Ball Valves for Liquid Cooling Systems

Precision shut-off and flow control valves for CDU internals, branch circuits, and rack-level connections — engineered for tight spaces and reliable sealing.
Choose Your Configuration
Compact shut-off and precision control for CDU internals, branch circuits, and rack-level connections — where space and sealing are critical.
Not Sure Which Valve Fits Your Cooling Loop?
Every cooling loop has unique isolation requirements. Describe your application and our engineers will recommend the right butterfly valve type and configuration.
Our Advantages
The QINFENG Valve Difference
Fully Automated Welding
Fully Automated Welding
ISO 3834 certified automatic welding processes ensure consistent, leak-proof joints on all welded-end configurations. Every weld inspected before shipment.
Straight-Through Flow Path
Straight-Through Flow Path
Integrated forged body — ball channel and pipeline are equal-diameter. Media passes linearly with no retention, no cross-contamination. Eliminates material accumulation found in conventional ball valves.
Triple Stem Sealing
Triple Stem Sealing
Three-tier stem seal with patented anti-leak structure. Under abnormal conditions, fluid is contained within the sealing chamber — conventional valves leak from stem and body joints simultaneously.
Inline Maintenance
Inline Maintenance
Three-piece bolted body design allows on-site seat replacement without removing the valve from the pipeline. Minimizes system downtime during routine service.

Why use an integrated forged body ball valve for liquid cooling?

 
 

Integrated forged body design eliminates dead legs and external leakage paths. The straight-through full-bore flow path ensures media passes linearly with no retention or cross-contamination.

How does triple stem sealing prevent leakage in ball valves?

 
 

Three-tier stem seal with patented anti-leak structure contains fluid within the sealing chamber under abnormal conditions — conventional valves leak from both stem and body joints simultaneously.

Can ball valves be electrically actuated for automated cooling control?

 
 

Yes. Three-piece electric ball valves with proportional control enable remote flow regulation. Encapsulated seat design ensures high cleanliness with no media retention for automated CDU and pipeline operation.

How does full-bore design benefit liquid cooling ball valves?

 
 

Full-bore design ensures the ball channel and pipeline are equal diameter. Media passes linearly with minimal pressure drop — reducing CDU pump energy consumption and improving system efficiency.
