As a specialized manufacturer of industrial valves since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is committed to providing reliable fluid control solutions for demanding sectors. Our JIS F7481 Stainless Steel Butterfly Valve is engineered specifically for the rigorous conditions of shipbuilding and offshore platforms. This valve combines the corrosion resistance of stainless steel with the precise design requirements of the Japanese Industrial Standard, offering a durable, efficient, and cost-effective solution for marine piping systems. With an annual export value demonstrating our global reach, we understand the critical need for valves that perform reliably in harsh saltwater environments.
Core Product Features & Technical Advantages:
- JIS F7481 Compliance: Manufactured to meet the Japanese Industrial Standard F7481, which specifies dimensions, materials, and performance criteria for butterfly valves used in shipbuilding. This ensures compatibility and reliability in marine applications.
- Premium Stainless Steel Construction: The body, disc, and stem are typically crafted from grades like 304 or 316 stainless steel, providing excellent resistance to corrosion from seawater, chemicals, and atmospheric exposure on offshore structures.
- Optimized for Marine Service: Designed specifically for ship piping systems (ballast, cooling, bilge, etc.) and offshore platform utilities (firewater, process lines). The design considers factors like vibration, thermal cycling, and high humidity.
- Versatile Actuation Options: Available with manual handwheel, gear operator, pneumatic actuator, or electric actuator to suit different control and automation needs on vessels and platforms.
- Secure Sealing Performance: Utilizes resilient seat materials such as EPDM or PTFE, which ensure tight shut-off and long service life even with abrasive or corrosive media.
- Compact & Lightweight Design: The butterfly valve design offers a lower profile and weight compared to many other valve types, which is a significant advantage in space-constrained marine installations.

Frequently Asked Questions (FAQ):
-
What is the significance of the JIS F7481 standard for this valve?
JIS F7481 is a Japanese Industrial Standard specifically for butterfly valves used in shipbuilding. It defines dimensions, materials, testing methods, and marking requirements, ensuring the valve is fit for marine service. Using a JIS-compliant valve can facilitate compliance in projects where these standards are referenced. -
Can this valve be used with seawater?
Yes, the stainless steel construction (typically 316 grade offers better resistance) is chosen for its corrosion resistance against seawater. The seat material (like EPDM) is also selected to handle seawater without degrading quickly. -
What are the available connection types?
The valve is primarily offered in wafer style (installed between two pipe flanges with bolts) and lug style (has threaded holes for bolting to a single flange). The choice depends on your piping design and installation preference. -
Is the valve suitable for high-pressure applications on offshore platforms?
The valve is built to the pressure rating specified in JIS F7481, which covers common marine system pressures. For specific high-pressure requirements, please consult with us to confirm suitability or explore customized options. -
What actuation methods can be provided?
We can supply the valve with a manual lever or handwheel, a gear operator for larger sizes, or automated actuation via pneumatic or electric actuators. The actuation method is often customizable based on your system design. -
How does the ISO9001 certification benefit the buyer?
Our ISO9001 certification indicates a systematic approach to quality control throughout manufacturing. It provides assurance of consistent product quality, reliable performance, and professional processes behind the valve you receive. -
What is the typical delivery lead time?
Lead times vary based on size, configuration, and order quantity. Standard sizes and configurations may have shorter lead times. We can provide estimated timelines upon request based on your specific order. -
Can you provide valves in sizes outside the typical DN50-DN600 range?
Yes, custom sizes can be explored. Please contact our technical team with your specific size requirements to discuss feasibility and manufacturing options.
