If you have any issues with valve design, manufacturing, or parts processing, please consult our company!
Our company utilizes the valve manufacturing technology we have cultivated over many years to support our customers in solving their "troubles" by assisting with a series of processes necessary for valve manufacturing, such as design, procurement, processing, welding, assembly, and various inspections like leakage and pressure resistance, as well as partial processes like machining. Currently, in addition to our own product areas, we are helping with the production of various types of valves for different industries, including fire protection equipment valves, bellows seal valves, wafer check valves, emergency shut-off valves, rubber insert butterfly valves for powder, and marine valves. We particularly excel in large-diameter valves (up to 60 inches), with individual parts capable of being processed up to 5 tons. 【Types of valves we can manufacture with our own products】 ■ Shut-off valves, ball valves, swing check valves, tilting check valves (Pressure seal types are also available) (Check valves can be equipped with counterweights, cylinders, etc.) (Jacket types are also available) ■ Cock valves, plug valves (Grease seals are the main type) ■ Butterfly stop valves 【Types of valves we can manufacture with supplied materials】 ■ In addition to general valves, we can also produce ball valves, strainers, diaphragm valves, pinch valves, through conduit valves, and more. *Please feel free to contact us.

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.
