As a leading manufacturer of industrial valves, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance JIS F7480 Marine Butterfly Valve. Designed specifically for the demanding environments of maritime applications, this valve is engineered to be a reliable and efficient component within Ballast Water Management Systems (BWMS) on cargo ships and tankers. Our commitment to quality, backed by ISO9001 certification and over eight years of manufacturing expertise, ensures that this valve meets the rigorous standards required for safe and compliant marine operations. With an annual export value exceeding US$1 million, our products are trusted by clients across North America, Southeast Asia, Europe, and other major global markets.

The JIS F7480 Marine Butterfly Valve is a critical piece of equipment for managing ballast water, a process essential for vessel stability and safety. Its robust design and precise engineering offer superior performance under high-pressure and corrosive seawater conditions.

Robust Construction & Corrosion Resistance: Manufactured from premium materials like ductile iron, bronze, and stainless steel, the valve body and components offer exceptional strength and resistance to saltwater corrosion, ensuring long service life even in harsh marine environments.
JIS F7480 Compliance: Adherence to the Japanese Industrial Standard (JIS) F7480 guarantees that the valve meets specific dimensional, material, and performance criteria recognized and respected in the global shipbuilding and marine engineering industries.
Excellent Sealing Performance: Equipped with high-quality seat materials such as EPDM, NBR, or PTFE, the valve provides a tight, bubble-tight seal in both directions, preventing leakage and ensuring the integrity of the ballast water system.
Low Torque Operation & Easy Maintenance: The streamlined disc design minimizes flow resistance and operating torque. Available with lever, gear, or electric actuator operation, it allows for easy manual control or seamless integration into automated BWMS.
Versatile Connection Options: Offered in wafer, lug, and flanged types, the valve provides flexible installation solutions to fit various piping layouts commonly found on cargo ships and tankers.

Here is a summary of key technical specifications for common models:

Parameter	Specification
Size Range	DN50 to DN600 (2" to 24")
Pressure Rating	10K, 16K, 20K (JIS Standard)
Body Material	Ductile Iron, Bronze, Stainless Steel (CF8M)

Frequently Asked Questions (FAQ)

Q: What is the primary advantage of a JIS F7480 standard butterfly valve for marine use?
A: The JIS F7480 standard specifies requirements tailored for shipboard valves, ensuring compatibility, durability, and performance that meet the expectations of shipyards and marine engineers worldwide, making it a preferred choice for ballast systems.
Q: Can this valve be used with different types of ballast water treatment systems?
A: Yes, our JIS F7480 butterfly valve is designed as a general-purpose isolation valve for ballast water lines. Its robust construction and material options make it suitable for integration with various BWMS technologies, including filtration, UV, and electrolysis systems.
Q: What are the available actuator options for automated control?
A: We offer optional electric or pneumatic actuators that can be customized to interface with your ship's control system. These actuators enable remote operation and precise flow control for automated ballast management.
Q: How does the valve handle the abrasive nature of ballast water containing sediments?
A: The valve disc is designed with a streamlined profile to minimize turbulence and erosion. Coupled with wear-resistant seat materials like reinforced EPDM or PTFE, it provides good resistance to abrasion from suspended solids.
Q: Is the valve suitable for both freshwater and seawater ballast applications?
A: Absolutely. The material selections, particularly stainless steel components and corrosion-resistant coatings, are chosen to perform reliably in both freshwater and highly corrosive seawater environments.
Q: What is your lead time for standard sizes, and do you offer custom sizes?
A: Standard sizes (DN50-DN600) typically have shorter lead times. For non-standard or custom sizes, our engineering team can provide solutions; please contact us with your specific dimensions for a feasibility assessment and quotation.
Q: Do you provide documentation and certification with the valves?
A: Yes, we provide essential documentation, including material certificates, test reports (shell and seat tests per JIS B 2002), and a certificate of conformity. Detailed certification packages are available upon request.
Q: What after-sales support do you offer for international clients?
A: We provide comprehensive technical support, including installation guidance and maintenance manuals. Spare parts like seal kits are readily available. Our global export experience allows us to assist clients with logistics and customs clearance in our main markets.
