As a leading valve manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-performance fluid control solutions for demanding marine environments. Our Marine Butterfly Valve, designed specifically for offshore platform ballast water treatment systems, represents our commitment to reliability and durability. Built to the stringent JIS F7480 10K standard, this valve ensures safe and efficient operation in the harsh conditions of the sea, protecting your critical systems and contributing to environmental compliance. With over US$1 million in annual exports to global markets including North America, Southeast Asia, and Europe, our products are trusted by offshore operators worldwide for their robust construction and consistent performance.
This marine-grade butterfly valve is engineered to handle the challenging requirements of ballast water treatment, where corrosion resistance and long-term sealing integrity are paramount. The compact and lightweight design of the wafer or lug type body allows for easy installation and maintenance in the confined spaces typical of offshore platforms. The valve's disc is precision-machined to provide a bubble-tight shut-off, essential for preventing cross-contamination during ballast operations. Key advantages include:
- Superior Corrosion Protection: Critical components are made from materials like stainless steel or coated ductile iron to withstand saltwater exposure, preventing premature failure.
- Low Maintenance Design: The simple construction with minimal moving parts reduces the need for frequent servicing, lowering your total cost of ownership.
- Excellent Flow Control: The streamlined disc design minimizes pressure drop across the valve, ensuring efficient pumping and reduced energy consumption for ballast transfer.
- Versatile Actuation Options: Available with manual levers, gear operators, or electric actuators to suit your specific control system requirements and automation level.

The benefits of choosing our valve extend beyond the specifications. For ballast water treatment systems, the reliable sealing performance ensures compliance with international regulations by preventing leakage. The JIS F7480 standard guarantees compatibility with other Japanese-standard piping components commonly used in marine construction. Furthermore, the valve's robust design translates to a longer service life, reducing replacement frequency and associated downtime on your expensive offshore asset. Our valves are designed to be operator-friendly, with clear position indicators on manual versions and smooth operation even after prolonged periods of inactivity.
Backed by our established manufacturing expertise since 2016 and a proven export track record, you can be confident in the quality and reliability of every valve we supply. Our products are shipped from major Chinese ports like Shanghai and Guangzhou, ensuring timely delivery to your global projects. We understand the critical nature of offshore operations, and our Marine Butterfly Valve is built to meet that challenge.

Frequently Asked Questions (FAQ):
Q1: What is the main advantage of a JIS F7480 standard valve for marine use?
A: The JIS F7480 standard is specifically developed for marine valves, ensuring they meet rigorous requirements for materials, pressure ratings, and dimensions suitable for ship and offshore platform piping systems, offering assured compatibility and reliability.
Q2: Can this valve be used with seawater directly?
A: Yes, when configured with appropriate materials like stainless steel (SS316) body/disc and EPDM or PTFE seats, the valve offers excellent corrosion resistance against seawater, making it ideal for ballast water applications.
Q3: What does the pressure rating "10K" mean?
A: "10K" indicates a pressure rating of 10 kgf/cm², which is approximately equivalent to PN16 (16 bar). It defines the maximum allowable working pressure the valve can withstand.
Q4: Are electric actuators available for remote operation?
A: Absolutely. Electric actuators are a popular option for integration into automated ballast water treatment control systems, allowing for remote open/close commands and position feedback.
Q5: What is the typical delivery time for a standard size valve?
A: For standard sizes and materials, delivery typically takes 4-6 weeks after order confirmation. Lead times for customized or large-size valves may vary and can be confirmed upon inquiry.
Q6: Do you provide material certificates for the valves?
A> Yes, as an ISO9001 certified manufacturer, we can provide material test certificates (MTC) and other relevant documentation for the valves upon request to support your quality assurance processes.
Q7: Is the valve suitable for other fluids besides seawater?
A> While designed for marine service, with the correct seat and body material selection, it can handle various fluids including fresh water, oils, and certain chemicals. Please consult with our engineers for specific media compatibility.
Q8: What kind of after-sales support do you offer?
A> We provide technical support for installation and operation. A standard warranty covers manufacturing defects. Spare parts like seals and gaskets are also available for purchase to facilitate maintenance.
