As a professional manufacturer with a strong foundation since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in delivering high-performance fluid control solutions for demanding maritime applications. Our Marine Ball Valve, engineered in strict compliance with the JIS F7300 standard and approved by leading classification societies like DNV and BV, is designed to meet the rigorous challenges of marine and offshore environments. We combine robust materials like carbon steel and cast iron with precision manufacturing to ensure reliable shut-off, long service life, and optimal safety for your piping systems. With an annual export value reflecting our global reach and commitment to quality, we are your trusted partner for critical marine components.

This valve is engineered for durability and performance in saltwater, fuel, and other shipboard fluid systems. Its design prioritizes ease of operation, maintenance, and safety under high-pressure conditions.

Robust Construction & Material Integrity: The primary body and ball are crafted from high-grade carbon steel or cast iron, selected for their excellent strength, corrosion resistance, and suitability for marine atmospheres. These materials ensure the valve withstands internal pressure, external environmental factors, and mechanical stress.
Stringent Standard Compliance: Manufactured to the JIS F7300 standard, this valve guarantees dimensional compatibility, pressure ratings (5K and 10K), and performance metrics specifically defined for marine use. This ensures seamless integration into shipbuilding and repair projects worldwide.
Third-Party Quality Assurance: The DNV and BV approvals serve as independent verification of the valve's design, material, and manufacturing quality. This certification is crucial for vessels and offshore installations requiring class approval, providing peace of mind and facilitating regulatory compliance.
Reliable Sealing and Operation: Features advanced seat and seal materials (options available upon request) that provide bubble-tight shut-off, even after prolonged cycles. The quarter-turn operation allows for quick and easy open/close control, which is vital in emergency or routine operations.
Versatile Application Scope: Suitable for a wide range of onboard services including:
- Ballast water systems
- Bilge and drain lines
- Fuel oil and lubricating oil transfer
- Cooling water circuits (sea water and fresh water)
- General service and utility lines

To provide a clear overview, here are some key specifications and potential configurations:

Parameter	Specification / Option
Design Standard	JIS F7300
Pressure Class	5K (Approx. 1.27 MPa) / 10K (Approx. 2.45 MPa)
Body Material	Carbon Steel (WCB) or Cast Iron (FC200/250)
Ball Material	Stainless Steel (304/316) or Chrome Plated Carbon Steel
Seat Material	PTFE, Reinforced PTFE, Nylon, Metal (customizable)
End Connection	Flanged (JIS B2220), Screwed (NPT, BSP), or Socket Weld
Operation	Lever Handle, Gear Operator, Pneumatic/Hydraulic Actuator (optional)
Temperature Range	-20°C to +200°C (dependent on seat material)

Benefits for Your Operations:

Enhanced System Reliability: Reduces the risk of leaks and failures in critical marine systems, minimizing downtime and maintenance costs.
Simplified Procurement & Compliance: The pre-obtained DNV/BV approvals streamline the approval process for your projects, saving valuable time and resources.
Global Supply Chain Support: With major shipment ports in Shanghai, Guangzhou, Hongkong, and Beijing, and a presence in markets across the Americas, Europe, Asia, Africa, and Oceania, we ensure timely and efficient delivery to shipyards and ports worldwide.
Cost-Effective Sourcing: As a direct manufacturer, we offer competitive pricing, especially for bulk orders starting from the MOQ of 20 units, providing significant value for fleet operators and shipbuilders.

Frequently Asked Questions (FAQ)

What does "5K" and "10K" pressure rating mean in the JIS F7300 standard?
In the JIS F7300 standard, "K" stands for "Kilo" and represents a pressure class. 5K corresponds to a nominal pressure of approximately 1.27 MPa (184 psi), and 10K corresponds to approximately 2.45 MPa (355 psi) at ambient temperature. It indicates the maximum allowable pressure the valve is designed to withstand.
Why is DNV/BV approval important for this marine ball valve?
DNV (Det Norske Veritas) and BV (Bureau Veritas) are leading international classification societies. Their approval certifies that the valve's design, materials, and manufacturing process meet specific safety, quality, and performance standards required for marine and offshore applications. This approval is often mandatory for equipment installed on classed vessels and offshore platforms.
Can I order a smaller quantity than the stated MOQ of 20 units?
The Minimum Order Quantity (MOQ) of 20 units is set for standard configurations to optimize production and logistics. For non-standard specifications, prototype orders, or established long-term partnership discussions, we may consider smaller quantities. Please inquire directly with our sales team to explore available options.
What are the available end connection types for this valve?
This valve series is typically offered with flanged ends conforming to JIS B2220 standard dimensions, which is common for marine piping. However, other end connections such as NPT/BSP threaded ends or socket weld ends are often available as customizable options to suit your specific piping design requirements.
How does the carbon steel version compare to the cast iron version for marine use?
Carbon steel (e.g., WCB) generally offers higher tensile strength and better impact resistance than cast iron, making it suitable for more demanding services and higher-pressure applications. Cast iron (e.g., FC200) provides good corrosion resistance and is a cost-effective option for lower-pressure general service lines. The choice depends on the specific fluid, pressure, and mechanical requirements of your application.
Are actuators available for automated operation?
Yes, automation is a common requirement. We can provide this valve prepared for the installation of pneumatic (air-operated) or hydraulic actuators. The valve can be supplied as a manual unit (lever handle) or configured as a complete actuated package. Actuator selection (brand, type, fail-safe mode) is customizable based on your control system specifications.
What is the typical lead time for an order of 100 units?
Lead time varies based on order size, specification complexity, and current production schedule. For a standard order of 100 units, the typical production lead time might range from 4 to 6 weeks. We provide a confirmed lead time with every formal quotation to help you plan your project schedule effectively.
Do you provide documentation like material certificates and test reports?
Absolutely. As part of our quality assurance and to support your classification needs, we provide essential documentation including Material Test Certificates (MTC/MTR), pressure test reports (hydrostatic and pneumatic), and certificates of conformity. For DNV/BV approved valves, the relevant approval certificates are also supplied.
