As a professional manufacturer specializing in industrial valves, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our Marine Grade Bronze Ball Valve, engineered to meet the rigorous JIS F7300 standard for marine applications. With years of expertise since our establishment in 2016, we understand the critical demands of ship piping systems, where reliability and corrosion resistance are non-negotiable. This valve is designed to provide a leak-proof, durable, and low-maintenance solution for controlling fluid flow in seawater, bilge, ballast, and other essential marine services. Our commitment to quality, backed by ISO9001 certification, ensures that every valve delivers consistent performance, helping shipbuilders and marine engineers enhance the safety and efficiency of their vessels.
This valve stands out due to its robust construction and specialized design tailored for the harsh marine environment. Below are the key features and technical specifications that define its superior performance:
- Superior Corrosion Resistance: Manufactured from high-grade marine bronze alloys (such as C83600 or C84400), the valve body and components offer exceptional resistance to seawater, salt spray, and other corrosive elements commonly found in marine operations.
- JIS F7300 Compliance: Adherence to the Japanese Industrial Standard F7300 guarantees that the valve meets stringent requirements for materials, dimensions, pressure ratings, and testing specific to shipbuilding and marine equipment.
- Flanged End Connection: The flanged ends, typically conforming to JIS 10K or 16K pressure ratings, ensure a secure, bolt-on connection to piping systems, facilitating easy installation, maintenance, and a reliable seal under high-pressure conditions.
- Full Port Design: Provides minimal flow restriction, reducing pressure drop and allowing for efficient fluid passage, which is crucial for maintaining system performance in critical marine applications.
- Durable Sealing Mechanism: Equipped with PTFE or reinforced PTFE seats, the valve ensures a tight seal, excellent chemical resistance, and long service life even with frequent cycling.
- Versatile Operation: Standard lever operation allows for quick quarter-turn on/off control. For larger sizes or automated systems, a gearbox operator or pneumatic/electric actuation is available upon request.
The technical specifications are detailed in the table below to provide a clear overview of the valve's capabilities:
| Attribute | Specification |
| Design Standard | JIS F7300 |
| Pressure Rating | PN16 / JIS 10K (Higher ratings like 16K customizable) |
| Temperature Range | -20°C to 200°C |
| Port Type | Full Port |
| Seat Material | PTFE / Reinforced PTFE (Other materials optional) |
| Operation | Lever (Gearbox, Pneumatic, Electric Actuators optional) |
| End Connection Standard | JIS B2210/B2220 Flange (10K, 16K) |
| Size Range (Nominal) | DN15 (1/2") to DN200 (8") (Other sizes available upon request) |
Choosing our Marine Grade Bronze Ball Valve brings significant advantages to your marine projects:
- Enhanced System Reliability: The robust construction and corrosion-resistant materials minimize the risk of failure, ensuring uninterrupted operation of vital ship systems.
- Reduced Maintenance Costs: The durable design and high-quality seals extend service intervals, lowering the total cost of ownership over the valve's lifespan.
- Global Compliance: Compliance with JIS F7300 makes the valve suitable for international shipbuilding projects, particularly in markets across Asia, where this standard is widely recognized.
- Ease of Integration: The standardized flanged connection simplifies installation and replacement within existing JIS-compliant piping networks, saving time and labor.
- Operational Safety: A reliable shut-off capability is crucial for controlling hazardous fluids on board; this valve provides secure, bubble-tight sealing to enhance overall vessel safety.

Frequently Asked Questions (FAQ)
Q1: What makes "marine grade" bronze different from standard bronze?
A1: Marine grade bronze refers to specific copper alloy compositions, such as C83600 (85-5-5-5) or C84400, which are formulated with higher tin and other alloying elements. These alloys offer superior resistance to dezincification and corrosion in seawater compared to standard bronze, making them essential for prolonged exposure to marine environments.
Q2: Can this JIS F7300 valve be used with ANSI or DIN flange standards?
A2: The valve is manufactured with JIS standard flanges (e.g., JIS 10K). While the bolt hole patterns and dimensions differ from ANSI or DIN, adaptor flanges or custom machining can be provided upon request to facilitate connection to other piping standards. It is recommended to specify your flange requirements when ordering.
Q3: What types of fluids is this valve suitable for in a ship?
A3: This valve is designed for a wide range of shipboard fluids, including seawater (for cooling, firefighting, or ballast), bilge water, oily water, compressed air, and non-aggressive chemicals. The PTFE seats provide compatibility with many media, but suitability for specific aggressive chemicals should be verified.
Q4: Is the valve suitable for high-pressure applications?
A4: The standard pressure rating is PN16 / JIS 10K, which is suitable for many marine piping applications. For higher pressure requirements (e.g., JIS 16K or PN25), valves can be designed and manufactured with reinforced bodies and appropriate testing. Please provide your operating pressure details for a customized solution.
Q5: What are the available actuation options?
A5: The valve is typically supplied with a manual lever for straightforward operation. For remote control, automation, or handling large diameters, we offer optional gear operators, pneumatic actuators, or electric actuators. The choice depends on your system's control philosophy and available power sources.
Q6: Does the valve come with any certifications?
A6: Our manufacturing facility is ISO9001 certified, ensuring a consistent quality management process. The valve itself is produced to meet the JIS F7300 standard. Specific product certificates, such as material test reports or pressure test certificates, can be provided upon request.
Q7: What is the typical lead time for an order?
A7: Lead time varies based on order quantity, valve size, and any customizations (like special actuators). For standard sizes and configurations, production can often be expedited. We leverage our efficient supply chain and multiple shipment ports (Shanghai, Guangzhou, Hong Kong, Beijing) to ensure timely delivery worldwide.
Q8: Can you provide technical support for installation or system design?
A8: Yes, as a manufacturer with extensive experience in marine valves, we offer technical support. Our engineers can assist with selection guidance, installation recommendations, and compatibility checks to ensure the valve integrates seamlessly into your ship piping system.
