Frequently Asked Questions (FAQ)
-
Q: What is the main purpose of this valve?
A: This valve is designed as an emergency shut-off device for marine fuel oil lines. Its primary function is to allow crew to quickly and manually stop the flow of fuel in case of fire or other dangerous situations, enhancing onboard safety. -
Q: What does "JIS F7399" and "JIS B2220 5K/10K" mean?
A: JIS F7399 is the Japanese Industrial Standard specifying the requirements for quick-closing valves used on ships. JIS B2220 defines the dimensions and pressure ratings for pipe flanges; 5K and 10K refer to different pressure classes (approximately 5 kgf/cm² and 10 kgf/cm² nominal pressure ratings). -
Q: Is this valve suitable for other fluids besides fuel oil?
A: While designed specifically for marine fuel oil, its bronze construction may be compatible with other non-aggressive fluids like lubricating oil or seawater in certain applications. It is recommended to consult with us for specific media compatibility. -
Q: How does the quick-closing mechanism work?
A: The valve features a manual lever mechanism. In an emergency, pulling or pushing the lever (often with a spring-assisted or cam action) rotates the disc to the closed position rapidly, achieving shut-off in seconds. -
Q: What are the available sizes?
A: Common sizes are available, and custom sizes can be accommodated. Please provide your required nominal pipe size (NPS) or diameter for an accurate quotation. -
Q: Do you offer certifications with the valve?
A: Our manufacturing facility is ISO9001 certified, ensuring a quality management system. Material certificates and test reports are available upon request. -
Q: What is the lead time for orders?
A: Lead time depends on order quantity and specific requirements. Standard items typically have shorter lead times. We provide estimates upon receipt of your inquiry. -
Q: From which ports do you ship?
A: We ship from major Chinese ports including Shanghai, Guangzhou, and Hong Kong, ensuring flexible and efficient logistics to destinations worldwide.
