As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-integrity fluid control solutions for demanding global industries. Our Fire Safe API 6D Marine Ball Valve for Offshore Service is engineered to meet the rigorous safety and performance standards required in offshore oil & gas platforms, FPSOs, and marine applications. With an annual export value of US$1-1.5 million and a strong presence across continents from North America to Southeast Asia, we understand the critical need for reliability under extreme conditions. This valve is not just a component; it's a safeguard, designed to maintain sealing integrity during and after exposure to fire, ensuring operational continuity and protecting valuable assets and personnel.
This valve is meticulously manufactured to comply with API 6D specifications for pipeline valves and incorporates fire-safe design per API 607/API 6FA standards. The core value lies in its dual-sealing system: under normal operation, the primary soft seat (like PTFE) ensures bubble-tight shut-off. In a fire event, the soft seat degrades, but the secondary metal-to-metal seat engages, providing a critical seal to prevent catastrophic fluid release. This fail-safe mechanism is paramount for offshore environments where safety is non-negotiable.
Key Features & Technical Advantages:
- Superior Fire Safety: Tested to withstand intense heat and maintain sealing performance as per API fire-safe standards, a mandatory requirement for offshore and hydrocarbon service.
- Robust Construction: Available in a range of durable materials including Carbon Steel (WCB, LCB), Stainless Steel (CF8M, CF3M), and Duplex Steel to resist corrosion from seawater and process fluids.
- Full Compliance Documentation: Each valve is supplied with a comprehensive Mill Test Report (MTR), providing traceability for material chemistry and mechanical properties, which is essential for project documentation and quality audits.
- Versatile Configuration: Designed for various offshore services including crude oil, produced water, fuel gas, and chemical injection lines. Configurations include standard port, full port, and can be equipped with anti-static devices, blowout-proof stems, and locking devices.
- Multiple Actuation Options: To suit different automation needs on offshore platforms, the valve can be fitted with manual levers or gearboxes, pneumatic actuators, or electric actuators.

Frequently Asked Questions (FAQ):
-
Q: What exactly does "Fire Safe" mean for this ball valve?
A: "Fire Safe" means the valve is designed and tested to maintain a seal (internal and external leakage control) during and after exposure to a specified fire condition, as per standards like API 607. It features a secondary metal seat that engages if the primary soft seal is compromised by heat. -
Q: Is the Mill Test Report (MTR) included with every valve?
A: Yes, a comprehensive Mill Test Report is provided as standard for each valve. It details the chemical composition and mechanical properties of the materials used, ensuring full traceability and compliance with project specifications. -
Q: Can this valve be used in subsea applications?
A: This standard model is designed for offshore topside service. For subsea applications, specific design modifications regarding pressure ratings, materials, and sealing are required. Please consult our engineering team for subsea valve solutions. -
Q: What are the available actuation methods?
A: The valve can be supplied as a manual unit (lever or gear operated) or automated with pneumatic (double-acting or spring-return) or electric actuators. The choice depends on your control system and power availability on the platform. -
Q: How do I select the correct pressure class and material for my service?
A: Selection depends on the operating pressure, temperature, and fluid media (e.g., seawater, crude oil, chemicals). Our technical team can assist you based on your P&ID and process data to recommend the optimal Class (e.g., 300, 600) and material (e.g., WCB, CF8M, Duplex). -
Q: Are spare parts readily available?
A: Yes, as the manufacturer, we maintain an inventory of critical spare parts like seats, seals, and stems. We recommend purchasing a spare parts kit with your valve order for critical services to minimize future downtime. -
Q: What is the typical lead time for an order?
A: Lead time varies based on size, material, and quantity. Standard configurations typically have a shorter lead time. We provide accurate delivery schedules upon receipt of your detailed inquiry. -
Q: Do you offer third-party inspection and certification services?
A: Yes, we can arrange and facilitate third-party inspection (e.g., DNV, ABS, Lloyd's) as per client requirements. All costs for such services are typically borne by the buyer and are available upon request.
