Capabilities
Engineered Flow Control for the Liquid Cooling Era
From design to commissioning — STILONN designs, manufactures, tests, and supplies stainless steel valves, manifolds, and prefabricated piping systems for AI data centers, liquid cooling, and critical process industries.
STILONN Valves & Controls is a professional OEM for Liquid Cooling Valves, CDU Valves, SFN Valves, Stainless Steel Manifolds, and Prefabricated Piping Systems for modern AI and data center cooling applications. With complete in-house capability across design, manufacturing, fabrication, and testing — and a manufacturing capacity of 120,000 units annually across three units — we take full ownership of your flow control scope, from first drawing to final commissioning.
