How Data Centers Stay Cool:

The Role of Enolgas USA's 13214 Actuator and

17002 Stainless Steel Valve

The Heat Problem No One Talks About

Every time you stream a video, send an email, or ask an AI a question, somewhere in the world a server is generating heat — a lot of it. Data centers are among the most energy-intensive buildings on the planet, and the number one reason for that is cooling. Servers run hot. Left unchecked, heat leads to hardware failures, costly downtime, and cascading outages that can affect millions of users at once.

According to the U.S. Department of Energy, data centers account for roughly 2% of total U.S. electricity consumption, and a significant portion of that energy goes directly toward keeping equipment cool. As artificial intelligence and cloud computing continue to grow, so does the demand for smarter, more reliable cooling infrastructure.

That's where precision flow control comes in — and where Enolgas USA's products are making a real difference.

How Data Center Cooling Actually Works

Most modern data centers rely on chilled water systems to manage heat. In these systems,

cold water — typically maintained between 45°F and 55°F — is pumped from a central chiller plant through a network of pipes to air-handling units or direct liquid cooling systems positioned near the server rows. These units extract heat from the air (or directly from the hardware), and the now-warmer water returns to the chiller to be cooled again and recirculated.

The key to an efficient system is control. Cooling circuits must be switched on or off rapidly in response to changing thermal loads — when servers ramp up under peak demand, chilled water flow must open quickly and reliably. When demand subsides, stainless steel valves close to prevent overcooling and wasted energy. Fast, dependable on/off actuation is the backbone of this entire process.

The Enolgas USA Solution:

13214 Series Actuator + 17002Stainless Steel Valve

Enolgas USA's 13214 Series Electric Actuator paired with the 17002 Stainless Steel Ball Valve is purpose-built for exactly this kind of demanding, fast-response application. Together, they function as a high-performance automated valve assembly — the 17002 stainless steel valve controls the flow of chilled water, while the 13214 actuator opens or closes it in just 5 seconds on command from the building management system (BMS) or data center infrastructure management (DCIM) platform.

The 13214 Series Actuator

The 13214 is a 24V DC electric actuator in the flat ISO form factor, engineered for HVAC and building automation applications where speed and reliability are non-negotiable. Key features that make it well-suited for data centers include:

24V DC Power Supply & On/Off Control — The 13214 operates on a safe 24V DC supply— the standard voltage used throughout modern building automation infrastructure — and delivers clean, definitive on/off actuation. When 24V is applied to the green wire, the

stainless steel valve opens; remove the signal, and it closes. Simple, fast, and rock-solid in

operation.

5-Second Running Time — The actuator strokes from fully closed to fully open — or back— in just 5 seconds. In a data center where a spike in server temperature demands

immediate cooling response, that speed matters. Five seconds is the difference between a

thermal event and a non-event.

ISO 5211 F03 Quick-Mount Connection — The 13214 mounts directly to the 17002

stainless steel valve via the standardized ISO 5211 F03 interface, eliminating the need for

special adapters or custom brackets. In a large data center where hundreds of such

assemblies may be installed, that ease of installation translates directly into labor savings

during commissioning and maintenance.

Integrated Limit Switches with Auxiliary Contacts — The actuator includes built-in limit

switches that confirm the stainless steel valve's open and closed positions back to the BMS

— a gray wire signals "valve open" and a pink wire signals "valve closed." These N.O.

auxiliary contacts (rated 250VAC 10A) allow the BMS to verify that every valve in the

system has responded correctly, enabling automated fault detection if a valve fails to

actuate.

IP54 Ingress Protection — Data center mechanical rooms can be humid and dusty

environments. The 13214's housing carries an IP54 rating, protecting against dust ingress

and water spray from any direction — ensuring the electronics remain reliable over years of

continuous operation.

12W Power Consumption — At only 12 watts, the 13214 is an energy-efficient choice.

Across hundreds or thousands of actuated stainless steel valve assemblies in a hyperscale

facility, that low draw adds up to meaningful savings on the facility's electrical overhead.

The 17002 Stainless Steel Ball Valve

The 17002 is an Enolgas stainless steel ball valve engineered to pair directly with the 13214

actuator through the ISO 5211 interface, forming a matched, reliable automated assembly.

Stainless steel construction makes the 17002 an ideal choice for the demanding conditions

inside data center cooling loops. Key advantages include:

Full Bore Design — No internal restriction means lower pressure drop across the stainless steel valve. In a system with hundreds of valve assemblies in series and parallel, every PSI of pressure drop adds up — full bore stainless steel valves help the chiller plant work more efficiently and reduce pump energy consumption.

