Have you ever been troubled by a sudden halt in valve production? For example… === Production of valves has suddenly stopped, both domestically and internationally… === The successor model lacks compatibility in specifications and dimensions, what should we do… At Keihin Co., Ltd., we manufacture valves that meet our customers' needs, regardless of temperature, material, pressure, size, or shape. Our "Special Valve Production Case Studies" includes numerous examples of special valves we have handled in the past. [Example of a production case] ■ Ultra-high pressure pneumatic operated piston valve → Special materials are used for the valve seat and needle section to enhance durability. ■ Spring return type electric ball valve for air conditioning (steam specification) → Maintenance can be performed while still connected to the piping. ■ Sack-back type pneumatic operated valve unit → Achieved larger sack-back systems, unitization, and improved maintainability. The downloadable materials only include a selection of products. For more details, please contact us.
