NSV has successfully completed the production and shipment of a batch of 12in Electric DBB Double-Ball Valves.

These valves feature a DBB (Double Block and Bleed) configuration integrated with a double-ball design. Housing two independent ball elements, the valve creates distinct upstream and downstream sealing barriers. This dual-sphere architecture ensures true double isolation while effectively distributing pressure loads, significantly enhancing sealing stability and service life under high-pressure conditions.

Manufactured in strict compliance with API 6D, the double-ball structure guarantees complete media isolation. An integrated cavity relief mechanism automatically vents abnormal pressure caused by thermal expansion, ensuring safety during online maintenance. Equipped with high-performance electric actuators, the valves support remote operation and Emergency Shutdown (ESD), allowing seamless integration into DCS/PLC systems.

Thank to our client for their confidence in NSV engineering solution. We remain committed to rigorous craftsmanship to ensure the safe operation of the project site.
