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 BENEFITS:

Dual independent discs for enhanced sealing.
Active mechanical seating force for reliable shut-off.
Corrosion and wear resistance for durability.
Prevents deposits and minimizes purge steam consumption.
Easy maintenance with automated locking and no need for cooling water.
Throttling capability for efficient control.
