As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance marine valves that meet stringent industry demands. Our CB/T3191 Marine Ball Valve with Reduced Bore is engineered specifically for shipbuilding and offshore applications, offering reliable shut-off and control in critical marine piping systems. With years of experience since our establishment in 2016 and a significant annual export value, we understand the need for durable, corrosion-resistant valves that perform under harsh sea conditions. This valve is designed to comply with shipbuilding standards, ensuring safety, longevity, and ease of maintenance for vessel operators worldwide.
This marine ball valve features a robust construction and several key advantages for maritime use:
- Reduced Bore Design: The bore diameter is smaller than the pipeline, which reduces weight and cost while maintaining sufficient flow for many marine applications. This design is ideal for systems where full port flow is not critical.
- Corrosion Resistance: Manufactured from materials like carbon steel with protective coatings or stainless steel, the valve withstands exposure to seawater, salt spray, and marine atmospheres.
- Bubble-Tight Sealing: Utilizing advanced seat materials such as PTFE or reinforced polymers, the valve ensures leak-proof operation, crucial for preventing environmental contamination and system failures.
- Easy Operation & Maintenance: Designed for quick quarter-turn operation, the valve can be equipped with a manual lever, gear operator, or automated actuator for remote control. Its simple structure allows for easy inline maintenance.
- Fire Safe Option: Available with fire-safe design features that prevent leakage in case of fire, meeting additional safety requirements for fuel and oil lines.
- Versatile Applications: Suitable for a wide range of services on ships and offshore platforms, including ballast systems, bilge lines, fuel transfer, cooling water, compressed air, and general service lines.

Frequently Asked Questions (FAQ)
-
What does "CB/T3191" standard mean for this valve?
CB/T3191 is a Chinese shipbuilding standard that specifies the technical requirements for marine flanged steel ball valves. Valves manufactured to this standard are designed and tested to meet the specific demands of marine environments, including materials, pressure ratings, dimensions, and testing procedures suitable for shipboard use. -
What is the main advantage of a reduced bore ball valve compared to a full bore one?
A reduced bore (or regular port) valve has a smaller flow path than the connecting pipe. The primary advantages are a lower weight, more compact structure, and often a lower cost. It is suitable for applications where a slight pressure drop is acceptable and where saving space and weight on a vessel is important. -
Can this valve be used for both seawater and fuel oil lines?
Yes, provided the correct material selection is made. For seawater service, materials like stainless steel (CF8M/316) or duplex stainless steel with appropriate coatings are recommended. For fuel oil, carbon steel with suitable seals (often PTFE) is common. It is crucial to specify the medium when ordering to ensure compatibility. -
What types of actuators can be fitted to this valve?
The valve can be fitted with manual levers, manual gearboxes for high-torque applications, pneumatic actuators (double-acting or spring-return), or electric actuators. The choice depends on the required mode of operation (on/off or modulating), available power source, and automation level of the system. -
Is this valve fire-safe certified?
A standard fire-safe design is optional. We can provide valves that meet common fire-safe test standards (like API 607, API 6FA, ISO 10497) upon request. Please specify this requirement in your inquiry. -
What is the typical delivery time for an order?
Delivery time varies based on order quantity, specification complexity, and material availability. Standard specifications typically have shorter lead times. We work closely with clients to provide accurate schedules and can leverage our multiple shipment ports for efficient logistics. -
Do you provide documentation and certification with the valves?
Yes, we provide essential documentation including material certificates, test reports (like pressure test), and a certificate of conformity. For specific project requirements, additional documentation can be discussed and provided. -
Can you customize valves outside the standard size and pressure ratings?
Yes, as a manufacturer, we have the capability to customize valves. This includes special sizes, pressure classes, materials, coatings, and end connections. Customization may affect lead time and cost, which we can clarify during the quotation process.
