As a leading manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-performance, reliable fluid control solutions for demanding industrial applications. Our API 6D Fire Safe Ball Valve is engineered specifically for the critical tasks of marine fuel transfer and cargo handling, where safety, durability, and zero-leakage performance are non-negotiable. With years of expertise since our establishment in 2016 and a strong export presence across global markets from North America to Oceania, we understand the stringent requirements of offshore and marine operations. This valve is designed to offer superior shut-off capability and exceptional fire safety, ensuring the protection of valuable assets, personnel, and the environment in the event of an emergency. Trust our valves to deliver the performance and peace of mind your operations demand.
Our API 6D Fire Safe Ball Valve incorporates a host of advanced features and robust construction to meet the challenges of marine service:
- Certified Fire Safe Design: The valve is designed and tested in accordance with API 607, API 6FA, or similar fire-safe standards. It features a primary soft seal (like PTFE) for bubble-tight shut-off during normal operation and a secondary metal-to-metal seal that engages automatically in a fire scenario, preventing catastrophic fluid release.
- Robust Construction & Materials: We offer valve bodies in materials like WCB carbon steel, CF8/CF8M stainless steel, and duplex stainless steels to resist corrosion from seawater, fuels, and various chemicals. Critical internal components are selected for strength and wear resistance.
- Bubble-Tight Sealing: Utilizing advanced seat materials such as reinforced PTFE or PEEK, the valve ensures a reliable, long-lasting seal with extremely low torque operation, minimizing wear and extending service intervals.
- Anti-Static & Blowout-Proof Stem: The design includes an anti-static device to prevent spark generation from static electricity and a blowout-proof stem that retains the stem under pressure, enhancing operator safety.
- Versatile Actuation Options: The valve can be supplied with a manual handle (lever or gear-operated) or can be easily fitted with pneumatic or electric actuators for remote or automated process control, ideal for complex shipboard systems.
- Full Port or Reduced Port: Available in full bore (full port) design to minimize pressure drop and allow for pipeline pigging, or standard port for general applications where space and cost are considerations.

Frequently Asked Questions (FAQ)
Q1: What exactly does "Fire Safe" mean for this ball valve?
A1: A "Fire Safe" valve is designed to maintain a seal and prevent external leakage even when exposed to high temperatures from a fire. Our valve uses a primary soft seal for normal operation and a secondary metal seal that engages if the soft seal is compromised by heat, containing the fluid within the system as per API 607/6FA test protocols.
Q2: Can this valve be used for both fuel oil and liquefied cargo?
A2: Yes, it is suitable for a range of services including marine diesel oil (MDO), heavy fuel oil (HFO), and various liquid cargoes. The specific material selection (e.g., stainless steel for corrosion resistance) should be chosen based on the exact fluid properties. Consult our engineers for material compatibility guidance.
Q3: What documentation do you provide with the valves?
A3> We provide a comprehensive documentation package that typically includes Material Test Certificates (MTC), Certificate of Conformity (COC), pressure test reports, and a detailed dimensional drawing. Certifications for fire-safe testing can be supplied upon request.
Q4: Are your valves approved by major marine classification societies?
A4: While we hold ISO9001 certification, specific approvals from societies like ABS, DNV, or Lloyd's Register are generally obtained by the shipyard or end-user for the complete valve assembly as part of their system certification. We manufacture valves to the relevant standards these societies recognize (API, ASME) and can support the approval process with necessary documentation and witness testing.
Q5: What is the typical lead time for an order?
A5> Lead time depends on the valve size, material, pressure class, and quantity. For standard specifications from our inventory, it can be as short as 2-4 weeks. For large or custom-engineered orders, the lead time may extend to 8-12 weeks. We provide accurate lead time estimates with every quotation.
Q6: Do you offer actuated versions of this valve?
A6: Absolutely. We can supply the valve pre-assembled with pneumatic (double-acting or spring-return) or electric actuators, complete with mounting brackets and necessary controls. This provides a ready-to-install package for automated systems.
Q7: How do I determine the correct pressure class (e.g., Class 150 vs. Class 300) for my application?
A7: The pressure class must be selected based on the maximum working pressure and temperature of your system, following the ASME B16.34 pressure-temperature rating tables. Our technical team can assist you in selecting the appropriate class based on your provided operating conditions.
Q8: What after-sales support do you provide?
A8: We offer technical support for installation and operation, and can supply spare parts such as seats, seals, and stems. Our global market presence facilitates support for international projects.
