Butterfly Valve Manufacturer
At Steel Icon Stainless Pvt. Ltd., we are a trusted manufacturer of industrial Butterfly Valves, engineered for reliable shut-off, regulation, and control of fluid flow in a compact and lightweight design. These quarter-turn valves feature a centrally mounted disc that rotates with the valve stem, allowing rapid flow control with minimal pressure loss and footprint.
Butterfly valves are widely favoured in applications requiring large-diameter flow handling, low torque, and quick actuation, making them ideal for HVAC, water treatment, fire protection systems, chemical processing, power plants, and marine operations. Our valves comply with API 609, ASME B16.34, ISO 5752, and EN 593, and are available in wafer, lug, double-offset, triple-offset, and high-performance designs.
Why Choose Our Butterfly Valves?
- Compact and lightweight design suitable for space-constrained installations
- Quarter-turn operation for fast open/close functionality
- Low-pressure drop across the valve when fully open
- Available in manual, pneumatic, electric, and gear-operated actuation
- Suitable for liquids, gases, slurries, and even semi-solids
- Offered in soft-seated and metal-seated configurations for different operating conditions

Applications
Our butterfly valves are highly effective in systems that require quick shutoff and compact valve solutions, including:
- Water Distribution & Treatment – Main shutoff, pump isolation, and flow diversion
- Fire Protection & HVAC – Zone isolation and ducting systems for chilled or hot water
- Chemical & Petrochemical – For acids, bases, solvents, and vapor control systems
- Power Plants – Condensate lines, cooling systems, and turbine isolation
- Marine & Offshore – For seawater intake, ballast lines, and bilge systems
- Food & Beverage – Non-toxic seat materials available for hygienic applications
Key Benefits
- Low Installation Footprint – Ideal for large-diameter lines where space and weight are critical concerns.
- Quick Operation – Quarter-turn motion ensures fast and responsive flow control.
- Versatile Sealing Materials – Wide range of elastomer and metal seat options to match system compatibility.
- Double & Triple Offset Designs – Reduce wear, extend service life, and support high-temperature or abrasive flow conditions.
- Actuation Ready – ISO 5211 mounting pad included on most models for easy automation.
Frequently Asked Questions
Explore our FAQs for insights on materials, customization, and delivery.
What makes a globe valve suitable for flow regulation?
Its linear disc motion and perpendicular flow path create more precise control over flow rate compared to gate or ball valves.
Can globe valves be used with corrosive fluids?
Yes. With materials like SS 316, Alloy 20, and Hastelloy, they perform well with acids and aggressive chemicals.
What’s the advantage of a Y-pattern globe valve?
It offers lower pressure drop and is more compact than T-pattern globe valves—ideal for steam and thermal fluid systems.
Do you offer bellow seal globe valves?
Yes. For zero stem leakage in hazardous or toxic service, bellow-sealed valves are available.
