In its June 2026 article, “A Deep Dive on CoreWeave Innovations for NVIDIA Vera Rubin NVL72,” CoreWeave introduces advances in liquid cooling, networking, and rack management for next-generation AI infrastructure. The photograph of its Valvey liquid cooling valve assembly visibly features a CME-branded ball valve, illustrating an application of CME products in data center liquid cooling.

The Role of Valves in Liquid Cooling

According to CoreWeave, Valvey is a programmable, rack-level liquid cooling valve assembly that integrates flow, temperature, pressure, and leak monitoring. Working with the broader control system, it enables cooling adjustments, maintenance isolation, and emergency shutdown.

Where multiple racks share a cooling loop, individual rack isolation allows servicing or draining with less disruption to neighboring racks. This highlights the importance of valves in supporting system operation and maintenance.

CME Stainless Steel Valves for Cooling Applications

CME brings its stainless steel valve manufacturing experience to a range of fluid-handling applications, including liquid cooling. Selecting valves for these systems requires consideration of coolant compatibility, operating pressure and temperature, sealing performance, connection types, and cleanliness requirements.

CME works with customers to evaluate valve configurations, materials, seals, and inspection and testing requirements based on their specific operating conditions.

The appearance of a CME ball valve in CoreWeave's publicly showcased liquid cooling assembly provides a visible example of CME products in this evolving application. CME will continue to strengthen its manufacturing and quality control capabilities to support customers' changing fluid-control needs.
