Key Features:

1. Three Eccentric Design:

   • Bubble-Tight Seal: The triple offset (three eccentric) design eliminates friction between the disc and seat during operation, ensuring a tight, bubble-tight seal and zero leakage.

   • Reduced Wear: The eccentric design minimizes wear on the sealing surfaces, extending the valve's service life and reducing maintenance costs.

2. Metal-to-Metal Seal:

   • High-Temperature and High-Pressure Resistance: The metal seat provides excellent performance in extreme temperatures and pressures, making it suitable for critical applications.

   • Durability: The metal seal is highly resistant to corrosion, erosion, and wear, ensuring long-term reliability in harsh environments.

3. Butt-Welded Connection:

   • Leak-Proof Installation: The butt-welded end connection ensures a strong, permanent, and leak-proof joint, ideal for high-pressure piping systems.

   • Structural Integrity: Provides superior strength and stability, making it suitable for high-stress applications.

4. Worm Gear Operator:

   • Precise Control: The worm gear mechanism allows for smooth and precise operation, enabling accurate positioning of the valve disc.

   • Mechanical Advantage: The gear-driven design provides high torque output, making it easier to operate the valve in high-pressure or large-diameter applications.

5. API Compliance:

   • API 609 Standard: Designed and manufactured in compliance with API 609 standards, ensuring high-quality performance and reliability for industrial applications.

   • Interchangeability: Meets international standards for compatibility with existing systems and components.

6. Bidirectional Sealing:

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

Advantages:

• Zero Leakage: The three-eccentric design and metal-to-metal seal ensure a bubble-tight seal, even under extreme conditions.

• High Durability: Constructed from high-quality materials, the valve offers exceptional resistance to wear, corrosion, and high temperatures.

• Precise Operation: The worm gear operator provides smooth and accurate control, ensuring optimal flow regulation.

• Robust Installation: The butt-welded connection ensures a strong, leak-proof, and permanent installation.

• API Compliance: Meets API 609 standards, ensuring reliability and compatibility with industrial systems.
