Frequently Asked Questions

What types of valves are used in data center liquid cooling systems?

Butterfly valves for main loop isolation, ball valves for precision shut-off, check valves for backflow prevention, and filters for particulate protection. Each type serves a specific function across CDU, pipeline, and rack-level applications.

What materials are liquid cooling valves made from?

316L and 304 stainless steel are standard for all wetted components. These materials offer superior corrosion resistance when handling water, glycol mixtures, and fluorinated coolants in continuous cooling operation.

What connection types are available for liquid cooling valves?

Tri-Clamp (sanitary quick clamp) to ASME BPE standards, butt-weld ends to DIN 11850, threaded connections for compact installations, and flanged connections for large-diameter main loop valves.

What surface finish is required for high-purity coolant compatibility?

Electropolished finish with Ra ≤ 0.4μm is standard for all wetted surfaces. This mirror-smooth finish prevents particulate shedding, eliminates micro-cracks, and ensures no coolant contamination over the system lifetime.
