Data Centers | Cooling Systems | KITZ Corp. of America

KITZ Corporation of America provides high-performance valve solutions that support critical data center systems. Our portfolio—including stainless steel and specialty alloy HVAC ball valves, check valves, and resilient seated and high performance butterfly valves—is engineered for demanding applications such as HVAC cooling, liquid cooling distribution, and facility water systems. Our valves contribute to the data center’s larger operational strategy of maximum uptime and resilience.

OVERVIEW

The global expansion of data centers—driven by AI, cloud computing, and high-density processing—has elevated the importance of infrastructure that can operate around the clock. Uptime is not supported by a single system but by a coordinated network of mechanical, electrical, and life-safety systems working in parallel. Within this ecosystem, valves play a critical role across cooling, water distribution, fire protection, and fuel handling systems so that each one performs as intended under constant demand.

Correctly specified and strategically placed valves directly influence system efficiency, maintainability, and long-term performance. Valve material selection and construction must align with service conditions (e.g., clean water, seawater, or chilled water) for durability and consistent operation over time.

The Shift to Advanced Liquid Cooling

Emerging Data Center Trends

The data center industry is experiencing a significant shift in cooling architecture. As GPU densities rise to support AI workloads, traditional air-cooled systems are being supplemented or replaced by advanced direct liquid cooling (DLC) methods. This evolution creates a critical need for high-volume, reliable suppliers that can provide precision valves for both legacy air handling and next-generation liquid cooling manifolds.

With the demand for hyperscale facilities growing rapidly, the ability to source consistent, high-performance components at scale is necessary for meeting aggressive construction and deployment schedules.

Applications

Key Applications of Valves in Data Centers

Valves are foundational to how data centers operate, serving critical functions across every major system, from thermal management and liquid cooling to fire protection and life safety. Whether regulating flow in facility water lines or controlling coolant through high-density server racks, the same core valve components enable the precise control, isolation, and reliability that keep these facilities online around the clock.

Valves are integrated across both mechanical and utility infrastructure, including central plants, distribution loops, and point-of-use equipment. They are used to start, stop, balance, and redirect the flow of liquids and gases so that each system performs as designed under continuous load conditions. Their placement allows operators to isolate sections for easy maintenance, quickly respond to system changes, and maintain redundancy without interrupting operations.

Computer Room Air Conditioning (CRAC) and Air Handling (CRAH) Systems

Accounting for nearly 50% of total data center power usage, thermal management is one of the most valve-intensive functions in a data center. Chilled water systems rely on butterfly valves and other valve types to control the flow of coolant between central plants, cooling towers, and IT spaces. Within computer room air conditioning (CRAC) and computer room air handling (CRAH) units, valves regulate water flow to cooling coils, maintaining stable temperatures required for server performance.

At the distribution level, valves balance and isolate flow throughout chilled water loops, ensuring consistent delivery to air handling units (AHUs) and in-row cooling systems. This level of control is essential for managing variable loads and preventing hotspots in high-density server environments.

Because of the critical nature of data center cooling, butterfly valves installed in HVAC systems are typically rated for up to three times more volume than those in standard office building piping. They precisely regulate and isolate the flow of chilled water to cooling coils and air handling units (AHUs), supporting the fast, consistent removal of heat from server rooms.

Direct Liquid Cooling (DLC) Systems

As compute density increases—particularly with AI-driven GPU workloads—direct liquid cooling is becoming more prevalent. In these systems, valves control coolant flow from coolant distribution units (CDUs) directly to server racks. They can isolate individual racks or loops, supporting maintenance and scalability without disrupting adjacent systems.

Air-cooled infrastructure and liquid cooling systems increasingly operate in parallel, with valves coordinating flow across both.

Fire Protection Systems

Valves play a critical role in fire protection systems, including sprinkler and pre-action configurations commonly used in data centers. These isolation valves control the release and isolation of water in response to fire detection events while preventing accidental discharge in sensitive IT environments. Reliable valve operation is essential to meet code requirements and protect critical assets without introducing unnecessary risk.

Water Supply and Treatment Systems

Beyond cooling and fire protection, isolation valves are used throughout facility water systems, including make-up water lines, filtration, and treatment processes. They regulate flow to and from cooling towers, manage chemical dosing systems, and support water conservation strategies. Proper valve selection prevents internal scaling and galvanic corrosion, which are critical for maintaining the high-purity water standards of data center cooling towers and heat exchangers.

Backup Power and Fuel Handling

In facilities with on-site power generation, valves are used in fuel storage and delivery systems for generators. They control fuel transfer, enable system isolation, and support safe operation during both routine testing and emergency deployment. Specific areas that depend on valves include:

Fuel gas skids. Valves are required to isolate, filter, and regulate the pressure of natural gas before it enters the turbine. KITZ’s high-pressure ball and gate valves are standard for these isolation points.
Emergency shutdown (ESD). Actuated ball valves are used in safety loops to rapidly cut off fuel supply in the event of a system fault or fire.
Purging systems. Small-bore ball valves are used in nitrogen or air purging lines to clear fuel from the system during maintenance or shutdowns.
Cooling systems. Large turbines often use water-cooled components or are part of a Combined Cycle (CCGT) plant where heat is recovered to produce steam. KITZ’s high-temperature cast steel valves are used in these steam cycles.

THE KITZ ADVANTAGE

Overview of KITZ Valves in Data Centers

Valve selection directly impacts system responsiveness, efficiency, and resilience, making it a critical consideration in both design and operation. Redundant piping is a vital element of mission-critical data center infrastructure and 24/7/365 operation.

KITZ manufactures HVAC butterfly valves, ball valves, and check valves to support systems in new and retrofitted data centers, providing the following benefits:

Cost-effective & compact

Compared to gate or globe valves, our butterfly valves are more cost-effective and have a smaller physical footprint. This makes them ideal for confined-space installations with a tightly designed array of hardware or retrofits with limited available space.

Easy integration with automated control systems

Our butterfly and ball valves are easier to automate in hydronic systems, as they only require quarter-turn rather than multi-turn actuation. Automated control allows for easy remote temperature regulation, emergency shutoff, and general flow balancing in building management systems (BMS).

Bubble-tight shutoff

Our butterfly and ball valves achieve bubble-tight shutoffs in key areas, such as manifolds and CDUs. Our PTFE seating material is a must-have in server environments, which must be protected from leaks.

Time-tested performance

Data centers rely on our butterfly valves for their consistent, efficient performance with minimal maintenance.
