- Energy-efficient: Low energy consumption, cost-saving.
High-pressure coaxial valve VMK-H
- High pressure resistance (up to 200 bar)
- The VMK has been specially developed for applications with extreme pressures and can withstand up to 200 bar. This makes it ideal for demanding industrial environments where conventional valves reach their limits.
- Compact design
- The axial flow design makes the valve particularly space-saving and allows for easy integration into existing systems. This design also ensures even pressure distribution and reduces wear.
- Override-controlled switching mechanism
- The valve is operated by a pilot control, which ensures safe and precise switching even at high differential pressures. This increases operational reliability and ensures reliable functioning under difficult conditions.
- Long service life and low maintenance
- Thanks to high-quality materials and a well-thought-out design, the VKH10 has an impressively long service life. The robust construction minimizes maintenance and reduces downtime in operation.
- Versatile media compatibility
- The valve is designed for a wide range of media, including gases, liquids and hydraulic oils. This makes it flexible for use in a variety of industries and offers a wide range of applications.

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.
