Butterfly stop valve
If you have any concerns regarding the maintenance, regeneration, or new design of butterfly stop valves (manufactured by Nippon Casting Co., Ltd.), please feel free to consult us.
In 2003, we received a business transfer from the Valve Division of Japan Casting Co., Ltd. and took over the maintenance operations. Our products are used as the main valves for crude oil piping, berths, and crude oil tanks across the country. This butterfly valve features a special rotating mechanism that allows for tight shut-off with a metal seat. While a standard butterfly valve only rotates the valve body approximately 90 degrees, this stop valve moves the valve body further in the seat direction after the rotation, ensuring a firm seal against the seat. The body and valve materials are made of cast steel (WCB, SCPH2, etc.), and the seat area features metal-to-metal contact (Stellite, 17-4PH, etc.). Many of the products already installed have been in use for over 30 years. Due to the high quality of the materials and machining precision originally used, performing an overhaul to regenerate the seat area and replacing parts can restore functionality and further extend the lifespan. We also offer new designs tailored to specifications. We can design the drive mechanism, whether electric or manual (including gear types), according to customer specifications. Please feel free to contact us.