Stainless Steel Durability — Stainless steel construction gives the 17002 exceptional

resistance to corrosion, scale, and the chemical treatments commonly used in chilled water

loops. Where brass or carbon steel valves may degrade over time in treated water systems,

the 17002 stainless steel valve maintains its integrity — reducing the risk of leaks, failures,

and unplanned maintenance.

Seamless Actuator Compatibility — The 17002 stainless steel valve is engineered to

interface directly with Enolgas actuators through the ISO 5211 quick-mount connection.

The low operating torque required to turn the stainless steel ball means the 13214 actuator

can cycle the valve repeatedly — thousands of times over its service life — without undue

mechanical wear on either component.

Continuous Duty Performance — Built for hot and cold water applications, the 17002

stainless steel valve is designed for the continuous duty cycles that data center cooling

demands. These stainless steel valves may open and close multiple times per day, every

day of the year — and they are built to handle it without compromise.

Integration with Building Management Systems

In a modern data center, the actuator and stainless steel valve assembly doesn't operate in

isolation — it's one node in a complex network of sensors, controllers, and software platforms. Here's how a typical integration works:

• Temperature Sensors detect real-time conditions at the server rack level. If inlet air

temperature at a rack rises above a set threshold, the BMS registers a cooling demand.

• The BMS or DCIM Platform sends a 24V DC on/off signal over standard low-voltage

wiring to the 13214 actuator's green control wire.

• The 13214 Actuator receives the signal and drives the 17002 stainless steel valve from

closed to fully open in 5 seconds, immediately increasing chilled water flow to the affected

cooling unit.

• The Integrated Limit Switches confirm to the BMS that the stainless steel valve has

reached its commanded position — open or closed — providing closed-loop verification

and enabling alarm conditions if the valve fails to respond correctly.

• When the Thermal Load Drops, the BMS removes the 24V signal. The 13214 drives the

stainless steel valve closed in 5 seconds, shutting off chilled water flow and preventing

energy-wasting overcooling.

The result: stainless steel valve assemblies open and close in seconds to match real-time heat loads, server temperatures stay within safe ranges, and the chiller plant operates only as hard as the facility actually demands — saving energy without sacrificing reliability.

Why Speed and Reliability Matter in Mission-Critical Environments

Data centers operate under Service Level Agreements (SLAs) that promise customers

extraordinary uptime — often 99.999%, meaning less than six minutes of unplanned downtime per year. A cooling failure doesn't just degrade performance; it can trigger automatic server shutdowns to prevent hardware damage, causing an outage that violates those SLAs and costs operators millions of dollars per hour.

Fast, reliable on/off actuation of a high-quality stainless steel valve is a front-line defense

against that scenario. A 5-second stroke time means that from the moment a BMS detects a

temperature excursion to the moment cooling water is flowing through the stainless steel valve, only seconds have passed. An actuator that responds sluggishly, a stainless steel valve that sticks, or an assembly that fails to confirm its position to the BMS all represent risks that no data center operator can afford.

That's why Italian-engineered quality — backed by Enolgas Bonomi's ISO 9001 certification

since 1991 and 65 years of manufacturing expertise — matters in this application. Every 13214 actuator and every 17002 stainless steel valve is produced to tight tolerances, tested before it ships, and designed to perform reliably through years of continuous cycling.

A Partnership Built for Scale

Data centers are not built one at a time. A hyperscale facility may house thousands of cooling circuits, each requiring its own stainless steel valve assembly. The economics of installation and maintenance at that scale favor solutions that are fast to install, easy to service, and consistent in performance across every unit.

Enolgas USA's single-item-number system — where the actuator and stainless steel valve ship together as a matched assembly under one part number — simplifies procurement, reduces inventory complexity, and ensures that every unit on the floor is spec-identical. The ISO 5211 standardized interface means replacement stainless steel valve assemblies drop in without any guesswork about compatibility, minimizing maintenance time in a facility where every minute of downtime carries a cost.

Conclusion: Cool, Controlled, and Connected

As data centers grow more sophisticated and energy efficiency becomes both a business and regulatory priority, the components inside the mechanical room matter more than ever. The Enolgas USA 13214 Series Actuator and 17002 Stainless Steel Ball Valve deliver the speed, reliability, and ease of integration that mission-critical facilities demand — opening and closing the stainless steel valve in just 5 seconds, confirming position back to the BMS, and doing it thousands of times over a long service life without missing a beat.

From the chiller plant to the server rack, every degree of temperature and every gallon per

minute of flow is an opportunity to do better — to waste less energy, protect more hardware,

and keep the digital world running without interruption.
