01 Who we are

A factory, not a trading desk.

When you buy from Kailing you buy from the people who machine the valve body, wind the coil into the armature tube, fit the seals and put the finished valve on the test bench. That is why we can hold specifications, adjust designs for OEM programs and answer technical questions the same day.
