As a professional valve manufacturer with a strong commitment to quality, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance API 6D Marine Ball Valve. Engineered specifically for the demanding environments of offshore oil and gas pipelines, this valve is designed to provide reliable and secure shutoff, ensuring operational safety and integrity. With our ISO9001 certified manufacturing processes and years of expertise since 2016, we deliver valves that meet the stringent requirements of global energy infrastructure. Our product is a trusted solution for critical applications where failure is not an option.

Our API 6D Marine Ball Valve is built to withstand the harsh conditions of offshore platforms and subsea pipelines. It combines robust construction with advanced sealing technology to deliver exceptional performance.

Key Features and Technical Advantages:

Full Compliance with API Standards: Manufactured in strict adherence to API 6D specification for pipeline valves and API 607/6FA for fire-safe design, ensuring global acceptance and reliability.
Superior Material Selection: Available in a range of materials including carbon steel, stainless steel (CF8M, CF3M), and duplex/super duplex steels (F51, F53) to combat corrosion from seawater, H2S, and CO2.
Robust Pressure & Temperature Rating: Designed for high-pressure applications with pressure classes from Class 150 to Class 2500, capable of handling extreme temperatures from cryogenic to elevated levels.
Advanced Sealing System: Features a unique seat design with secondary sealing injection ports. The primary seals are often PTFE or reinforced PTFE, while metal-seated versions are available for high-temperature or abrasive service.
Anti-Static & Fire-Safe Design: Incorporates an anti-static device to prevent sparking and meets API 607 fire test standards, ensuring safe operation even in fire scenarios.
Blow-Proof Stem Design: The stem is securely retained under pressure, preventing accidental ejection and enhancing personnel safety.
Low Torque Operation: Precision-machined ball and seats ensure smooth, low-torque operation, extending the life of actuators and reducing operational effort.
Versatile End Connections: Supplied with flanged ends (RF, RTJ), butt weld, or socket weld ends to seamlessly integrate into existing pipeline systems.

Frequently Asked Questions (FAQ):

Q: What is the primary advantage of an API 6D ball valve over a standard ball valve for offshore use?
A: API 6D valves are specifically designed for pipeline applications with stricter requirements on design, pressure containment, face-to-face dimensions, and testing. They offer enhanced safety features like fire-safe design and anti-static devices, which are critical for offshore oil and gas environments.
Q: Can this valve be used for subsea applications?
A: While this valve is engineered for harsh offshore conditions, subsea service requires specific design adaptations like ROV interfaces and deeper pressure ratings. We offer specialized subsea ball valves; please inquire for details on subsea configurations.
Q: What material options are recommended for seawater service?
A: For seawater applications, we typically recommend duplex stainless steel (UNS S31803/S32205) or super duplex stainless steel (UNS S32750) due to their excellent resistance to chloride-induced corrosion and high strength.
Q: Do you provide actuated versions, and what are the control options?
A: Yes, we can supply the valve with pneumatic (double-acting or spring-return), electric, or hydraulic actuators. Control options include limit switches, positioners, solenoid valves, and can be integrated into your SCADA system.
Q: What is the typical delivery time for a custom-sized valve, such as 24" Class 1500?
A: Delivery time depends on material availability and actuator sourcing. For standard materials, lead time for large, high-pressure valves can range from 12 to 20 weeks. We provide accurate schedules upon receipt of detailed specifications.
Q: How do you ensure the valve's sealing performance over its lifespan?
A: Our valves feature a secondary sealant injection system. If the primary seal shows signs of wear, a sealant can be injected under pressure to restore the seal without taking the valve out of service, greatly extending maintenance intervals.
Q: Are your valves suitable for sour service (H2S environments)?
A: Yes, we offer valves with materials compliant with NACE MR0175/ISO 15156 standards for sour service. Specific material grades and hardness controls are applied to prevent sulfide stress cracking.
Q: What documentation accompanies the valves upon delivery?
A: Each valve is supplied with a comprehensive documentation package, including Material Test Certificates (MTC), Factory Test Reports (per API 598), Certificate of Conformance, Pressure Test Charts, and detailed Installation & Maintenance Manuals.
