooling, repurposed from buildings to cars.

Zhejiang Sanhua is the Chinese half of the electronic-expansion-valve duopoly it shares with Denmark's Danfoss — and the world's largest maker of HVAC and refrigeration valves overall (EEVs, four-way reversing valves, solenoid valves, microchannel heat exchangers). Between Sanhua and Danfoss, a majority of the precision valves that make modern variable-speed air conditioning, heat pumps and refrigeration work pass through two companies on opposite sides of the world. For anyone modeling the supply risk of the cooling/heat-pump transition or the food-and-pharma cold chain, this is the core fact: the enabling valve is a two-supplier, two-country dependency, and Sanhua is the larger-volume, China-based pole of it.
