All components undergo rigorous pressure and leak testing in our dedicated facilities, using advanced detection methods such as helium or hydrogen gas. Components are also cleaned and lubricated using H2-safe products in a sterile environment to prevent contamination and guarantee optimal performance in critical applications.

Engineering & Manufacturing

We can source, design, manufacture, and modify existing stock valves to optimise them for hydrogen-specific operating conditions. Our expertise ensures that each product meets stringent performance, reliability, and compliance standards, effectively addressing pressure, temperature, and media requirements.

Order management

Efficient order management is critical to our process. We track and fulfil customer orders with care, adhering to all the correct procedures and ensuring operational integrity.

Packing & Documentation

Finally, we pack each project in accordance with the customer’s requirements, including an MRB data book containing documents such as a hydrogen leak test report, a certificate of conformity for H2 service, and other related paperwork to ensure full compliance and traceability.

Hydrogen Valve Types

AC Valve Alliance offers an extensive selection of valves tailored to meet various hydrogen application requirements including hydrogen ball valves, flow control valves, pressure relief valves and more. Our Technical Manager, Nick Papworth, leads our dedicated team, we are thrilled to offer a variety of hydrogen gas valves types.

Ultra-Sensitive Hydrogen Leak Detection for Critical Safety Applications

Our diffuser sensor testing equipment detects even minimal hydrogen leaks, achieving sensitivity down to 5 x 10⁻¹¹ mbar·l/s for maximum reliability and safety. This exceptional detection capability is crucial given hydrogen’s propensity to escape through the smallest imperfections in seals and joints – leaks that would be undetectable with conventional testing methods but could pose significant safety risks over time.

The ultra-low detection threshold ensures that every valve and fitting meets the strictest safety standards before deployment, while our advanced testing protocols verify long-term seal integrity under real-world operating conditions. This level of precision testing is essential for applications where even trace hydrogen accumulation could create hazardous conditions, providing the confidence needed for critical infrastructure installations.

Hydrogen Flow, Control and Safety – Valves You Can Rely On

AC Valve Alliance is not just a hydrogen valve manufacturer – we are a problem-solving partner. Our team provides tailored solutions that address your specific media, pressure and environmental conditions. We only work with quality European valve manufacturers such as Starline, Perar, Nacional and Pekos, and offer in-house valve modifications and testing to meet project-specific criteria. We can assess your specific project needs and offer bespoke hydrogen gas valve solutions, with our team of engineers able to modify our large stock of O-rings to guarantee application suitability.

Our product range includes:

Floating Ball Valves – Ideal for standard hydrogen flow control applications due to their reliable shut-off performance and compact design. Our hydrogen floating ball valves are straightforward when it comes to operations and well-suited to low-to-medium pressure systems.

Trunnion-Mounted Ball Valves – Suited for high-pressure hydrogen gas systems, these valves are designed with a support ball to reduce operating torque and maintain hydrogen valve seal integrity under extreme pressure. They are essential where system reliability and safety are non-negotiable such as in hydrogen compression and refuelling infrastructure.

Butterfly Valves – Cost-effective and compact for hydrogen pipelines, butterfly valves are ideal for applications where space, weight and budget are considerations. With appropriate material and seal selection, they offer safe flow isolation or control in low-pressure hydrogen networks.

Line Blind Valves – For positive isolation in hydrogen production and storage, line blind valves provide a zero-leakage mechanical barrier. They are especially valuable during maintenance or emergency operations, offering visible assurance that flow is completely shut off in critical hydrogen lines.

Hydrogen Pressure Relief Valves – Essential for system safety and overpressure protection, these valves automatically release excess pressure to prevent equipment damage or catastrophic failure. They are a required safeguard in all hydrogen systems handling compressed or liquefied gas.

Hydrogen Tank Valves – Custom-engineered for secure and certified tank applications, these valves are designed to manage storage and dispensing under varying temperature and pressure conditions. We ensure full compatibility with tank materials, regulatory compliance and minimal leakage risk.

Hydrogen Flow Control Valves – For accurate modulation and flow stability, our hydrogen control valves enable precise regulation of flow rate and system pressure. This is critical in hydrogen blending, injection and processing applications where fine control ensures system efficiency and safety.

Hydrogen Valve Services

Every hydrogen project is different. That’s why we work closely with engineers, consultants and EPCs to understand their operational goals and constraints – offering not only valve supply but also bespoke manufacturing, automation, in-house leak testing and full compliance documentation. Our end-to-end support ensures each valve for hydrogen solution is tailored, traceable and ready for critical service.
