The H2 Shut-off Valve (SOV) is a pilot valve with low pressure drop, designed for safe operation through pressure-loaded closing. It is suitable for applications such as fuel cells, electrolyzers, and H2 ICE, with customizable interfaces and various connectors available, including Deutsch and DIN. The valve operates with PWM (Peak & Hold) actuation and has a temperature range of -40 to 125 °C. It offers high performance with an H2 flow of 35 kg/h at a pressure drop of 0.5 bar and minimal H2 leakage of 1E-4 mbar l/s. It is also suitable for DI & PFI applications. The valve is engineered to ensure reliable and efficient hydrogen control, making it a critical component in hydrogen-related systems.
