Collaboration with KITZ Corporation

In February 2016, we concluded a business alliance agreement with KITZ Corporation through which both companies realize synergies by working together to make good use of their principal technologies and fields of product specialization. The two companies are now benefitting from these synergies across a wide range of areas including procurement, technology, production, sales, service, and especially the field of high-pressure valves. Collaborations between the two companies have already resulted in record domestic and international sales to electric power plants and oil refineries. The two companies remain committed to a cooperating further in a many fields of endeavor in an effort to increase orders.

  • Operations outside Japan

    We intend to strengthen our sales of high-pressure valves by linking KITZ Corporation’s extensive international network (encompassing sales, production, and procurement) with our own extensive network of customers in East Asia and Southeast Asia. The valves sold in these markets will be serviced by our Singapore subsidiary, and we aim to expand the valve business of both companies by offering Valve Life Cycle Management, which comprises everything from development and implementation to maintenance and management.

  • Domestic Business

    Building on KITZ Corporation’s record of sales to a wide range of industrial plants, we have begun to use our combined network to market our products to the electric power industry and other sectors dealing with high-temperature and high-voltage environments. In addition, by linking the service networks of both our companies, we are able to provide our customers with prompt service.

Benefits of alliance

Our collaboration with KITZ Corporation continues to bear fruit.
In terms of sales, we were among the first to win several joint orders. These included biomass power generation plants in Japan and petrochemical plants and coal gasification combined-cycle power generation demonstration test plants outside Japan.
Moreover, we are strengthening our collaboration in terms of both technology and production and are preparing to launch new products.
Looking to the field of maintenance, we are collaborating with KITZ Engineering Service Co., Ltd., to take advantage of our mutual strengths as we begin to offer innovative services that are growing at an unprecedented rate.
