As a leading valve manufacturer with a strong global presence, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our specialized Full Bore Marine Ball Valve. Engineered specifically for the demanding environments of offshore platforms, this valve is designed to provide reliable, low-pressure-drop fluid control for critical systems. With our commitment to quality certified by ISO9001 and an annual export value exceeding US$1 million, we deliver robust solutions trusted by clients across North America, Southeast Asia, Europe, and beyond. Our valve ensures maximum flow efficiency and dependable shut-off, making it an essential component for safe and efficient offshore operations.
Our Full Bore Marine Ball Valve is built to withstand the harsh conditions of marine and offshore applications. The full port design offers a flow path with minimal restriction, which is crucial for systems requiring high flow rates or handling viscous fluids. This feature significantly reduces pressure drop across the valve, leading to energy savings and reduced pump strain. The valve body is constructed from premium materials such as carbon steel, stainless steel, or duplex steel, selected for their excellent corrosion resistance against seawater and process fluids. A robust sealing system, often utilizing PTFE or reinforced seats, ensures a bubble-tight seal and long service life even under high-pressure cycling.
- Superior Flow Capacity: The full bore design provides a flow area equal to the pipeline, minimizing turbulence and pressure loss for optimal system efficiency.
- Exceptional Durability: Manufactured from corrosion-resistant alloys with protective coatings, the valve offers extended service life in saline and chemically aggressive offshore environments.
- Reliable Sealing Performance: Advanced seat materials and precision machining ensure zero leakage, meeting stringent industry standards for safety and environmental protection.
- Versatile Actuation Options: Available with manual lever, gear operator, or automated actuators (pneumatic/electric) for remote or automated control within platform systems.
- Easy Maintenance & Operation: The trunnion-mounted or floating ball design, along with a blow-out-proof stem, allows for easy in-line maintenance and safe operation under high pressure.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of a full bore ball valve over a standard port valve for offshore use?
A: The primary advantage is minimal flow restriction. A full bore valve has an internal diameter matching the pipeline, which reduces pressure drop, increases flow capacity, and allows for easier pigging or cleaning of the line—a critical feature for many offshore fluid systems. -
Q: Are these valves suitable for sour service (H2S environments)?
A: Yes, we offer valves constructed from materials compliant with NACE MR0175/ISO 15156 standards for sour service. This can be specified upon request to ensure integrity in environments containing hydrogen sulfide. -
Q: What actuation methods are available, and can they be integrated into a platform's control system?
A: We provide manual (lever or gear), pneumatic, and electric actuation options. Our automated actuators can be equipped with positioners, limit switches, and various communication protocols (e.g., 4-20mA) for seamless integration into your platform's Distributed Control System (DCS). -
Q: Do you offer fire-safe certified versions?
A: Fire-safe design is a common requirement. Our valves can be manufactured to meet API 607, API 6FA, or ISO 10497 fire test standards. Please specify this requirement when inquiring. -
Q: What is the typical delivery lead time for these valves?
A: Lead time varies based on size, material, and actuation specifications. For standard configurations, it typically ranges from 4 to 8 weeks. We provide accurate timelines upon receipt of your detailed specifications. -
Q: Can you provide custom coatings or cathodic protection for enhanced corrosion resistance?
A: Absolutely. We offer various external coatings like epoxy, FBE, or galvanizing. Additionally, valves can be fitted with sacrificial anode kits or insulating kits for Cathodic Protection systems as required by your project specifications. -
Q: How do you ensure quality control during manufacturing?
A: Our ISO9001 quality management system governs every stage, from material sourcing to final testing. Each valve undergoes rigorous tests, including hydrostatic shell/seat tests, high-pressure gas tests (if applicable), and material verification, with full documentation provided. -
Q: What after-sales support do you provide?
A: We offer comprehensive technical documentation, installation guidance, and spare parts support. Our team is available to assist with troubleshooting and can provide maintenance recommendations to extend valve service life.
