As a leading manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our premium Full Bore Marine Ball Valve. Engineered to meet the rigorous JIS F7300 standard, this valve is specifically designed for demanding marine and offshore applications. With over seven years of expertise since our establishment in 2016 and an annual export value exceeding US$1 million, we understand the critical need for reliability and safety in shipboard systems. Our valve ensures unimpeded fluid flow, robust construction, and comes complete with a detailed installation guide and a comprehensive spare parts kit, providing exceptional value and peace of mind for shipbuilders, repair yards, and marine engineers worldwide.
This valve is engineered for superior performance in saltwater, fuel, and other marine service media. Its full bore design minimizes pressure drop, allowing for efficient pumping and reducing operational costs. The valve body is constructed from high-grade materials such as bronze, stainless steel (CF8/CF8M), or cast steel (WCB/WCC), selected for excellent corrosion resistance and mechanical strength. The precision-machined ball and stem ensure smooth, bubble-tight shut-off, critical for safety and environmental protection.
Key Features & Technical Advantages:
- JIS F7300 Compliance: Manufactured in strict accordance with the Japanese Industrial Standard for marine valves, guaranteeing suitability for ship machinery and piping systems.
- Full Port Design: Provides a flow path with minimal restriction, equivalent to the pipeline's inner diameter, reducing turbulence and pressure loss.
- Enhanced Durability: Features chrome-plated or stainless steel balls and PTFE or reinforced seats for long service life and reliable sealing against high pressures.
- Versatile Actuation: Available with manual lever, gear operator, or automated actuators (pneumatic/electric) for remote or automated control systems.
- Complete Package: Each valve is supplied with a user-friendly installation guide and a spare parts kit containing essential seals and gaskets, minimizing downtime for maintenance.

Frequently Asked Questions (FAQ)
Q1: What is the significance of JIS F7300 compliance for this valve?
A1: JIS F7300 is a Japanese Industrial Standard specifically for marine steel valves. Compliance ensures the valve's design, materials, manufacturing, and testing are suitable for the harsh conditions of marine service, including vibration, corrosion, and pressure demands, often meeting the requirements of major marine classification societies.
Q2: Does the "full bore" design affect the valve's pressure rating?
A2: No, the full bore design refers to the internal port size matching the pipeline ID. Our valves are engineered to maintain their stated pressure ratings (e.g., Class 150, 300) regardless of port type. The robust construction of the body and ball ensures integrity under rated pressure.
Q3: What is typically included in the spare parts kit?
A3: The kit commonly includes critical wear components such as stem seals (O-rings), body seat rings, and gaskets. The exact contents may vary by valve size and material; a detailed list is provided with the installation guide.
Q4: Can this valve be used for both freshwater and seawater applications?
A4: Yes, but material selection is key. For seawater, we highly recommend stainless steel (CF8M/316) or bronze bodies for superior corrosion resistance. Cast steel valves with appropriate coatings can also be specified.
Q5: Are automated actuation options available?
A5: Absolutely. The valve can be fitted with pneumatic (double-acting or spring-return) or electric actuators. Please specify your required torque, voltage, and control signal when inquiring.
Q6: What is the lead time for orders?
A6: Standard sizes and materials typically have shorter lead times. For large or customized orders, we provide a production schedule upon receipt of your detailed specifications. Our multiple shipping ports help expedite delivery.
Q7: Is the valve tested before shipment?
A7: Yes. Every valve undergoes rigorous factory testing, which includes shell tests, seat leakage tests (typically per API 598 or equivalent), and operational checks to ensure proper function.
Q8: Do you provide documentation for classification society approval?
A8> We can provide standard material certificates and test reports. For specific classification society (e.g., ABS, DNV, LR) certification, please advise during the inquiry stage as it may involve additional procedures and documentation.
