Plug Valve Manufacturer
At Steel Icon Stainless Pvt. Ltd., we are a trusted manufacturer of industrial Plug Valves, engineered for tight shut-off, fast actuation, and minimal maintenance in fluid and gas control applications. Plug valves use a cylindrical or tapered plug with a passage that rotates 90° to control flow. Known for their compactness and simplicity, plug valves provide quick isolation and are particularly effective in slurry, abrasive, and high-viscosity media.
Our range includes lubricated, non-lubricated, eccentric, and lined plug valves, available in various end connections and materials. All valves are manufactured as per API 599, API 6D, ASME B16.34, and BS 5353 standards, meeting the demanding needs of petrochemical plants, pulp & paper, mining, chemical processing, and utility pipelines.

Applications
Plug valves are widely used for quick shut-off, particularly in demanding, corrosive, and slurry-based processes:
- Oil & Gas Industry – Crude handling, multiphase systems, and high-viscosity oil lines
- Chemical & Petrochemical Plants – Aggressive chemical service, solvent shut-off, and tank drains
- Mining & Slurry Pipelines – Abrasive material flow and slurry isolation
- Pulp & Paper Mills – Bleach plant and chemical dosing lines
- Marine Applications – Compact isolation valves for bilge and ballast systems
- Utilities & Power Plants – Thermal oil, gas control, and condensate recovery systems
Key Benefits
- Quick, Leak-Free Shut-Off – Provides bubble-tight sealing with quarter-turn actuation—ideal for emergency isolation.
- Minimal Flow Obstruction – Simple, straight flow path minimizes turbulence and clogging.
- Corrosion & Erosion Resistant Designs – Offered with PTFE linings, alloy overlays, or metal-to-metal seats.
- Low Torque Operation – Especially in sleeved or eccentric designs—ensures long cycle life.
- Maintenance-Friendly – Simple construction enables easy in-line maintenance and seat replacement.
Frequently Asked Questions
Explore our FAQs for insights on materials, customization, and delivery.
When should I use a plug valve over a ball valve?
Plug valves are preferred for viscous fluids, slurries, and corrosive applications where full-bore isolation isn’t necessary.
Do you offer lined plug valves?
Yes. We offer PTFE-lined plug valves for highly corrosive services such as hydrochloric acid or chlorine.
What’s the difference between lubricated and non-lubricated plug valves?
- Lubricated: Uses sealant to reduce friction; ideal for high pressure.
- Non-lubricated: Uses a sleeve or liner to reduce torque and maintenance.
Are fire-safe designs available?
Yes. We provide fire-safe and anti-static plug valves compliant with API 607 and other international standards.
