Description Vendor

The H2 Flow Control Valve - High Pressure is a high-pressure proportional valve designed for precise hydrogen flow control. It features a linear flow characteristic, an integrated shut-off valve, and customizable interfaces with various connectors such as Deutsch and DIN. Suitable for applications like fuel cells, electrolyzers, and H2 ICE, as well as DI and PFI systems. Offers high reliability with a response time of approximately 25 ms and minimal hydrogen leakage of 5E-4 mbar l/s. The valve operates using PWM (current control) and is rated for a nominal diameter of 2.9 mm, with a voltage range of 22 to 32 V and a control current range of 0.6 to 1.2 A. It can handle inlet pressures up to 45 bar and has a burst pressure rating of 110 bar, operating within a temperature range of -40 to 125 °C. Its high precision and durability make it an ideal choice for demanding hydrogen-related applications.

Use Cases

  • Fuel cell
  • Electrolyzer
  • H₂ Internal Combustion Engines (H2 ICE)

Capabilities

  • Controls hydrogen flow proportionally and precisely.
  • Delivers a linear flow characteristic for accurate regulation.
  • Handles high inlet pressures up to 45 bar.
  • Integrates a reliable shut-off function.
  • Supports customized interfaces and multiple connectors.
  • Operates reliably in harsh environments (IP6K9K, −40 °C to +125 °C).
ETO GRUPPE TECHNOLOGIES GmbH ETO GRUPPE, a German actuator and sensor manufacturer with more than 75 years of experience, specializes in high-quality electromagnetic components setting standards for modern vehicles and industrial systems, including a dedicated portfolio of solenoid valves and sensors engineered specifically for hydrogen applications. ETO's hydrogen solenoid valves and pressure sensors are designed to be highly leak-proof and resistant to high pressures and low temperatures, meeting the highest safety, material resistance, and reliability requirements across industry, passenger cars, and commercial vehicle hydrogen applications. In passenger cars, ETO solenoid valves control hydrogen refueling and withdrawal while pressure sensors monitor tank pressure; in industry, ETO solenoid valves control hydrogen flow within production systems; and in commercial vehicles, the company's pneumatic and hydraulic solenoid valve technology (developed over 75+ years for medium- and heavy-duty trucks) extends to hydrogen valve and sensor applications alongside existing product lines for air suspension, braking, clutch, and engine systems. With reported revenue exceeding $444 million and recognized global leadership in solenoid valves for commercial vehicles and two-pin actuators for passenger car camshafts, ETO GRUPPE continues expanding its hydrogen technology portfolio as part of its focus on electromagnetics and automation for future mobility.
