Data Centre Valves

Data centre valves play a critical role in maintaining the stability, efficiency, and uptime of modern digital infrastructure. With servers running continuously and generating significant heat, cooling systems must operate with absolute reliability. Valves sit at the heart of these systems, controlling the flow of chilled water, coolant, air-handling circuits, and safety systems that protect sensitive equipment from overheating or failure.

What are Data Centres?

Data centres are specialised facilities designed to house the digital infrastructure that powers modern life. They contain vast numbers of servers, networking equipment, and storage systems that run everything from websites and cloud platforms to financial transactions, streaming services, and artificial intelligence workloads. Every time data is sent, stored, or processed online, it is handled within a data centre somewhere in the world. These environments are engineered for continuous operation, with redundant power supplies, advanced cooling systems, fire protection, and physical security to ensure services remain available around the clock.

Because the equipment inside data centres generates significant heat and must run without interruption, these facilities are built with extreme resilience in mind. Cooling systems regulate temperature precisely, electrical systems are backed up by generators and battery arrays, and every component is designed to minimise the risk of failure. Downtime can be enormously costly, so data centres are managed as mission-critical environments where reliability, efficiency, and control are paramount. As demand for cloud computing, AI, and digital services continues to grow, data centres have become one of the most important pieces of infrastructure in the modern world.

From characterised control valves and pressure independent valves to damper and fail-safe actuators, Belimo products provide accurate flow and airflow control across cooling plants, CRAH units, CDUs, and liquid cooling systems. Designed for continuous operation in high-load environments, these components help maintain perfect thermal balance, reduce energy waste, and protect critical IT infrastructure—keeping your data centre running at peak performance, 24/7.

Belimo Products for Data Centres

Cooling Distribution Units (CDUs) supply chilled water or water-glycol mixtures to heat-producing equipment such as servers and racks. A broad range of characterised control valves, electronic pressure independent valves, and energy valves are available to suit these systems, delivering accurate and stable flow regulation. Designed for scalability, these valves allow cooling capacity to be adjusted easily as infrastructure expands, ensuring consistent thermal performance and long-term efficiency within data centre environments.

Direct-to-chip liquid cooling, commonly known as cold plate cooling, is widely used for servers with very high thermal loads, including those supporting high-performance computing, artificial intelligence, and machine learning workloads. This method transfers heat directly from critical components into a liquid circuit, delivering far greater efficiency than traditional air cooling.

Accurate flow regulation is essential for rear-door heat exchangers (RDHx) to operate effectively. Electronic pressure independent valves and characterised control valves deliver stable, repeatable flow control regardless of system pressure changes. This level of precision ensures rear-door heat exchangers perform at their optimum, maintaining consistent cooling efficiency and thermal stability across the data centre.

Two-phase immersion cooling systems depend on tightly controlled water flow to achieve efficient condensation of the dielectric fluid. Electronic pressure independent valves maintain stable, accurate flow to the coil even when system pressures fluctuate, ensuring consistent thermal performance.

Energy valves add an additional layer of intelligence by monitoring supply and return water temperatures, calculating thermal energy in real time, and delivering clear insight into cooling performance. This makes it easier to optimise efficiency, detect inefficiencies, and maintain peak operation across the cooling system.

Computer Room Air Handling (CRAH) units deliver conditioned air into the white space, forming a core part of a data centre’s cooling strategy. They ensure a consistent airflow environment around server racks, helping maintain stable operating conditions across the facility.

Electronic pressure independent valves play a vital role within CRAH systems by delivering accurate and dependable control of water flow. This precision allows temperature and humidity levels to be regulated consistently, improving cooling efficiency while protecting sensitive equipment from thermal fluctuations.

Damper actuators play a key role within fan walls, providing accurate control of airflow to servers throughout the white space. This precision ensures that conditioned air is delivered exactly where it is needed, supporting stable thermal conditions across the data hall.

Characterised control valves and electronic pressure independent valves regulate water flow through the cooling coils, enabling consistent and effective heat transfer. Working together, these components maintain the required supply air temperatures and help create a controlled, resilient environment for sensitive IT infrastructure.

Fire and smoke actuators are critical safety components within data centres, designed to safeguard people, equipment, and infrastructure from fire-related risks. Integrated with fire and smoke detection systems, these actuators control dampers and mechanical elements that contain and limit the spread of fire and smoke during emergency conditions.

Backup generators keep servers powered during grid outages, making them a vital part of data centre resilience. Fail-safe actuators are ideally suited to regulate the combustion air required for these generators, ensuring the correct airflow is delivered under all operating conditions.

In the event of a fault, fail-safe functionality allows airflow to be shut off instantly, protecting both equipment and personnel. For installations exposed to the elements, IP66/67 (NEMA 4) rated options are available, providing reliable performance even when mounted externally on generator systems.

Central plant systems distribute chilled water throughout the entire data centre, forming the backbone of large-scale cooling operations. Because data centres demand enormous cooling capacity, these systems operate with very high flow rates and therefore require large, robust valves.

High-performance butterfly valves equipped with powerful actuators are well suited to this role, offering reliable shut-off under high pressures, minimal leakage, and durable protective housings. With IP66/67 (NEMA 4) ratings available, these valves provide dependable operation even in harsh plant environments, ensuring continuous and efficient chilled water delivery.
