As a specialized manufacturer with a strong focus on marine and offshore applications, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our FPSO Marine Ball Valve manufactured in strict compliance with the CB/T3191 standard. Engineered for the demanding conditions of Floating Production Storage and Offloading (FPSO) vessels and other marine systems, this valve is built to deliver exceptional reliability, long service life, and minimal maintenance. We understand that downtime in offshore operations is costly, which is why we back our product with an extended warranty on the body and seat and provide comprehensive technical support. Trust our decade of manufacturing expertise and commitment to quality, certified under ISO9001, to meet your critical flow control needs.
Our FPSO Marine Ball Valve is designed to handle a wide range of media, including seawater, crude oil, hydrocarbons, and various process fluids. Its robust construction ensures performance under high pressure, corrosive environments, and constant motion typical of offshore platforms.
- Superior Sealing Performance: The precision-machined ball and advanced seat materials (like PTFE or metal) create a bubble-tight seal, preventing leaks that could lead to safety hazards or environmental contamination.
- Extended Durability: The valve body is constructed from high-grade materials such as carbon steel (WCB), stainless steel (CF8/CF8M), or duplex stainless steel, offering excellent resistance to corrosion and erosion.
- Low Maintenance Design: Featuring a simple quarter-turn operation and a streamlined flow path, the valve minimizes pressure drop and requires less frequent servicing compared to other valve types.
- Versatile Actuation Options: Available with manual lever handles, gear operators, or automated actuators (pneumatic/electric) for remote operation and integration into control systems.
- Enhanced Safety: The design includes features like a blow-out proof stem and fire-safe construction (optional) to meet stringent offshore safety standards.

Frequently Asked Questions (FAQ)
Q1: What does the CB/T3191 standard entail for this ball valve?
A1: CB/T3191 is a Chinese national standard specifically for ship valves. It defines requirements for design, materials, manufacturing, testing, and inspection to ensure the valve's suitability and safety for marine applications, including pressure ratings, corrosion resistance, and marking.
Q2: What exactly is covered under the "Extended Warranty on Body and Seat"?
A2: This warranty extends the standard coverage period specifically for the valve body casting/forging and the seat rings against defects in material and workmanship under normal service conditions. The exact duration and terms will be specified in the sales contract.
Q3: Are these valves suitable for sour service (H2S environments)?
A3: Yes, we can supply valves configured for sour service. This typically involves using NACE MR0175/ISO 15156 compliant materials (e.g., certain grades of stainless or duplex steel) and special manufacturing controls. Please specify this requirement during inquiry.
Q4: Can you provide valves with actuators for automated control?
A4: Absolutely. We offer a full range of actuation solutions, including pneumatic (double-acting or spring-return), electric, and hydraulic actuators. We can pre-assemble and test the valve-actuator package before shipment.
Q5: What kind of technical support do you provide?
A5: Our technical support includes assistance with valve selection based on your service conditions, installation and maintenance documentation, guidance on spare parts, and remote troubleshooting advice. For critical issues, on-site service can be arranged.
Q6: What certifications do your valves carry besides ISO9001?
A6: While ISO9001 certifies our quality management system, the valves themselves can be manufactured and tested to meet various standards such as API 607/6FA (fire-safe), API 6D, and can carry CE marking (PED) upon request. Specific certifications depend on the order requirements.
Q7: What is your typical lead time for an order?
A7: Lead time varies based on order quantity, size, material, and configuration. For standard specifications, it typically ranges from 4 to 8 weeks. We provide a confirmed schedule upon order placement.
Q8: Do you offer customization for non-standard sizes or pressures?
A8: Yes, as a manufacturer, we have the engineering capability to customize valves for special sizes, pressure classes, materials, or design features to meet unique project specifications. Please share your detailed requirements for evaluation.
