• Seat Material: Commonly EPDM, NBR, or PTFE for leak-tight sealing.

• Design: Wafer type, installed between flanges (ANSI, DIN, BS, IS standards).

• Operation: Manual lever, gear-operated, pneumatic actuator, or electric actuator.

• Pressure Rating: Typically PN10/PN16 or Class 125/150.

• Size Range: DN 40 mm to DN 1200 mm (varies by manufacturer).

• Coating: Fusion-bonded epoxy or enamel for corrosion protection.

🔹 Advantages:

• Lightweight and compact compared to other valve types.

• Cost-effective and easy to install.

• Provides quick shutoff (90° turn).

• Low pressure drop and high flow capacity.

• Suitable for both on/off and throttling service.

🔹 Applications:

• Water treatment plants

• HVAC systems

• Firefighting systems

• Irrigation and agriculture

• Food & beverage industry

• General industrial fluid handling

Product Details:

A Double Flanged Butterfly Valve is a quarter-turn valve designed with flanges on both sides, allowing it to be directly bolted between pipeline flanges. This design provides extra strength, rigidity, and ease of installation, making it suitable for large-size pipelines and high-pressure applications. Unlike wafer or lug types, the double flanged design ensures perfect alignment and secure sealing, especially in heavy-duty water and industrial systems.

🔹 Key Features:

• Body Material: Cast Iron, Ductile Iron, Carbon Steel, or Stainless Steel.

• Disc Material: Ductile Iron, Stainless Steel, Aluminum Bronze, or coated options (epoxy/Ni-plated).

• Seat/Liner: EPDM, NBR, PTFE, Viton (depending on fluid compatibility).

• Design Standard: AWWA C504, BS, DIN, or IS standards.

• End Connection: Double flanged (drilled as per ANSI, DIN, BS, IS standards).

• Size Range: Typically DN 100 mm to DN 3000 mm.

• Pressure Rating: PN 6, PN 10, PN 16, PN 25 (depending on design).

• Operation: Lever, Gearbox, Pneumatic actuator, or Electric actuator.

• Coating: Fusion-bonded epoxy or enamel coating for corrosion protection.

🔹 Advantages:

• Stronger and more rigid than wafer or lug types.

• Suitable for large-diameter and high-pressure pipelines.

• Provides bubble-tight shutoff and low pressure drop.

• Easy installation and dismantling with bolted flange ends.

• Long service life and minimal maintenance.

🔹 Applications:

• Water treatment & distribution systems

• Sewage and wastewater plants

• Irrigation and flood control projects

• Power plants & HVAC systems

• Chemical and process industries

• Firefighting systems
