Map the makers of refrigeration and HVAC control valves and a striking geographic pattern appears: the handful that matter — Sanhua (China), Danfoss (Denmark), and the Japanese trio of Saginomiya and Fujikoki — sit in just three countries. Fujikoki, particularly strong in automotive air-conditioning valves, is one of the Japanese pillars. So the precision valves that meter refrigerant in everything from home air conditioners to car AC to the cold chain are not just supplied by a few firms but cluster in China, Denmark and Japan. That concentration means the cooling and heat-pump value chain is exposed to the trade and industrial policy of a very small number of jurisdictions, not a globally diversified base.

Fujikoki's deep position in automotive air-conditioning valves is becoming an EV story. As vehicles electrify, the cabin air conditioner is joined by a far more demanding job — keeping the high-voltage battery within a narrow temperature band — and the refrigerant-and-coolant control valves that companies like Fujikoki perfected for car AC are exactly the components that EV thermal-management systems need. So a maker of automotive air-conditioning valves is carried, by the same competency, into the heart of EV engineering, where thermal management is a safety- and range-critical system. The unglamorous AC valve becomes a building block of the electric-vehicle supply chain.
