As hydrogen infrastructure rapidly scales worldwide, the need for components that meet both transport and refueling requirements has become critical. Systems are expected to perform under extreme pressures, wide temperature ranges, and continuous cycling - while complying with multiple, highly demanding standards.
In this complex environment, Habonim H25 hydrogen valve represents a significant technological advancement as the first dual-certified valve to meet both TPED and ISO 19880-3 standards.
One Valve, Two Critical Standards
Hydrogen fueling infrastructure relies on two key operational phases:
- Transportation of compressed hydrogen.
- Dispensing at hydrogen refueling stations (HRS).
TPED – Transport Safety Compliance
The Transportable Pressure Equipment Directive (TPED) ensures safe handling of hydrogen during transport, covering:
- Tube trailers.
- Multi-element gas containers (MEGCs).
It certifies that valves can withstand:
- Mechanical stress during transportation.
- Pressure fluctuations.
- Strict international compliance requirements.
ISO 19880-3 – Refueling Performance
ISO 19880-3 defines valve performance within hydrogen refueling stations, requiring:
- High endurance (100,000+ cycles for class A).
- Leak-tight sealing under repeated operation.
- Reliable performance across temperature extremes.
The H25 uniquely meets both standards, enabling a single valve solution across the hydrogen value chain.
Engineered for Hydrogen Challenges
Hydrogen introduces specific engineering challenges that demand specialized design:
- Extremely small molecules prone to leakage.
- Hydrogen gas embrittlement (HGE) in metals.
- High-pressure operation up to hundreds of bars.
Hydrogen-Optimized Materials
The H25 is designed with materials selected to minimize embrittlement and ensure long-term durability:
- Low-hardness (on Rockwell scale) stainless steels
- High nickel, low carbon alloys
- High tensile stainless steel stems and components in critical areas
Total HermetiX Integrity package: Designed for Zero Leakage
Leak prevention is a key requirement in hydrogen systems, where even minimal emissions can impact safety and efficiency.
The H25 integrates Habonim’s Total HermetiX Integrity Package, including:
Zero fugitive-emission no maintenance stem sealing
-
Patented HermetiX™ stem sealing design with zero fugitive emission sealing capability
-
Tested or certified according to ISO 15848-1 and API 641 standards
-
Up to 500,000 cycles of operation
-
Field-proven for millions of continuous operation cycles
Double body sealing
-
Body-to-ends & body-to-bonnet double sealing for superior sealing performance
-
Selection of sealing materials for diverse applications
-
Fugitive emission prevention
Fire safe
-
According to API 607 & ISO 10497 – where applicable
-
Type-tested and certified by leading certification bodies for marine service (for selected valve series)
-
Clean fire-safe construction ensuring no graphite contamination of the media flow
Fire-Safe Design Without Compromising Purity
Hydrogen systems require both fire safety and media cleanliness.
The H25 achieves this through:
- Internal soft seals
- External graphite seals isolated from hydrogen flow for fire-safe backup
- Prevention of hydrogen-carbon interaction during normal operation
Because the interaction of Hydrogen and Graphite can generate methane, separating hydrogen from the graphite seal with the inner seal eliminates the risk of methane formation while maintaining compliance with fire-safe standards such as API 607 and ISO 10497.
Supporting Real-World Hydrogen Applications
The value of dual certification becomes evident in real applications across the hydrogen supply chain.
Transport & Distribution
- Tube trailers operating under TPED
- MEGC (Multiple Element Gas Container) - based hydrogen transport
- Mobile hydrogen delivery systems
Refueling & Dispensing
- Fixed hydrogen refueling stations (H35 systems)
- Mobile fueling stations
- Integrated industrial hydrogen systems
By using a single, dual-certified valve platform, system designers can reduce complexity and streamline compliance.
Key Features of the H25
- Dual certification: TPED & ISO 19880-3 Class A
- Pressure rating: 8,000 psi (550 bar)
- Temperature range: –40°C to +85°C
- Floating ball design
- Manual or actuated operation
- ISO 5211 actuator interface
- Multiple end connections (Cone & Thread, NPT, BSPP)
- Size range: ¼” to 1½”
Reducing Complexity, Increasing Reliability
The integration of dual certification delivers clear system-level advantages:
- Reduced need for multiple valve platforms
- Simplified engineering and procurement
- Easier compliance across international markets
- Lower maintenance and spare part requirements
For the rapidly growing hydrogen infrastructure, this level of standardization is essential for scalability and reliability.
Built for the Future of Hydrogen
As hydrogen transitions from pilot projects to large-scale deployment, the expectations for safety, durability, and performance continue to rise.
By combining:
- Transport certification (TPED)
- Refueling certification (ISO 19880-3 Class A)
- Advanced sealing technologies and hydrogen-compatible materials
The H25 provides a robust, future-ready solution for next-generation hydrogen systems.
