Delayed Coker Unit- Double Disc Gate Valve
- Ideal for critical service lines requiring high reliability and efficient sealing.
- Designs: Flat body ensures full coverage of seat surfaces in both open and closed positions. “Floating” sealing design unaffected by thermal stress or pressure deformations.
- Sealing System: Two independent sealing discs provide true “Block and Bleed” functionality. Active mechanical seating force in the closed position for double block and purge.
- Operation: Differential pressure between purge steam and line pressure tightens the valve, minimizing purge steam consumption. Valve tightens after opening to prevent water or coke ingress.
- Purging: Steam purging ensures 100% positive shut-off and prevents particle entry into the valve body or atmosphere.
- Remote Operation: Capable of remote operation to ensure personnel safety.
- Maintenance: Designed for low maintenance, enabling uninterrupted operation between turnarounds. Incorporates a mechanical spreading mechanism for long-term sealing capability.
- Manual Operation: Manual operation is available for emergency use when needed.
Special Features :
- Dual independent discs for enhanced sealing.
- Active mechanical seating force for reliable shut-off.
- Corrosion and wear resistance for durability.
