High-performance valve
The essence of valves is not to leak. And the most important thing to manufacture valves with no leak depends on the sphericity of the disk which banks up the liquid, called valve disks. On the other hand, this work which requires extremely delicate technology and know-how is one of the fields which are difficult to automate in the increasingly innovative valve manufacturing processes. Thus, Hatanaka Special Valve Industry consciously attaches importance to the good-old manual polishing work by craftsman. In this age of increasingly automated manufacturing, this work may seem very feudalistic. However, the know-how and experience of craftsman which shine brighter in such analogue environment which is not affected by the automation is the biggest strength and pride of Hatanaka Special Industry.
