Check Valves For Data Center Cooling
US Valve’s check valves for data centers were developed with efficiency in mind with the lowest pressure drop in the industry. Our all stainless steel check valves are used in Direct-to-Chip (D2C) Cooling, Rack-Level Liquid Cooling, Immersion Cooling, Rear Door Heat Exchangers (RDHx), and In-row & In-room Liquid Cooling Systems around the globe. As a leading provider of check valves for data center cooling, US Valve understands the growing needs of liquid cooling systems in data centers as they offer:
- improved cooling efficiency,
- supports higher power densities,
- reduces noise levels,
- improves energy efficiency,
- provides flexibility for expansion,
- and contributes to sustainability efforts.
Check Valves For Data Centers
Data center cooling system valves are required for several reasons:
- Preventing backflow: Check valves are designed to allow the flow of liquid in one direction while preventing backflow in the opposite direction. In data center liquid cooling systems, it’s crucial for n+1 redundancy in pumping, to ensure reliable uptime. Pumps in tandem or multiples must have a check valve placed between their discharge and the common header to provide optimal system efficiency and prevent damage.
- Protecting sensitive equipment: Data center equipment, especially servers and other electronics, can be highly sensitive to temperature variations. Check valves help maintain a consistent coolant flow in the cooling system, ensuring that the equipment is properly cooled. By preventing backflow and maintaining the desired flow direction, check valves contribute to maintaining the stability of coolant temperatures and preventing hot spots or cold spots in the data center.
- Minimizing pressure drops: US Valve check valves are designed to have minimal pressure drops when allowing forward flow. This means that they will not impede the flow of coolant significantly, when compared to competitors. By minimizing pressure drops, US Valve check valves allow the cooling system to operate at its peak efficiency, flowing nearly double the amount of coolant as competitor's valves with the same pumps. This increased flow capacity leads directly to higher thermal transfer, empowering our customers to build enclosures with the highest possible kW power ratings for tomorrow's high density computing needs.
- Compact and space-saving: US Valve check valves are compact and easily integrated into the piping of data center liquid cooling systems including rack mount CDUs, row CDUs, HDUs, heat exchangers, and immersion cooling systems. Their relatively small size allows for flexible installation in confined spaces, making them suitable for use in the limited space of data center racks as small as 2U where efficient space utilization is crucial.

Frequently Asked Questions
What kind of valves are used in a Coolant Distribution Unit (CDU)? Check valves are used at the discharge of pumps that boost the liquid coolant to the servers. Elastomer hinge check valves offer improved cooling efficiency, supports higher power densities, reduces noise, improves energy efficiency, provides flexibility for expansion, and contributes to sustainability efforts.
What is the most efficient valve to use in data center liquid cooling? Check valves are the most efficient as they minimize pressure drops while allowing the cooling system to operate at its peak efficiency. Elastomer hinge check valves allow nearly double the amount of coolant as globe or poppet valves with the same pumps.
How can you reduce pumping costs in data center direct-to-chip cooling? You can reduce pumping costs by installing an elastomer hinge check valve at the discharge of your liquid pump to allow more flow with less pressure drop.
How do you protect a coolant pump in a data center? The most common way to protect a coolant pump in a data center is to install an elastomer hinge check valve to prevent backflow.
