The coaxial valves from müller co-ax feature a pressure-relieved design and highly reliable switching behavior – regardless of whether they are used under vacuum, low, or high pressure. The compact design, the high switching speed, and the robust construction makes them the perfect solution for demanding applications in a wide variety of industries.
Here you will find an overview of our coaxial valves—ranging from direct-acting to pilot-operated models in various sizes and pressure ratings. All valves are based on the same operating principle and offer structural advantages such as high tightness, low susceptibility to wear, and bidirectional flow.

Electrically operated 2/2-way coaxial valves have two ports and two operating positions. They are hermetically sealed and are particularly suitable for liquid, gaseous, contaminated, or critical media. Their design ensures that no process medium escapes to the outside, even as the seals wear down.
2/2 Way coaxial Direct Acting Valves
These electrically operated 3/2-way coaxial valves feature three ports and two operating positions. Thanks to their hermetically sealed design, they are suitable for demanding media — from gases to contaminated or toxic substances. Even in the event of wear, the external seal remains intact.
3/2 Way coaxial Direct Acting Valves
2/2-way pilot-operated coaxial valves are pneumatically or hydraulically actuated and feature two ports and two operating positions. They are controlled via an integrated pilot valve or an external valve terminal. Adjustable switching times allow for precise delay and help reduce pressure spikes in piping systems.
2/2 Way coaxial Externally Controlled Valves
The FMX series comprises compact, externally controlled coaxial valves designed for applications with demanding requirements for installation space and flexibility. Thanks to their design, they are particularly well-suited for use in valve blocks or manifolds. They combine the typical advantages of the coaxial design with space-saving integration into complex systems.
2/2 Way coaxial Externally Controlled FMX Series
3/2-way externally controlled coaxial valves are pneumatically or hydraulically operated and feature three ports and two switching positions. They are controlled via a pilot valve or existing valve terminal. Fine-tuning valves can be used to adjust the switching times in order to specifically prevent pressure surges in the system.
