The "REF5 Series" is a multi-layer fluorine tube that meets various needs. By using FEP for the interior, it achieves the same level of interior cleanliness (liquid repellency) as single-layer fluorine tubes. Due to its high moisture barrier properties, it can also be used for fluids that react with moisture (such as paint hardeners). The outer layer of nylon elastomer has high gas barrier properties, reducing air ingress (bubble formation) into the fluid, and is resistant to bending, wear, and scratches, making it suitable for piping in robots and other applications. 【Features】 - Significantly improved interior cleanliness - Good gas barrier properties and mobility - Achieves performance equivalent to fluorine tubes while keeping costs down through unique technology - Usable for various applications without compromising flexibility *For more details, please refer to the PDF materials or feel free to contact us.

The "EFV2 Series" is a high-pressure, high-flow overcurrent prevention valve designed for hydrogen stations. It is an overcurrent prevention valve with a flow diameter of φ10, suitable for piping with an internal diameter exceeding φ5 and for medium-pressure piping. The main material used is JIS G4303 SUS316 with a nickel equivalent of 28.5 or higher. Additionally, the external seal employs a metal seal method using a copper gasket, providing excellent gas tightness. The gas contact parts are designed with wall thickness secured by strength calculations in compliance with the High-Pressure Gas Safety Act. 【Features】 ■ The valve automatically operates to stop the flow when the flow rate on the outlet side of the overcurrent prevention valve becomes excessive. ■ The structure allows a slight flow of compressed hydrogen from the valve even during operation. ■ The valve resets due to the spring force when the pressure on the inlet and outlet sides becomes uniform. ■ The external seal uses a metal seal method with a copper gasket. *For more details, please refer to the PDF materials or feel free to contact us.

The "EFV1 Series" is an overflow prevention valve for hydrogen stations. When the flow rate on the outlet side of the overflow prevention valve becomes excessive, the valve automatically activates to stop the flow. The main material used is JIS G4303 SUS316 with a nickel equivalent of 28.5 or higher. Even during operation, a small amount of compressed hydrogen flows from the valve section, and when the pressure on the inlet and outlet sides becomes uniform, it is automatically reset by the force of a spring. 【Features】 ■ A structure that allows a small amount of compressed hydrogen to flow from the valve section during operation ■ Automatically resets when the pressure on the inlet and outlet sides becomes uniform due to the force of a spring ■ External sealing uses a metal seal method with copper packing ■ The gas contact parts are designed with thickness secured by strength calculations in compliance with the High-Pressure Gas Safety Act *For more details, please refer to the PDF document or feel free to contact us.

The "HPB Series" is a mechanical pressure relief valve (back pressure valve) developed to withstand a maximum operating pressure of 100 MPa. The main material used is JIS G4303 SUS316 with a nickel equivalent of 28.5 or higher. It is a self-supporting mechanical design that does not require a power source, contributing to miniaturization and space-saving. The gas contact parts are designed with wall thickness secured through strength calculations in compliance with the High-Pressure Gas Safety Act. If an orifice is not installed to release the specified flow rate, it can be used as a back pressure valve for ultra-high pressure. 【Features】 ■ Newly designed valve structure and piston mechanism ■ Achieves stable starting and stopping pressures ■ Can be used as a back pressure valve for ultra-high pressure if no orifice is installed ■ Gas contact parts are designed with wall thickness secured through strength calculations in compliance with the High-Pressure Gas Safety Act *For more details, please refer to the PDF document or feel free to contact us.

The "HPRL Series" is a pressure regulator designed to fill compressed hydrogen into the storage units of off-site hydrogen stations. In addition to filling hydrogen stations, it is also suitable for applications that involve recovering used gas and repressurizing it. The main material used is JIS G4303 SUS316 with a nickel equivalent of 28.5 or higher. Furthermore, compressed hydrogen transported by trailers can be depressurized using this product and then repressurized with a compressor, allowing for efficient filling of compressed hydrogen into storage tanks. 【Features】 ■ Adopts a newly designed piston-type pressure reduction mechanism ■ Provides stable pressure regulation while accommodating ultra-high pressure ■ Simple single-stage pressure reduction method ■ Minimizes changes in outlet pressure due to fluctuations in inlet pressure *For more details, please refer to the PDF document or feel free to contact us.
