LanguageOur Business
We provide satisfying products with our extensive
experience and reliable technological capabilities for more than half a century.
Who we are
Since its foundation in 1955, we have established our NDV brand as the leading manufacturer of diaphragm valves, contributing to the development of the industrial world and the maintenance of a comfortable social environment.
At present, in addition to our mainstay diaphragm valves, we provide high-performance, safe, and environmentally friendly products that meet diverse needs, such as ball valves and butterfly valves used in a wide range of industries, including chemicals, environmental and water treatment, pharmaceuticals, food processing, semiconductors, steel industries, and power plants.
We will continue to refine our efforts to develop new technologies so that we can deliver products that meet the needs of society while responding to the changing times.
Support for a wide range of users through domestic and overseas group
Domestically, manufacturing, research and development are conducted at the Head Office Plant in Shinagawa, Tokyo. In addition, we have sales offices in five locations nationwide, including the head office, and have established a system that can support a wide range of customers.
Overseas, in 2006 we established a subsidiary in China, TIANJIN DAIYA VALVE CO., LTD. In 2015, we established a NDV(Thailand)Co., Ltd. in Thailand. Furthermore, we are deepening our collaboration with local companies in Vietnam, India, South Korea, and other countries, and are expanding our overseas operations to ensure a sustainable, stable supply of our products and expand sales.
Commitment to society through valve manufacturing
In 1999, we acquired ISO9001 certification, and we are implementing thorough quality-control to ensure that our customers can use our products with trust and confidence. In addition, in 2008 we acquired ISO14001 certification and are continuing to manufacture eco-friendly products.
As our other initiatives, we are continuing our efforts toward society, such as promoting diversity and cooperating with local elementary schools by inviting the students to factory tour as a part of social studies. We will continue to work to contribute to industry and society through the manufacture of valves. Please click on here for our efforts.
