As a leading manufacturer with ISO 9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-performance, custom-engineered marine ball valve solutions. Since our establishment in 2016, we have focused on the demanding requirements of shipboard fuel oil and lube systems, understanding that reliability and safety are non-negotiable in maritime operations. Our valves are designed to withstand harsh marine environments, offering superior sealing, durability, and ease of operation. With an annual export value reaching US$1.5 million, our products are trusted by shipyards and vessel operators across North America, South America, Europe, Asia, and beyond, shipped efficiently from major ports like Shanghai and Hong Kong.
Our custom marine ball valves are engineered for critical service in fuel and lubrication lines. We offer a comprehensive range of configurations to meet specific system pressures, fluid compatibilities, and space constraints onboard various vessels.
- Robust Construction & Material Selection: We utilize premium materials such as carbon steel (WCB), stainless steel (CF8M, 316), and duplex steel to combat corrosion from seawater and aggressive media. Valve bodies are precision-cast and machined to ensure dimensional accuracy and structural integrity.
- Superior Sealing Performance: The heart of our valve is its sealing system. We offer multiple seat options, including standard PTFE for general service, reinforced PTFE for enhanced durability, and metal seats for high-temperature or abrasive applications. This ensures bubble-tight shut-off and long service life, preventing costly leaks in fuel and lube systems.
- Flexible Actuation & Control: Valves can be supplied with manual levers or gearboxes. For remote or automated control, we integrate with pneumatic, electric, or hydraulic actuators from reputable brands, providing smooth and reliable operation as part of your vessel's control system.
- Fire-Safe & Anti-Static Design: Critical for fuel handling, our valves can be manufactured to meet fire-safe standards (API 607/6FA). This design includes secondary metal seals that engage in a fire event, preventing catastrophic failure. Anti-static devices are also incorporated to safely dissipate static electricity.
- Customization for Exact Fit: We excel at customization. Whether you need specific face-to-face dimensions, special flange standards (ISO, DIN, JIS, ANSI), locking devices, drain/vent ports, or extended stems for insulated lines, our engineering team works with you to deliver a perfect fit for your application.

Frequently Asked Questions (FAQ)
Q1: What makes a marine ball valve different from a standard industrial ball valve?
A: Marine ball valves are specifically designed for the harsh conditions at sea, including resistance to saltwater corrosion, vibration, and potential fire hazards. They often feature materials like bronze or specific stainless-steel grades, fire-safe designs, and certifications from maritime authorities. Standard industrial valves may not meet these rigorous demands.
Q2: Can you provide valves with specific certifications like ABS, DNV, or LR?
A: Yes, we regularly manufacture valves for classification society approval. While standard production follows ISO/API standards, we can arrange for third-party inspection and certification by ABS, DNV, LR, BV, or others as required by your project. Please specify this need during inquiry.
Q3: How do I determine the right material for my fuel oil or lube oil application?
A: Material selection depends on the fluid's properties (viscosity, additives), temperature, pressure, and environmental exposure. Carbon steel is common for fuel oil, while stainless steel (316/316L) is preferred for lube oil and more corrosive environments. Our engineers can provide recommendations based on your detailed service conditions.
Q4: What is the typical lead time for a custom marine ball valve order?
A: Lead time varies based on the complexity of customization, order quantity, and material availability. For standard customized designs, it typically ranges from 4 to 8 weeks. We provide a firm schedule upon order confirmation and keep clients updated on progress.
Q5: Do you offer actuated valve packages?
A: Absolutely. We can supply complete actuated packages, integrating ball valves with pneumatic, electric, or hydraulic actuators, limit switches, solenoid valves, and positioners. We source actuators from trusted partners or can work with your preferred brand to ensure system compatibility.
Q6: What kind of testing do your valves undergo before shipment?
A: Every valve undergoes rigorous testing, which typically includes a shell test (body strength), seat leak test (sealing performance), and operational test. For critical applications, we can perform additional tests like fire testing, low-temperature testing, or NDE (Non-Destructive Examination) as specified. Test reports are available.
Q7: Can you manufacture valves to match existing flange standards or dimensions on our ship?
A: Yes, this is a core part of our customization service. We can manufacture valves to match virtually any international (ISO, DIN, ANSI) or specific national flange standard. Providing drawings or samples of your existing piping connection ensures a perfect fit.
Q8: What is your warranty policy?
A: We offer a standard warranty against manufacturing defects for a period of 12 months from the date of shipment, under normal service conditions as specified. The warranty covers repair or replacement of defective parts. Specific terms are detailed in our commercial contract.
