As a professional manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to introduce our high-performance Corrosion Resistant JIS F7480 Pneumatic Butterfly Valve. Engineered for demanding industrial applications, this valve combines a robust cast steel body with a 304 stainless steel disc, offering exceptional durability and resistance to harsh environments. Our focus on precision manufacturing, backed by ISO9001 certification, ensures each valve delivers consistent performance and long service life, making it a trusted component for fluid control systems worldwide.
This pneumatic butterfly valve is designed to meet the rigorous JIS F7480 standard, commonly specified in marine and industrial piping systems. The key to its performance lies in the material selection and construction. The valve body, crafted from high-grade cast steel, provides the structural integrity needed for high-pressure applications. The disc, made from 304 stainless steel, is highly resistant to corrosion from a wide range of media, including water, chemicals, and seawater. This combination ensures reliable sealing and smooth operation even under challenging conditions. The pneumatic actuator allows for quick and precise on/off or modulating control, which is essential for automated processes. Key advantages of this design include:
- Superior Corrosion Resistance: The 304 stainless steel disc resists pitting and crevice corrosion, significantly extending the valve's lifespan in corrosive environments.
- Robust Construction: The cast steel body withstands high mechanical stress and pressure fluctuations, ensuring system safety.
- Efficient Actuation: The pneumatic actuator provides fast response times and is suitable for remote or centralized control systems.
- Bi-directional Sealing: The valve design allows for effective sealing in both flow directions, enhancing its versatility in pipeline layouts.
- Low Maintenance: The simple yet durable design minimizes the need for frequent maintenance, reducing overall operational costs.
For our B2B clients, the benefits are clear. This valve reduces downtime due to valve failure, lowers long-term replacement costs through its durable materials, and improves process efficiency with reliable pneumatic control. It is an ideal solution for industries where corrosion and reliability are primary concerns. Below is a summary of typical specifications. Please note that specific parameters can be customized to meet your project requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the JIS F7480 standard, and why is it important for this valve?
A: JIS F7480 is a Japanese Industrial Standard specifically for shipbuilding pipeline valves. It defines requirements for design, materials, pressure ratings, and testing. Valves conforming to this standard are recognized for their reliability and safety in marine and other demanding industrial applications. -
Q: Can this valve be used for throttling or flow control, or is it only for on/off service?
A: While primarily designed for reliable on/off isolation, when paired with a suitable pneumatic positioning actuator, this butterfly valve can be used for precise modulating or throttling control of flow rates. -
Q: What are the available options for the seat material, and how do I choose?
A: Common seat materials include EPDM for general water services, NBR for oil applications, and PTFE for high chemical resistance and temperature. The best choice depends on your specific fluid media, temperature, and pressure conditions. -
Q: Is the pneumatic actuator included, and what are the air supply requirements?
A: Yes, the valve is supplied as a complete unit with the pneumatic actuator. Standard air supply pressure is typically 4-7 bar (60-100 psi), but this can be specified according to your plant's compressed air system. -
Q: How does the corrosion resistance of the 304 stainless steel disc perform in seawater applications?
A: AISI 304 stainless steel offers good general corrosion resistance. For prolonged exposure to aggressive seawater or chlorides, we can discuss the option of a 316 stainless steel disc, which provides higher resistance to pitting and is often recommended for marine environments. -
Q: What is the lead time for a custom order with specific size and pressure rating?
A: Lead times vary based on order quantity and specifications. Generally, for standard configurations, we maintain stock for common sizes. For customized orders, our production team can provide a specific timeline upon receipt of your detailed requirements. -
Q: Do you provide technical support and documentation with the valve?
A> Absolutely. Each valve shipment is accompanied by essential documentation, which may include a material test certificate, operation manual, and dimensional drawings. Our engineering team is also available for technical consultations. -
Q: What after-sales services do you offer?
A: We provide comprehensive after-sales support, including guidance on installation and maintenance. For critical components, spare parts like seal kits are available to ensure the long-term operability of your valve.
