Siemens' new stainless steel valve expands liquid cooling offering for AI data centers
Siemens’ new stainless steel valve for AI data centers addresses evolving cooling requirements
The valve
forms part of Siemens’ broader approach to future-ready thermal infrastructure,
bringing together physical and digital technologies to support the next
generation of data centers. By
combining reliable hydronic components with scalable automation and digital
simulation, Siemens helps operators improve cooling reliability, energy performance,
and cost efficiency, while enabling partners to design, test, and deliver
integrated liquid cooling solutions faster.
“AI is fundamentally changing the thermal requirements of data centers,
with increasing compute density making liquid cooling a critical part of the
infrastructure. Our role is to help customers manage this transition reliably
and at scale. By combining proven hydronic technology with sensing, control and
intelligence, this new valve supports cooling infrastructure that can adapt as
computing requirements evolve,” said Nawfal Slimati, EVP Buildings Products at
Siemens.
Installed within the hydronic cooling circuit, it continuously measures
parameters including flow, temperature, and system performance, while actively
controlling hydronic conditions. At rack level, the valve maintains stable
differential pressure to support consistent coolant flow and protect critical
IT equipment. It reduces the risk of pressure peaks that could cause leakage or
damage to cold plates during commissioning, operations, and maintenance. It
also adapts automatically when servers or complete racks are added, removed, or
replaced.
The valve integrates local control loops that can operate independently
of the coolant distribution unit controller. Automatic presetting and open
communication interfaces enable faster commissioning and flexible integration into
broader automation and monitoring systems. This helps operators respond to
changing cooling demands while improving visibility into system performance and
supporting more automated and self-adapting data centers. It is compatible with
water, water ethylene glycol, and water propylene glycol cooling media.
