Hydrogen Products
Hydrogen Valves, Fittings & Components
Hydrogen‑Compatible Materials
BuTech hydrogen valves and components are constructed from high‑performance 316 stainless steel with a minimum 12.5% nickel content, specifically selected to resist hydrogen embrittlement and maintain long‑term material integrity in hydrogen service.
Engineered for Hydrogen Service
Products are purpose‑designed for gaseous hydrogen applications, addressing challenges related to small molecular size, diffusivity, and repeated pressure cycling commonly found in hydrogen systems.
Leak‑Tight Sealing Performance
BuTech hydrogen valve designs focus on reliable containment through optimized valve geometries, chevron packing systems, and sealing concepts intended to deliver consistent, leak‑tight performance in hydrogen gas service.
Standards‑Based Validation
Hydrogen‑rated designs have been tested in accordance with applicable ISO hydrogen standards, including extensive pressure cycling using hydrogen‑relevant gases to verify sealing and packing durability.
Medium‑ and High‑Pressure Capability
BuTech hydrogen components are suitable for medium and high‑pressure hydrogen environments, supporting demanding operating conditions across production, storage, transfer and dispensing systems.
Broad Hydrogen Applications
Hydrogen‑qualified products are used across hydrogen compression, storage, transfer, and dispensing systems, including refueling infrastructure, fuel cell testing, gas distribution and R&D environments.
Why Operators Choose BuTech for Hydrogen?
✅ Designed Around Hydrogen Risk, Not Adapted Later
BuTech hydrogen solutions are developed with hydrogen service as a primary design requirement, addressing material behavior, sealing performance, and long‑term reliability from the outset rather than adapting general‑purpose valve designs.
✅ Built for Infrastructure‑Scale and Testing Environments
From hydrogen refueling stations and compression systems to fuel cell testing and R&D facilities, BuTech supports hydrogen applications where consistency, repeatability and operational confidence are essential.
✅ Engineering Support for Application‑Specific Requirements
Hydrogen systems often involve unique operating conditions and regulatory considerations. BuTech provides application‑level support to help operators align product selection with system demands and safety expectations.
✅ Integrated Within a Broader High‑Pressure Ecosystem
BuTech hydrogen valves and components are part of a wider portfolio of high‑pressure technologies, supporting seamless integration with compression, storage, transfer and control systems.
