As a dedicated manufacturer with a strong focus on marine fluid control solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our JIS F7399 Quick Closing Valve. Engineered to meet stringent maritime safety standards, this valve is a critical component for shipboard systems where rapid isolation of pipelines is paramount. Our years of experience since 2016 in supplying reliable valves to global markets ensure that this product combines robust construction with precise functionality, offering shipbuilders and marine operators a dependable safeguard against potential hazards.
The core value of our JIS F7399 valve lies in its rapid and reliable shut-off capability, designed to automatically or manually close within seconds upon activation, thereby preventing the spread of fire or the uncontrolled release of hazardous fluids. Manufactured under our ISO9001 certified quality management system, each valve undergoes rigorous testing to guarantee performance that aligns with international marine safety protocols. We understand the demanding environments of marine applications, which is why our valves are built to deliver durability and peace of mind.
Detailed Product Features & Technical Specifications:
- Standard Compliance: Designed and manufactured in strict accordance with the Japanese Industrial Standard JIS F7399, ensuring acceptance in shipbuilding and repair yards worldwide.
- Robust Construction: The valve body and critical components are typically crafted from high-grade cast steel, bronze, or optional stainless steel, providing excellent resistance to corrosion, seawater, and high-pressure conditions.
- Quick-Acting Mechanism: Incorporates a spring-assisted or weighted lever mechanism that ensures swift closure. The design minimizes closure time, a vital factor for emergency scenarios.
- Versatile Actuation Options: Available in standard manual lever operation. Remote activation systems—such as hydraulic, pneumatic, or combined remote/manual controls—are customizable to integrate with your vessel's safety and control systems.
- Leak-Tight Sealing: Features precision-machined seats and seals (often metal-to-metal or resilient materials) that ensure a bubble-tight seal in the closed position, preventing any leakage of flammable or dangerous liquids.
- Easy Installation & Maintenance: Standard flanged connections simplify installation into existing pipelines. The design often allows for in-line maintenance without complete removal, reducing downtime.
Primary Applications: This valve is specifically designed for marine service, including:
- Fuel oil transfer and service lines
- Lubricating oil systems for main and auxiliary engines
- Cargo piping systems on tankers
- Other shipboard pipelines carrying flammable or hazardous fluids where quick isolation is required by safety regulations.

Frequently Asked Questions (FAQ):
Q1: What is the primary function of a JIS F7399 Quick Closing Valve?
A: Its primary function is to provide rapid isolation of a pipeline in an emergency, such as a fire, to prevent the spread of flammable fluids. It is a critical safety device mandated for certain shipboard systems.
Q2: Can this valve be used for applications other than marine?
A: While specifically designed and certified to JIS F7399 for marine use, its robust quick-closing design could be suitable for other industrial applications requiring fast emergency shut-off. However, its compliance is specifically for maritime standards.
Q3: What are the available remote activation methods?
A: We offer optional remote activation systems including hydraulic and pneumatic actuators. These can be configured to close the valve from a remote location like the ship's bridge or engine control room.
Q4: How do I know which material (cast steel, bronze, stainless steel) is right for my service?
A: Material selection depends on the fluid media, pressure, temperature, and corrosion requirements. Cast steel is common for fuel oil, bronze is often used for seawater or less aggressive media, and stainless steel offers higher corrosion resistance. Our technical team can advise based on your specific parameters.
Q5: Are the flanges compatible with ANSI or DIN standards, or only JIS?
A> While the valve design complies with JIS F7399, we can manufacture it with flanges to match various standards, including JIS, ANSI, and DIN, to ensure proper integration with your existing piping.
Q6: What is the typical lead time for an order?
A: Lead time varies based on order quantity, size, material, and customization. Standard configurations typically have shorter lead times. We provide accurate timelines upon receipt of your detailed inquiry.
Q7: Do you provide documentation like test certificates and material reports?
A: Yes, as an ISO9001 certified manufacturer, we can provide standard documentation, including pressure test certificates and material chemical/physical test reports, upon request.
Q8: Can the valve be manually operated if the remote system fails?
A: Absolutely. Many of our remote-actuated models include a manual override feature, such as a handwheel or lever, allowing direct manual operation in case of power or system failure, ensuring fail-safe functionality.
