Exact Specification for Demanding Environments

Standard valves were never engineered for hyperscale liquid cooling. US Valve’s patented IRX® Check Valve and IRX-B Ball Valve deliver higher flow, lower pressure drop, zero external leak paths, and exact-spec configurability for CDU architectures powering the world’s most demanding data centers.

Whether you’re optimizing thermal performance, protecting uptime, or sourcing to exact requirements, US Valve delivers the engineered valve platform built for modern liquid cooling systems.

IDEX-Backed Manufacturing

Global capacity. Reliable delivery.

As Rack Densities Rise, Every Component Matters

AI workloads have pushed rack densities beyond the limits of traditional cooling methods. Liquid cooling isn’t optional anymore. But many CDU systems still rely on valve designs originally developed for industrial applications, not for modern thermal infrastructure.

Choose US Valve and Leave These Challenges Behind

Pressure Drop

Conventional valves force pumps to work harder and reduce overall system efficiency.

Leak Paths

External retention methods create additional failure points inside critical cooling loops.

Space Constraints

Bulky valve footprints limit CDU design flexibility.

Supply Chain Risk

Long lead times and limited configurations delay deployment schedules.

One Valve Platform. Two Critical Functions.

US Valve developed the IRX and IRX-B using the same engineering philosophy:

  • Internally retained designs
  • Ultra-low restriction flow paths
  • High usable Cv
  • Zero external leak paths
  • Compact footprint
  • Exact-spec configurability

Together they create a complete fluid management platform for CDU applications.

Higher Usable Cv Across Real Operating Conditions

Not theoretical performance. Actual performance. IRX delivers 2x-6x higher usable Cv than conventional poppet-style check valves.

The Result
  • Lower pressure drop
  • Reduced pump energy
  • Improved thermal efficiency
  • Better system-wide performance
