Precision stainless steel valves for Secondary Fluid Networks (SFN), CDU skids, direct-to-chip liquid cooling and hygienic process industries — pharmaceutical, food, dairy and biotech.
Founded in 2008, STILONN Valves & Controls Pvt. Ltd. is a trusted Indian manufacturer of high-precision stainless steel valves — and India’s first manufacturer of SFN (Secondary Fluid Network) valves purpose-built for data center liquid cooling.
As data centers move from air cooling to liquid cooling, STILONN delivers the critical flow-control components the industry needs: butterfly isolation valves, ball valves, static balancing valves and air vent valves for CDU (Coolant Distribution Unit) skids, secondary fluid networks, direct-to-chip cooling loops and stainless steel piping systems. Our valves are trusted by leading data center operators, CDU OEMs and liquid cooling integrators across India.
Alongside our data center range, we continue to serve the industries where we built our reputation — manufacturing sanitary butterfly valves, tri-clamp ball valves, check valves, sight glasses, unions and fittings for pharmaceutical, food, dairy, cosmetics and biotech applications.
Equipped with advanced digital control machinery, modern processing systems and comprehensive in-house testing facilities, every STILONN valve is manufactured to strict quality benchmarks with full material traceability.
At STILONN, innovation drives our growth. Continuous investment in Research & Development enables us to engineer advanced valve solutions for the fast-evolving liquid cooling and hygienic process markets — in India and globally.
Our raw materials are sourced from certified suppliers and processed entirely at our own production facility near Mumbai, ensuring complete quality control at every stage — from raw material to final pressure testing.
India's first SFN valve range — butterfly isolation valves, balancing valves, ball valves and air vent valves for CDU skids, secondary fluid networks and direct-to-chip cooling.
Manufactured to ISO, DIN, IDF and SMS standards with multiple surface finishes and material options. Every valve pressure-tested with full traceability records.
Sanitary butterfly valves, tri-clamp ball valves, check valves, balancing valves, air vent valves, sight glasses, unions and fittings — 1,000+ SKUs in stainless steel.
Prompt stock availability, accurate order fulfillment and pan-India supply — supporting fast-track data center construction and process plant schedules.
AI and high-density computing are driving data centers toward liquid cooling — and every liquid cooling loop depends on reliable valves. STILONN manufactures the complete valve package for Secondary Fluid Networks (SFN): isolation, balancing, venting and check valves in stainless steel, compatible with PG25 and other data center coolants.
