We serve CDU OEMs, hyperscale and colocation data center operators, and cooling integrators with valves proven on India’s first liquid cooling deployments — fully compatible with PG25 and glycol-based coolants for mission-critical, zero-downtime operation.
Key products: SFN butterfly valves, full-bore ball valves, static & dynamic balancing valves, dual plate NRVs, Y-strainers, air vent valves, custom CDU adapters & manifolds
2. HVAC & Building Services
For chilled water, condenser water, and hot water systems in commercial buildings, hospitals, hotels, and district cooling plants, STILONN valves deliver precise flow balancing, reliable isolation, and long service life. Our balancing valves ensure every AHU and FCU receives its designed flow, cutting energy waste across the system.
Key products: Butterfly valves, balancing valves, ball valves, NRVs, Y-strainers, air vent valves
3. Water & Wastewater Treatment
From raw water intake to RO plants, ETPs, STPs, and distribution networks, our corrosion-resistant stainless steel valves handle continuous duty in demanding water applications. Full stainless construction eliminates rust contamination and extends maintenance intervals compared to cast iron alternatives.
Key products: Butterfly valves (wafer/lug), ball valves, dual plate check valves, Y-strainers, air release valves
4. Pharmaceutical & Biotech
Our foundation industry since 2008. STILONN hygienic valves meet the strict cleanliness, surface finish, and traceability demands of pharma and biotech processing — WFI loops, purified water systems, CIP/SIP lines, and product transfer. Manufactured to ISO, DIN, IDF, and SMS standards with mirror-polish internal finishes.
Key products: Sanitary butterfly valves, sanitary ball valves, sanitary check valves, sight glasses, tri-clamp fittings & unions
5. Dairy, Food & Beverage Processing
Trusted by dairies, breweries, juice plants, and food processors across India for over 17 years. Our hygienic valve range ensures product purity, easy cleanability, and compliance with food-grade standards — from milk reception to CIP systems to final packaging lines.
Key products: Hygienic butterfly valves, sanitary ball valves, NRVs, sight glasses, SMS/IDF/DIN unions & fittings
6. Chemical & Process Industries
SS316/CF8M valves for corrosive media, solvents, and process fluids in chemical, petrochemical, paint, and specialty chemical plants. Robust construction, tested sealing, and full material traceability make STILONN valves a dependable choice for continuous process duty.
Key products: Ball valves (2-pc/3-pc), butterfly valves, Y-strainers, dual plate & swing check valves
7. Power & Energy
Cooling water circuits, auxiliary systems, and balance-of-plant piping in thermal, gas, and captive power plants rely on valves that perform under sustained load. STILONN supplies pressure-tested stainless steel valves with complete inspection documentation for power sector requirements.
Key products: Butterfly valves, ball valves, NRVs, strainers, balancing valves
8. Solar & Renewable Energy
For solar thermal plants, green hydrogen projects, and renewable energy cooling systems, STILONN provides corrosion-resistant valves built for outdoor exposure and thermal cycling — supporting India’s clean energy transition with Make-in-India manufacturing.
Key products: Ball valves, butterfly valves, check valves, air vent valves
9. Machinery & OEM Equipment
Machine builders, skid fabricators, and equipment OEMs integrate STILONN valves into their systems — from process skids to cooling modules. We support OEMs with GA drawings, STEP files, custom configurations, and reliable repeat-order supply for production lines.
Key products: Compact ball valves, butterfly valves, NRVs, strainers, custom adapters & fabricated assemblies
