Hydrogen Applications

Frequently Asked Questions

A hydrogen valve is a specialised flow-control device designed to safely isolate, regulate, or distribute hydrogen gas. It is engineered to prevent leakage and withstand the unique properties of hydrogen.

Hydrogen is highly reactive and can cause embrittlement in unsuitable metals. Hydrogen valves use stainless steel or specialist alloys to ensure long-term durability and safe operation.

Yes, many hydrogen valves are manufactured to handle high-pressure hydrogen storage, distribution, and production environments. They are tested to maintain reliable shut-off and sealing even under extreme conditions.

We supply hydrogen valves with pneumatic or electric actuators for automated control, remote operation, and integration into safety systems. Actuated packages are tested and assembled for immediate installation.

Hydrogen valves are widely used in energy storage, green hydrogen production, fuel cells, refineries, power generation, and research facilities. They also support hydrogen mobility and emerging clean energy applications.

Hydrogen valves often use PTFE, graphite, or engineered elastomers designed for low permeability. These seals help prevent hydrogen leakage, which is crucial due to its small molecular size.

Yes, ATEX-certified hydrogen valves are available for hazardous and explosive atmospheres. These ensure compliance with safety regulations in high-risk environments.

We supply manual ball valves, globe valves, needle valves, and isolation valves specifically rated for hydrogen service. These are ideal for applications requiring simple, reliable on/off control.

Selection depends on pressure, temperature, media purity, material compatibility, and whether automation is needed. Our technical team can guide you to the correct specification.

Yes, hydrogen valves built from corrosion-resistant materials are suitable for outdoor use. Weatherproof or explosion-proof actuator housings can also be supplied when automation is required.

They are available in threaded, flanged, welded, and compression-end configurations. The correct connection depends on system design and operating conditions.

Many hydrogen valves and actuated packages are stocked for quick dispatch, subject to availability. Bespoke or high-pressure assemblies can also be built with short lead times.
