Flanged End Butterfly Valve

Description

Flanged End Butterfly Valve Supplier in India

Flanged End Butterfly Valve – Heavy Duty Industrial Flow Control Solution

The Flanged End Butterfly Valve is a robust, high-performance flow control valve designed for isolation and regulation of liquids and gases in industrial pipeline systems. Engineered for durability and operational efficiency, this valve is widely used in water treatment plants, chemical processing industries, HVAC systems, fire fighting pipelines, oil & gas transmission, power plants, and general industrial applications.

Unlike wafer type valves, flanged end butterfly valves come with integral flanges on both sides, ensuring secure bolted connections to pipeline flanges. This construction provides superior stability in high-pressure systems and larger diameter pipelines. It minimizes leakage risk, enhances structural strength, and simplifies maintenance.

At Krishna Industries, we supply premium quality flanged butterfly valves manufactured with precision machining and strict quality control. We position ourselves as a leading Supplier, Wholesaler, Exporter, Distributor and Trader from Ahmedabad, Gujarat, India, delivering reliable valve solutions across India and global markets.

Long Introduction – Understanding Flanged End Butterfly Valve in Detail

What is a Flanged End Butterfly Valve?

A flanged end butterfly valve is a quarter-turn rotational motion valve used to start, stop, or regulate fluid flow. The primary component is a circular disc mounted on a shaft. When the handle or actuator rotates the shaft 90 degrees, the disc either blocks or allows flow.

The flanged design incorporates full flanges on both ends of the valve body, allowing it to be bolted directly between two pipe flanges using bolts and nuts. This creates a rigid, vibration-resistant connection suitable for heavy industrial applications.

Why Choose Flanged Over Wafer Type?

While wafer type butterfly valves are compact and economical, flanged end valves provide:

• Higher structural stability
• Better alignment in large diameter pipelines
• Improved pressure handling capacity
• Easy removal without disturbing adjacent piping
• Reduced leakage risk

For critical industrial systems and high-pressure networks, flanged design is preferred.

Industrial Applications

Flanged butterfly valves are used in:

• Water supply and irrigation systems
• Effluent treatment plants (ETP)
• Sewage treatment plants (STP)
• Power generation facilities
• Oil & gas pipelines
• Chemical and petrochemical plants
• Fire protection lines
• Marine and shipbuilding industries

These valves handle water, steam, compressed air, chemicals, slurry, oil, and non-corrosive fluids.

Design Features

Heavy Duty Body Construction

The valve body is designed with reinforced ribs and thick wall sections to withstand pipeline stress and pressure variations.

Precision Machined Disc

The disc is dynamically balanced to ensure smooth operation and reduced torque requirements.

Resilient Seating

Soft seated options like EPDM and NBR ensure bubble-tight shutoff with minimal leakage.

Corrosion Resistance

Epoxy powder coating enhances resistance against corrosion and extends service life.

Low Maintenance Design

Simple construction allows easy disassembly and part replacement.

Advantages of Flanged End Butterfly Valve

• Compact design compared to gate valves
• Lightweight for large diameter sizes
• Quick quarter-turn operation
• Cost-effective compared to ball valves in large sizes
• Bidirectional flow capability
• Low pressure drop
• Long service life
