Here’s a list of commonly used valve types in the hydrogen industry, each serving specific functions to ensure safe and efficient hydrogen handling:
- Ball Valves
Primarily used for controlling the flow and isolation of hydrogen in both gaseous and liquid forms. They provide tight sealing with a rotary ball design, suitable for high pressure and temperature conditions, making them ideal for high-throughput and high-pressure hydrogen systems. - Gate Valves
Employed for on/off control of hydrogen flow in pipelines, particularly suitable for large diameter connections. These valves offer low pressure drop when fully open and provide good sealing capabilities when closed. They are not recommended for throttling as they are prone to wear under such conditions. - Globe Valves
Ideal for regulating flow and pressure within hydrogen systems, used in applications requiring precise control over valve throttling. Their design allows for better throttling control compared to gate or ball valves, featuring a movable disk-type element and a stationary ring seat in a generally spherical body. - Check Valves
Prevent reverse flow in piping systems, ensuring that hydrogen gas flows in one direction, which is crucial for maintaining system integrity and safety. These valves automatically open and close based on the flow and pressure in the pipeline and are available in various designs such as swing check, lift check, and wafer check valves. - Butterfly Valves
Used for isolation and regulation of flow. They are suitable for handling large flow volumes and are commonly installed in large pipelines. Compact and lightweight, butterfly valves offer quick operation and are relatively inexpensive, but may not provide as tight a seal as other valve types. - Needle Valves
Employed for precise flow control, especially important in fuel cells and other sensitive hydrogen applications where precise metering of hydrogen flow is required. They allow for fine adjustments of flow, but require high-quality materials like stainless steel to withstand the high pressure and avoid deformation. - Safety Relief Valves
Critical for protecting systems from overpressure by automatically releasing gas when pressures exceed safe limits. These valves are vital for safety, calibrated to open at predetermined pressure settings to prevent explosions or system failures. - Solenoid Valves
Electrically operated valves used for the automated control of hydrogen flow, suitable for remote operation. Provide rapid and reliable control but are generally used where smaller flow rates are required.
Material and Design Considerations
- Materials
Due to the risk of hydrogen embrittlement and the need for high-pressure resistance, materials like stainless steel, Hastelloy, and other hydrogen-resistant alloys are commonly used. - Design
All these valves are designed to minimise leakage, a critical factor in hydrogen systems due to the explosive nature of hydrogen. High-integrity sealing and compatibility with hydrogen are paramount.
The selection of these valves in hydrogen systems depends on the specific requirements of each application, considering factors such as operational environment, pressure, temperature, and flow characteristics. As hydrogen technology advances, continuous improvements in valve designs and materials are expected to further enhance the efficiency and safety of these systems.
