Our dual ball valve represents a significant advancement in critical flow control technology, engineered specifically for the demanding requirements of the oil, gas, petrochemical, and refining industries. This robust dual ball valve features a unique trunnion-mounted, double-seal design within a three-piece body, providing superior performance and safety in high-pressure pipeline systems, making it an ideal choice for facilities in the Middle East and global markets.
The core design of this dual ball valve ensures maximum reliability. Its primary features include a double block and bleed (DBB) capability for safe isolation and cavity relief, essential for maintenance and safety protocols. The valve incorporates a fire-safe design certified to API 607, preventing catastrophic failure in emergency scenarios. Additional safety features like anti-blowout stems, an anti-static device, and a self-relieving cavity further enhance operational integrity. For environmental compliance, fugitive emission testing is available as an option. Constructed to API 6D standards, it guarantees durable service under extreme conditions.

A: This dual ball valve is designed and tested in accordance with API 607 fire-safe standards. Its special seat and seal materials provide a secondary metal-to-metal seal in the event of a fire, maintaining valve integrity and preventing fluid escalation.
A: The dual ball design allows each seat to independently block upstream and downstream pressure. The cavity between the seats can be safely depressurized (bled) through a dedicated port, verifying the seal integrity and enabling safe maintenance.
A: Yes, when specified with suitable materials like Duplex stainless steel or special alloys, this dual ball valve can be configured to handle sour (H2S) environments as per NACE MR0175/ISO 15156 requirements, common in Middle Eastern oil fields.
A: It ensures electrical continuity between the ball, stem, and valve body, preventing the buildup of static electricity caused by fluid flow, which is a critical safety feature in flammable hydrocarbon services.
