USV IRX-B

The integrated IR check element responds quickly to flow changes, helping mitigate pressure spikes, water hammer, and reverse flow events.

This added layer of protection helps safeguard chips, cold plates, and other sensitive components during startups, shutdowns, and upset conditions within the CDU.​

By integrating a ball valve and an IR check valve into one compact unit, the combo valve can reduce your valve footprint by 51% or more. This frees up space in dense racks, simplifies manifold layouts, and reduces the number of fittings and joints that must be sealed and inspected.

The result is a cleaner, more compact CDU design with fewer potential leak points and faster installation.​

The combo valve’s ball element provides positive isolation for service, while the integrated IR check element prevents reverse flow during operation.

This dual-function approach reduces component count, simplifies specifying and procurement, and streamlines piping without sacrificing safety or performance.​

The Ball & IR Check Valve Combo is engineered to maintain the same high flow and low pressure drop as a standalone IR check valve.

Engineers gain the efficiency benefits of the IR design while consolidating two functions into a single component, enabling lower pump energy use and improved overall cooling performance in AI data centers.​

Application specific design with the speed and capacity to meet your growing demand:

• Compact body designs for dense manifolds and rack spaces
• Orientation and porting tailored to your piping geometry
• End Connections: Tri-clamp, NPT, Flange, wafer, or custom 
options available
• Material and elastomer selection based upon your system’s coolant 
and temperature profile
• Manual or automated actuation options for the ball isolation function

US Valve collaborates directly with OEM Engineering teams to co-design and provide rapid prototypes for seamless integration and quick validation.
