Every butterfly valve undergoes 100% shell hydro and seat leakage testing — zero bubbles equals zero leak. Helium mass spectrometer verifies stem and body sealing. Material confirmed by spectrometer analysis. Test reports available upon request.
* All butterfly 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).
What makes a one-piece welded butterfly valve zero-leakage?
The valve body is argon arc welded into a single integrated structure, eliminating the bolted joint between left and right body halves. Triple stem sealing with patented anti-leak design ensures zero external leakage.
How does inline maintenance work for liquid cooling butterfly valves?
Close the valve disc to isolate the branch line, remove six bolts on the branch-side flange, and service downstream components — all while the main cooling loop remains pressurized and operational.
What is the difference between one-piece, two-piece, and three-piece butterfly valves?
One-piece valves feature a fully welded body for zero leakage and inline maintenance. Two-piece valves offer lightweight, cost-effective isolation. Three-piece valves allow easy disassembly for seat replacement in branch circuits.
What standards apply to butterfly valves for liquid cooling?
Design per ASME B16.34. Hydrostatic testing per ISO 5208. Seat leakage per EN 12266-1 Class A (zero bubbles = zero leak). Tri-Clamp connections per ASME BPE, weld ends per DIN 11850.
