At the end of 2009, Japan Daikin China Branch purchased a sample of 3-way DN25 electric ball valve from our company for Daikin VRV water system. On March 8, 2010, a group of 6 people from Daikin Company visited our company for inspection and guidance. After 3 to 4 months of cooperation and related management improvement, our company officially began to supply to Daikin. It has been 11 years so far.
