Hydrogen high pressure solenoid valve – type 3108 A-9/16 – H35

The Seitz HyValve range of products has been developed for the dispensing of hydrogen for pressure ranges up to 1000 bar and is designed according to highest quality and safety standards.

Their highly compact, modern design saves space and investment for any refueling system application. The broad temperature range allows a safe and fast filling process, no matter where the station may be located.

Supporting pre-cooled hydrogen down to -50°C, our HyValve range boasts high availability due to the broad temperature range, utmost safety and exceptional reliability.

Hydrogen solenoid shut-off valve, piloted with own fluid

Every valve tested at 100% with hydrogen gas mixture

All wetted materials fully hydrogen compatible, no hydrogen embrittlement

High-performance dynamic seals for lowest leakage and long service life

Project cases

Hydrogen refueling stations (HRS), HyValves are used for managing hydrogen gas flow in and between storage banks (cascade), cryo-pump, compressor and dispenser.

The highest-capacity and fastest-flow refueling stations in the world rely on HyValve performance.

HyValves are actively operating in refueling stations in USA, Europe, China and more countries.

HyValves are also used as shut-off valves upstream of hydrogen pressure regulators, to enable the downstream pressure regulator to remain gas-tight.
