Shanghai Zhibang Valve Manufacture Co., Ltd., a professional valve manufacturer established in 2016, proudly presents our high-performance JIS F7300 Standard Marine Ball Valve. Engineered with precision in 304 or 316 stainless steel and featuring a flanged end connection, this valve is specifically designed for demanding marine and offshore applications. Our commitment to quality, backed by ISO9001 certification, ensures that this product offers reliable flow control, exceptional corrosion resistance, and a critical Fire Safe Design certified by API 607, providing a vital safety component for your fluid systems.
This marine ball valve is built to endure the harsh conditions of sea environments. Its core value lies in combining robust construction with stringent international standards.
- Material Excellence: Constructed from 304 or 316 stainless steel, the valve body, ball, and stem offer superior resistance to corrosion, pitting, and crevice corrosion caused by saltwater, chemicals, and various process fluids. This ensures long service life and reduces maintenance costs.
- JIS F7300 Compliance: Manufactured in accordance with the Japanese Industrial Standard (JIS) F7300 for marine valves, guaranteeing dimensional accuracy, performance criteria, and material specifications suitable for shipbuilding and offshore installations.
- API 607 Fire Safe Certification: A paramount feature for safety. The valve is designed and tested to meet API 607 standards for fire-safe valves. In a fire scenario, it maintains a seal to prevent catastrophic leakage, protecting personnel, equipment, and the environment.
- Flanged End Design: The flanged ends facilitate secure and straightforward installation into piping systems using standard bolts. This design ensures a leak-proof connection, simplifies maintenance, and is compatible with common marine piping layouts.
- Operational Reliability: The full-port or standard-port ball design provides excellent flow characteristics with low turbulence and pressure drop. The valve operates smoothly with a quarter-turn action, allowing for quick opening or closing.
- Versatile Applications: Ideal for a wide range of marine systems including ballast systems, fuel lines, cooling water circuits, hydraulic systems, bilge pumping, and cargo handling. Its properties also make it suitable for offshore platforms, coastal industrial plants, and other corrosive environments.

FAQ
Q1: What is the main difference between using 304 and 316 stainless steel for this marine ball valve?
A: 304 stainless steel offers good general corrosion resistance and is cost-effective for many marine applications. 316 stainless steel contains molybdenum, providing significantly higher resistance to chlorides (like saltwater) and acidic environments, making it the preferred choice for more aggressive conditions or where extended longevity is critical.
Q2: Does the "Fire Safe Design" mean the valve will not leak at all during a fire?
A: The API 607 certification means the valve has been tested under rigorous fire simulation conditions. It is designed to maintain a seal and limit leakage to a specified acceptable rate for a defined period after exposure to fire, thereby preventing a major hazardous release. It is a critical safety feature but does not guarantee zero leakage under all extreme scenarios.
Q3: Is this valve suitable for freshwater systems on ships, or only for seawater?
A: It is highly suitable for both. Its corrosion-resistant stainless steel construction protects it from seawater, but it also performs excellently in freshwater cooling systems, fuel lines, hydraulic systems, and other onboard fluid applications where reliability is key.
Q4: Can this valve be operated remotely or automatically?
A: Yes. The standard valve is manual (lever-operated). However, we offer optional gear operators for difficult-to-access locations or electric/pneumatic actuators for integration into automated control systems. Please specify your actuation needs when inquiring.
Q5: What flange standards are compatible with the flanged ends?
A: The valves are typically manufactured with flanges conforming to JIS standards (like JIS B2220) which are common in marine applications. They can also be made compatible with other international flange standards such ASME/ANSI, DIN, or others upon request, depending on your piping specifications.
Q6: How does the JIS F7300 standard benefit me compared to other valve standards?
A: JIS F7300 is a recognized marine-specific standard. Using a valve compliant with this standard ensures it meets the dimensional, material, and performance expectations commonly required in shipbuilding contracts, particularly for projects in Asia or those specifying Japanese standards. It provides assurance of suitability for the marine environment.
Q7: What is the typical delivery time for these valves?
A: For standard sizes and configurations, we maintain inventory for prompt shipment. Delivery times depend on order quantity, specific customization, and destination port. Given our annual export volume and multiple shipment ports (Shanghai, Guangzhou, Hongkong, Beijing), we can typically arrange efficient logistics. Exact timelines are provided upon order confirmation.
Q8: Can you provide valves with different pressure ratings than the standard?
A: Absolutely. Pressure ratings (like JIS 10K, 20K, or others) are customizable based on your system's design pressure. We can manufacture valves to meet specific pressure class requirements. Please provide your needed pressure rating during the inquiry process.
