This device properly adjusts the decompression of hydrogen stored in high-pressure tanks at up to 87.5 MPa.

The Keihin Advantage

Compact and lightweight
The device uses Keihin’s first-ever piston pressure-receiving structure for a smaller, lighter design.A forged aluminum body is part of the weight-conscious design as well.

Superior sealing characteristics at all temperature ranges
The resin valve seat is durable and delivers exceptional airtightness at extremely low temperatures for outstanding sealing performance throughout a wide temperature range.The valve structure also incorporates decompression technologies from natural gas vehicles for high-precision decompression.

Customer Benefits

・The device maintains a stable hydrogen supply while reducing the size and weight of high-pressure hydrogen systems, which in turn allows for lighter, more compact vehicles.
