coaxial valves MK / FK direct acting

In the case of the lateral high-pressure valves, the valve drive is arranged on the side.
They are used wherever high pressures of up to 500 bar have to be controlled at high flow rates.
The high-pressure valves are available with either a magnetic or a pneumatic drive.
Among other things, the valves are used in the refueling process or in high-pressure test stands.

coaxial valves MK / FK direct acting

Compact and robust design:
Thanks to the flow-optimized, concentric arrangement of the actuator and media flow, coaxial valves are particularly space-saving and mechanically durable. They are ideal for demanding environments where reliability and longevity are essential – such as in mobile or stationary hydrogen systems.
H₂-compatible materials and high media resistance:
These valves are specifically designed for the safe handling of hydrogen, as well as aggressive, reactive, or ultra-pure media. They offer excellent chemical resistance and meet the strict requirements for tightness and material selection demanded by hydrogen applications.
Reliable operation under high pressure:
In hydrogen storage, testing, and refueling systems, high pressures are standard. Coaxial valves are developed to perform reliably under these conditions, featuring high pressure resistance and consistent switching performance.
Wide range of designs and flexible customization:
Whether 2/2-way or 3/2-way, direct-acting or pilot-operated – the broad variety of configurations enables optimal adaptation to diverse technical needs. This flexibility allows for tailor-made solutions across the hydrogen industry.
