H12 Vertical Liquid Cooling Check ValveOverview

The H12 Vertical Liquid Cooling Check Valve is an automatic valve designed specifically for data center liquid cooling cabinets, cooling tower circulation systems, and compact liquid cooling pipelines. Utilizing a vertical lift structure, the valve opens automatically under medium pressure and closes via the disc’s weight and backflow. For liquid cooling applications, the body is precision-cast from high-grade stainless steel with a hydrodynamically optimized disc, ensuring sensitive operation even in low-pressure differential environments to prevent backflow damage to pumps and precision electronics.

H12 Vertical Liquid Cooling Check ValveCharacteristic

1、Vertical Guided Structure: The unique vertical lift design ensures the disc moves smoothly along the guides for accurate resetting during closure.

2、Ultra-Low Cracking Pressure: Optimized disc weight for low-pressure cooling loops ensures rapid opening upon pump startup, reducing system energy consumption.

3、Dead-Zone Free Cavity: Smooth internal surfaces prevent sediment accumulation, compatible with deionized water and glycols to maintain system cleanliness.

4、Compact Threaded Connection: Standard female threads allow for a small footprint, ideal for space-constrained cooling modules or Cooling Distribution Units (CDU).

5、Quiet Closure Design: Precision-ground disc and seat (with optional soft seals) effectively absorb vibration and noise, suitable for quiet office or server room environments.

6、Corrosion-Resistant & Durable: All-stainless steel construction withstands frequent thermal cycling and prevents ion contamination, extending the maintenance cycle.
