The NR2-S type check valve is a compact inline design that can be widely used for general fluids to special fluids. It uses a spring and has a highly seat-structured design. We also offer special adaptations such as changes to the valve opening pressure beyond standard specifications. Please feel free to contact us. We also handle high-pressure specifications. (Check valve, check valve)

Titanium is a lightweight metal with excellent corrosion resistance. It is suitable for controlling acidic fluids such as ballast water, seawater, and sodium hypochlorite, and it also possesses high strength. Please feel free to contact us for inquiries regarding connections, diameters, and structures. *The photo is a reference product (check valve, non-return valve).

It is a lightweight and compact wafer-type check valve. Maintenance is also easy. It is possible to select products that accommodate various specifications. Check valve, non-return valve. ◆◇ For more details, please contact us or download the catalog. ◇◆

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.

Are you having trouble finding a flange-connected valve, saying "there are only threaded products," or "I found a nipple flange on the internet, but the face-to-face distance is too long, and I can't secure enough piping space..."? Our company sells welded fittings that connect nipples and flanges with R × JIS 10K-FF connections as shown below. Please feel free to contact Keihin when you have any issues. ◆ Features - The face-to-face distance is short, at 39.5mm on one side (79mm for a set). *This dimension is for 25A. - We offer diameter sizes from JIS 10K-FF 15A to 25A. - We have two material options available: SS400 and SUS304.

At Keihin, we handle a variety of special valves that are not available from other manufacturers. Customization is possible to meet various conditions, such as accommodating high pressure, low temperature/high temperature, and changing materials according to the corrosiveness of the fluid. We can control fluids such as water, air, oil, and steam. Specifications that are difficult for other manufacturers can be consistently managed from design to production, responding to requests regarding fluid specifications such as fluid, pressure, and temperature, as well as material, connection, and size. 【Example of Products】*Customization is also available for catalog-listed items ■ Pneumatic Piston Valve 　⇒ Products compatible with 60 to 80 MPa ■ Solenoid Valve 　⇒ Products compatible with 20 MPa 　⇒ Products compatible with 250°C 　⇒ Products compatible with -196°C ■ Electric Valve 　⇒ Electric valve with a resin body material and spring return type (emergency shut-off valve) ■ Check Valve 　⇒ Products made of Hastelloy material ■ Others 　⇒ Various valves compatible with seawater 　⇒ OEM products for specific customers, etc.

Keihin's various valves, which are responsible for fluid control in all fields, are applied in a variety of areas.
