Company information
Manufacturing, repairing, and creating valves Nakamura Valve Manufacturing Co., Ltd. has been consistently engaged in valve manufacturing since its establishment in 1947 (Showa 22), walking alongside the development of Japan's petrochemical industry. We are approaching our 80th anniversary. We sincerely thank you for your warm support. Through the technology accumulated over many years of valve manufacturing, we contribute to the maintenance and development of the industrial infrastructure as a behind-the-scenes supporter. About 80% of our sales come from our own products, while the rest consists of assisting other companies in the same industry and valve maintenance. While many manufacturers are switching to overseas materials, we have continued to prioritize domestic materials for our products since our founding, particularly selecting high-quality cast steel materials for pressure-resistant components to ensure stable quality. Even if you require special materials that are difficult to obtain domestically, we can procure the requested materials in consultation with our customers. We manufacture and sell on a made-to-order basis, but we also have a small stock of materials for products that receive frequent inquiries. Please contact us if you need something urgently. If you have any concerns regarding valves, please feel free to consult with us.
