Key Features:

1. Ductile Iron Construction:

   • High Strength: Ductile iron provides superior mechanical properties, including high tensile strength and impact resistance, ensuring durability in demanding environments.

   • Corrosion Resistance: The material offers excellent resistance to corrosion, making it suitable for water and wastewater applications.

   • Cost-Effective: Ductile iron is a cost-effective material that balances performance and affordability.

2. Flange End Connection:

   • Secure Installation: The flange end connection ensures a strong, leak-proof joint, making it easy to install and integrate into existing piping systems.

   • Versatility: Compatible with various flange standards (e.g., ANSI, DIN, JIS), allowing for use in a wide range of applications and regions.

3. Lever Operator:

   • Simple Operation: The lever operator provides easy and efficient manual control, allowing for quick opening and closing of the valve.

   • Visual Indication: The lever position clearly indicates whether the valve is open or closed, ensuring straightforward operation and monitoring.

4. Butterfly Valve Design:

   • Efficient Flow Control: The butterfly valve design allows for full, unobstructed flow with minimal pressure drop, making it ideal for applications requiring efficient flow regulation.

   • Compact and Lightweight: The compact design reduces space requirements and makes the valve easy to handle and install.

5. Resilient Seat:

   • Bubble-Tight Seal: The resilient seat (typically made of EPDM, NBR, or other elastomers) ensures a tight, bubble-tight seal, minimizing leakage and providing reliable performance.

   • Wide Temperature Range: The seat material is suitable for a range of temperatures, depending on the specific elastomer used.

6. Bi-Directional Sealing:

   • Versatility: The valve is designed to handle bidirectional flow, making it suitable for applications where flow direction may change.
