As a leading manufacturer in the fluid control industry, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our specialized Pneumatic Marine Quick Closing Valve. Designed and built to meet the rigorous demands of maritime applications, this valve is engineered for reliable, instantaneous shut-off in shipboard fuel oil systems. Our commitment to quality, backed by ISO9001 certification and over eight years of manufacturing expertise, ensures you receive a product that prioritizes safety, durability, and operational efficiency for critical marine operations.
This valve is a crucial safety component, mandated for use in fuel oil lines on vessels to prevent fire hazards. Its primary function is to allow for rapid, remote closure of the fuel supply in emergency situations. Constructed from robust materials like cast steel or stainless steel, it withstands the corrosive marine environment and high-pressure conditions typical of fuel systems. The pneumatic actuation provides a fast and powerful closing action, ensuring immediate response when triggered by the ship's safety system.
Key Features and Technical Advantages:
- JIS F7399 Compliance: Manufactured in strict accordance with the Japanese Industrial Standard for marine quick-closing valves, guaranteeing international recognition and suitability for a wide range of vessel types.
- Rapid Closure Mechanism: The pneumatic actuator enables valve closure within seconds, a critical feature for emergency fuel cut-off to minimize risk.
- Dual Control Modes: Offers flexibility with both remote control from the bridge or engine control room and local manual operation for testing or emergencies.
- Robust Construction: The valve body and internal components are made from materials selected for high strength and excellent corrosion resistance, ensuring long service life even in harsh saltwater atmospheres.
- Bubble-Tight Sealing: Features precision-machined seat and disc designs, often with Stellite or similar hard-facing, to achieve and maintain a leak-proof seal, essential for fuel containment.
- Fail-Safe Design: Typically configured to close automatically upon loss of pneumatic pressure or upon receipt of an emergency signal, enhancing system safety.

Frequently Asked Questions (FAQ):
Q1: What is the main purpose of this quick closing valve?
A: Its primary purpose is to provide an immediate and automatic shut-off of the fuel oil supply line on a ship in case of a fire emergency or other hazardous situations, as required by maritime safety regulations.
Q2: Can this valve be operated manually if the pneumatic system fails?
A: Yes, most models include a manual override feature. This allows crew members to close or open the valve locally using a handwheel or lever, ensuring functionality even without pneumatic power.
Q3: Is the JIS F7399 standard recognized internationally?
A: Absolutely. The Japanese Industrial Standard (JIS) is widely respected and accepted in the global maritime industry. Valves built to JIS F7399 are commonly specified and approved for use on vessels worldwide.
Q4: What are the available actuator options for remote control?
A: The standard actuator is pneumatic (air-operated). We can provide valves configured for different control signals, such as simple on/off air pilot valves or models with solenoid valves for integration with electrical fire alarm systems. Specific requirements can be discussed.
Q5: What is the typical closing time for this valve?
A: The closing time is very fast, typically within 3 to 10 seconds depending on the valve size and the specific pneumatic system pressure. This rapid action is crucial for effective emergency response.
Q6: Do you offer different material grades for corrosive service?
A: Yes. While cast steel is standard, we offer stainless steel (CF8/CF8M) bodies and various trim materials (like Stellite) for enhanced resistance against corrosion and erosion, especially important for certain fuel types or aggressive environments.
Q7: How do I determine the correct pressure rating (JIS 10K or 20K) for my application?
A: The required pressure class depends on your system's maximum working pressure and design specifications. Our technical team can assist you in selecting the appropriate rating based on your piping diagrams and operational parameters.
Q8: What documentation is provided with the valve?
A: Each valve is supplied with essential documentation, which typically includes a material test certificate, a detailed dimensional drawing, operation and maintenance instructions, and our ISO9001 quality system certificate. Further certifications are available upon request.
