Product Description
Double block and bleed (DBB) isthe practice of shutting in a section of pipe on both sides of the valve rather than just one. It means you close the ball valves to block both the upstream and downstream sides of your working area, and then bleed any pressure that remains in the piping and valve
API 6Ddefines a double block and bleed valve as a single valve with two seating surfaces that, in the closed position, provides a seal against pressure from both ends of the valve with a means of vending/bleeding the cavity between the seating surfaces

Distributors, wholesalers, and retailers offer these valves with comprehensive support and after-sales service, ensuring seamless integration into your industrial setup.
FAQs of Double Block Bleed Valve:
Q: How does a Double Block Bleed Valve function in high-pressure industrial water systems?
A: This valve uses two isolation barriers and a bleed mechanism to provide complete shut-off and isolation of water. In high-pressure environments, it enables safe maintenance and inspection by preventing leakage and cross-contamination.
Q: What are the benefits of choosing a yellow Double Block Bleed Valve for industrial usage?
A: The yellow color enhances visibility for safety purposes, while high-pressure capability and manual operation ensure reliable performance, reduced downtime, and easier maintenance in critical industrial water systems.
Q: When should a Double Block Bleed Valve be installed in a water pipeline?
A: Install these valves whenever you require enhanced safety, maintenance access, or the need to completely isolate sections of a high-pressure water pipeline, especially in hazardous or critical industrial environments.
Q: Where can I find Double Block Bleed Valves in India?
A: These valves are widely available through reputable dealers, distributors, exporters, manufacturers, suppliers, and wholesalers across major industrial hubs and cities throughout India.
Q: What is the process for procuring and installing a Double Block Bleed Valve?
A: To procure, contact a trusted manufacturer or supplier in India. After purchase, professional installation according to manufacturer guidelines ensures optimal operation and longevity. Regular inspection and maintenance are recommended.
Q: How is the manual operation advantageous for industrial valves?
A: Manual operation allows precise control, quick intervention during emergencies, and straightforward maintenance, making it ideal for plant personnel handling high-pressure water applications.
