Check Valves for Liquid Cooling Systems
Backflow prevention valves for CDU pump discharge and main loop return lines — integrated welded body for zero shell leakage in continuous operation.
Every valve undergoes 100% shell hydro and seat leakage testing — zero bubbles equals zero leak. Welded joints verified by helium mass spectrometer. Spring tension and cracking pressure validated. Test reports available upon request.
* All check valves are 100% tested before shipment. Test reports available upon request.
Valve sizing by your flow and pressure specs. Material compatibility analysis for your coolant type. Custom end connections (Tri-Clamp, weld, flange). Actuator selection support (manual, pneumatic, electric).
How does a one-piece welded check valve achieve zero shell leakage?
The valve body and cover are joined by one-piece welding, eliminating the external leak path of bolted or threaded bonnets. No joint means no leak, even under continuous pressure cycling.
What is cracking pressure and why does it matter for cooling systems?
Cracking pressure is the minimum upstream pressure required to open the valve. Low cracking pressure minimizes forward flow resistance, reducing pump energy consumption in continuous cooling operation.
Can check valves function in any mounting orientation?
Yes. Spring-loaded disc design functions reliably in horizontal, vertical, or inclined mounting positions. The spring closes the disc instantly when forward flow stops or reverses.
What makes integrated check valves more compact than standard designs?
One-piece welded construction reduces overall face-to-face length compared to flanged alternatives. Compact footprint fits tight CDU pump discharge lines without additional adapters or spacers.
