ETO GRUPPE TECHNOLOGIES GmbH

Shut-off valve
Media separation
Customized interface
Suitable for fuel cell applications

The H2 Purge & Drain Valve (P&D) is a specialized valve designed for use in fuel cell applications. It offers shut-off functionality, media separation, and a customizable interface. With a nominal diameter up to 3.5 mm, it operates within a voltage range of 9 to 16 V or 18 to 32 V, and has a nominal current of 2 A. The valve is capable of handling inlet pressures up to 4 barA and has a response time of approximately 20 ms. It ensures minimal H2 leakage at 5E-4 mbar l/s and is rated for a temperature range of -40 to 110 °C. The valve is actuated via PWM (Peak & Hold) and meets IP6K9K protection standards. Ideal for precise and efficient gas management in fuel cell systems.
