High-pressure lateral hydrogen valve up to 1000 bar KX1000
- coax® KX1000 Compact valve for H2 high-pressure applications up to 1000 bar
- Compact design
- Large nominal diameter enables very fast filling and emptying times
- Can be flowed through on both sides
- Seals on both sides
- Durability and reliability
- Safety and leak-tightness
High-pressure hydrogen lateral valve up to 1000 bar KX1000
- Compact: Extremely compact design and suitable for 100% hydrogen applications. Thanks to its pressure-balanced design, the valve offers maximum flow with minimum dimensions. This makes it particularly suitable for use in confined installation situations.
- Efficient: large nominal width enables very fast filling and emptying times. The large nominal width of the KX 1000 will reduce refuelling times, which is particularly important in view of the fact that H2 filling stations are expected to handle significantly larger refuelling volumes in the future. This leads to a significantly improved level of utilisation and increased efficiency.
- Bi-directional flow: The unique pressure-balanced design of the KX1000 valve allows flow in both directions at any pressure stage, while providing a tight seal at the valve seat. The externally controlled valve requires only a fraction of control air per stroke and works reliably from a control air pressure of just 6 bar.
- Sealed and secure The valve is bubble-tight at the valve seat up to 1000 bar.
- Long service life and system reliability: The valve has adjustable outlet throttles to open or close it more slowly. Two inductive end switches also enable reliable monitoring of the switch position, which further improves operational reliability.
- Safety and environmental friendliness The KX1000 valve is suitable for use in ATEX areas where there is a risk of explosion.

coax® – Valve Technology that Drives the Hydrogen Future
müller co-ax gmbh delivers cutting-edge valve solutions for every stage of the hydrogen value chain – from production to application:
- Hydrogen production / electrolysis
- Storage
- Transport
- Refueling
- Test benches
Our coax® valves are specifically engineered for hydrogen-based systems. They combine a compact design, high flow rates, wide pressure ranges, and the use of hydrogen-resistant materials – making them ideal for installation in tight or space-constrained environments.
With integrated limit switches, valve positions (open/closed) can be directly and reliably detected – a critical feature for automated systems and safety-relevant applications.
A standout feature: The magnetically operated coax® valves are uniquely designed to remain leak-tight to the atmosphere even if the seals begin to wear. In other words, there is no operational connection to the external environment – ensuring zero hazardous leakage, no skin contact with media, and maximum operational safety.
These closed valve assemblies are the perfect choice for demanding media such as gaseous hydrogen, liquid ammonia, or methanol – and are ideally suited for use in explosive environments.
