Co-ax Valves Inc

Co-Ax Valves UK is part of the Muller Co-Ax AG Group, the company which first developed the coaxial valve.

Its product range ranges from simple switching valves through application-specific special valves to complete modules.

Coaxial valves from Co-Ax Valves have many advantages:

Pressure balanced design/operating from 0 bar, coaxial valves require no minimum pressure differential in order to function
Back pressure tightness – when the valve is closed, the pressure at the outlet side can be higher without any leakage
Maintenance-free and resistant to dirt – the unique design minimises wear on the valve seat even with extremely contaminated media, lasting up to 10 times longer
Fast actuation – coaxial valves are some of the fastest operating valves due to their pressure balanced design
Bi-directional operation – there is no need for multiple valves as the coaxial valve design allows the medium to flow in both directions
Compact size – the design of the valve eliminates the need for multiple actuators.

The valves are offered in 2/2 way and 3/2 way, normally closed or normally open configurations, with various options of threaded ports and flanges. There are direct acting valves to 500 bar operation and externally controlled valves to 500 bar operation. Position switches can be fitted to the valves. ATEX compliant option valves are available for use in Zone 1 environments (with switches).

SIL2 is standard on the whole valve range with SIL3 available on request on certain model types. The coaxial valves are available in manifold options for neat compact solutions, eliminating unnecessary pipework. Flow control and pressure control options, latching valves and cryogenic options are also all available.

Product Ranges

Co Axial Valves

Co-axial valves are high-performance solutions designed to handle demanding applications involving high pressure and flow. These valves feature a coaxial design, which allows for bidirectional flow, making them ideal for a variety of industries that require efficient fluid control. Available in multiple configurations, including normally open, normally closed, and double-acting models, these valves offer reliable operation with sizes ranging from 3/8" to 2" and pressure ratings up to 100 bar. They are suitable for a wide range of media, including gaseous, liquid, highly viscous, and contaminated substances. Co-axial valves are known for their durability, providing long-lasting performance with significantly reduced air consumption compared to traditional valves, offering both cost and efficiency benefits.
