As a professional manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance industrial valves for global markets. Our JIS F7481 Marine Butterfly Valve represents our commitment to quality and reliability, engineered specifically for demanding marine applications. This valve is offered with full OEM support, accompanied by a Mill Test Report for complete material traceability and backed by a comprehensive warranty, providing shipbuilders and marine system integrators with a dependable flow control solution they can trust.

Designed in strict compliance with the Japanese Industrial Standard JIS F7481, this butterfly valve meets the rigorous requirements for valves used in ship piping systems. Its robust construction ensures reliable operation in controlling the flow of seawater, ballast water, bilge systems, fuel oil, and other marine fluids.

Key Features & Technical Advantages:

Standard-Compliant Design: Manufactured precisely to JIS F7481 specifications, ensuring compatibility and performance in marine environments recognized by international shipbuilding standards.
Superior Material Selection: Available in body materials like cast steel (SC450), stainless steel (CF8/CF8M), and ductile iron, paired with seat options such as EPDM, NBR, PTFE, or metal for different media and temperature ranges.
OEM & Customization Flexibility: We offer complete OEM services, including custom markings, packaging, and configuration of operation types (lever, gear, electric, or pneumatic actuation) to match your specific system design.
Enhanced Reliability & Safety: The disc design minimizes pressure drop and turbulence. A robust stem design with effective sealing prevents leakage, which is critical for shipboard safety and environmental protection.
Full Documentation & Traceability: Each valve is supplied with a Mill Test Report (MTR) detailing the chemical composition and mechanical properties of the materials used, providing essential documentation for quality audits and system certifications.
Operational Efficiency: The 90-degree quarter-turn operation allows for quick opening and closing. Low torque requirements enable the use of compact and cost-effective actuators.

Frequently Asked Questions (FAQ):

Q: What is the significance of the JIS F7481 standard for this valve?
A: JIS F7481 is the Japanese Industrial Standard for butterfly valves used in ship piping systems. Compliance ensures the valve's design, dimensions, pressure ratings, and materials are suitable for the harsh conditions and safety requirements of marine applications.
Q: What does "OEM" mean in your product offering?
A: OEM stands for Original Equipment Manufacturer. We can produce these valves with your company's brand name, logos, specific packaging, and even minor design modifications to meet your private label or system integration needs.
Q: Why is a Mill Test Report important?
A: An MTR is a certified document from the material mill that verifies the chemical and physical properties of the metal used in the valve body and components. It is crucial for quality traceability, material verification, and is often required for marine classification society approvals.
Q: What is covered under the "Full Warranty"?
A: Our warranty covers defects in materials and workmanship under normal use for a specified period. Exact terms, including duration and coverage scope, are provided with the commercial contract. It demonstrates our confidence in the product's quality.
Q: Can you provide valves with different end connections or face-to-face dimensions?
A: Yes. While standard valves conform to JIS F7481 dimensions, we can customize connection types (e.g., specific flange standards like JIS, ANSI) and face-to-face lengths upon request to fit your existing piping.
Q: What seat materials do you recommend for seawater service?
A: For seawater, we typically recommend EPDM or PTFE seats for general service, and metal-seated (e.g., stainless steel) versions for high-temperature or abrasive applications. The best choice depends on specific temperature, pressure, and fluid characteristics.
Q: Do you supply actuators with the valves?
A: Yes, we can supply the valves as manual units (lever/gear) or pre-assembled with electric or pneumatic actuators from selected partners. We ensure proper sizing and mounting for a complete, ready-to-install package.
Q: What are your main export markets and shipping terms?
A: We export to a wide range of regions including North America, Europe, Southeast Asia, Africa, and Oceania. We ship from major ports like Shanghai, Guangzhou, Hong Kong, and Beijing under standard international trade terms (FOB, CIF, etc.).
