As a dedicated manufacturer with ISO9001-certified quality management since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing reliable marine valves for global markets. Our JIS F7399 Pneumatic Quick Closing Valve is engineered specifically for the critical task of managing fuel flow on ships. It combines rapid response with robust construction to ensure operational safety and efficiency in marine fuel systems, offering a dependable solution for shipbuilders, shipowners, and maintenance crews worldwide.
This valve is designed to meet the stringent requirements of marine applications. Its primary function is to quickly isolate fuel lines in response to a pneumatic signal, which is crucial for emergency shutdowns or routine operational control. The design adheres to the Japanese Industrial Standard (JIS) F7399, ensuring compatibility and reliability within standardized marine piping systems.
- Rapid Closure Mechanism: The pneumatic actuator enables swift valve closure within seconds, a vital feature for preventing fuel spillage or controlling flow during emergencies.
- Robust Construction: Manufactured from high-grade cast steel or stainless steel options, the valve body withstands the corrosive marine environment and the mechanical stresses of shipboard operation.
- Standard Compliance: Compliance with JIS F7399 guarantees that the valve's dimensions, pressure ratings, and performance align with industry norms, facilitating easier integration into ship designs.
- Flanged Connections: Standard flanged ends (e.g., JIS 10K/20K flange standards) ensure secure and leak-proof integration into the ship's fuel piping network.
- Manual Override Option: Many models include a manual override mechanism, allowing crew members to operate the valve locally if the pneumatic system is unavailable.
- Remote Control Capability: The valve can be integrated into the ship's central control system, enabling operators to open or close it from a remote location like the engine control room.
The technical specifications of the valve are tailored for fuel service. Below is a summary of common parameters; specific values may vary by model and customer requirements.

| Sealing Material | PTFE, reinforced elastomers |
| Flange Standard | JIS 10K, 20K, or compatible |
Choosing this valve brings several concrete benefits to your marine operations:
- Enhanced Safety: The quick-closing feature acts as a critical safety component, allowing for immediate isolation of fuel lines in case of fire, leak, or other hazardous situations.
- Operational Efficiency: Remote pneumatic control reduces the need for manual intervention at the valve location, saving time and labor during routine operations or emergency procedures.
- System Reliability: Built to marine standards with durable materials, the valve offers long service life and minimal maintenance, reducing downtime and replacement costs.
- Regulatory Compliance: Using a JIS-standardized valve helps meet design and equipment requirements for many shipbuilding and classification standards.
- Flexible Integration: Available in various sizes and with optional features like manual override, it can be customized to fit specific ship designs and control system architectures.

Frequently Asked Questions (FAQ)
Q1: What is the main purpose of this pneumatic quick closing valve?
A: Its primary purpose is to provide rapid shut-off of fuel lines on ships. Upon receiving a pneumatic signal (typically from a control panel or emergency system), the valve closes swiftly to stop fuel flow, which is essential for safety during emergencies or for operational control.
Q2: Does this valve comply with international standards other than JIS?
A: While the valve is designed and manufactured to meet the specific requirements of the JIS F7399 standard, its dimensions and pressure ratings may be compatible with other international flange and valve standards. Customers should provide their specific standard requirements for confirmation.
Q3: Can the valve be operated manually if the pneumatic system fails?
A: Yes, many models of this valve include an optional manual override feature. This allows crew members to open or close the valve using a handwheel or lever directly on the valve, providing a backup control method.
Q4: What materials are available for the valve body?
A: The standard body material is cast steel (e.g., SC450), suitable for general marine fuel service. For applications requiring higher corrosion resistance, such as with certain fuel types or in more aggressive environments, stainless steel options (like SS304 or SS316) are available upon request.
Q5: What is the typical closure time for this valve?
A: The closure time is designed to be quick, typically under 3 seconds from the moment the pneumatic signal is received to the valve being fully closed. This rapid action is key to its safety function.
Q6: What size ranges are available?
A: The valve is commonly available in nominal diameters (DN) from DN50 (approximately 2 inches) up to DN300 (approximately 12 inches). Other sizes may be customizable based on project needs.
Q7: What air pressure is required to actuate the pneumatic system?
A: The standard actuating air pressure range is 0.5 to 0.7 MPa. The valve's pneumatic actuator is designed to operate reliably within this pressure range, which is common in shipboard compressed air systems.
Q8: Is the manufacturer certified for quality management?
A: Yes, Shanghai Zhibang Valve Manufacture Co., Ltd. holds an ISO9001 certification for its quality management system. This certification ensures that our manufacturing processes are controlled and consistent, aiming for reliable product quality.
