ISO9001 (Manufacturing Process)
Shanghai Zhibang Valve Manufacture Co., Ltd. has been a trusted manufacturer of industrial valves since 2016. With an annual export value of US$1 million to US$1.5 million and ISO9001 certification, we ensure every product meets rigorous quality standards. Our JIS F7305 Globe Valve is specifically engineered for marine freshwater distribution systems, combining durability, precision flow control, and long service life. The valve features a robust cast iron body with an epoxy coating for enhanced corrosion resistance, a DN80 flanged connection, and a 5K pressure rating, making it ideal for demanding shipboard applications.
Key Features & Technical Specifications
- Compliant with JIS F7305 Standard: Designed and manufactured strictly according to Japanese Industrial Standard, ensuring interchangeability and reliability in marine systems.
- Cast Iron Body with Epoxy Coating: The high-quality cast iron (GG25 equivalent) provides excellent mechanical strength, while the electrostatic epoxy coating (minimum 250μm thickness) offers superior protection against seawater corrosion and chemical attack.
- DN80 Flanged Connection (5K Rating): Flange dimensions conform to JIS B2220 5K, enabling easy installation and leak-proof sealing with standard gaskets. Suitable for working pressures up to 5 bar (approx. 73 psi).
- Precise Flow Regulation: The globe valve design with a linear motion disc ensures accurate throttling and tight shut-off, minimizing pressure drop and water hammer effects in freshwater lines.
- Marine-Grade Construction: All internal components (stem, disc, seat ring) are made of corrosion-resistant materials (e.g., brass or stainless steel optional) to withstand harsh marine environments.
- Low Maintenance & Long Service Life: Simple structure reduces wear points; repairable seat and packing gland extend operational lifespan. The handwheel operation requires minimal effort.

Advantages for Your Marine System
- Corrosion Resistance: Epoxy coating combined with optional stainless steel internals dramatically reduces rust and pitting, reducing replacement frequency.
- Space-Saving Design: The compact globe valve body fits easily into limited machinery spaces on ships.
- Leak-Free Performance: Precision-machined disc and seat ensure bubble-tight shut-off, critical for freshwater distribution to avoid cross-contamination and pressure loss.
- Easy Integration: Standard DN80 flanges match piping systems without custom adapters, and the 5K pressure rating is common in auxiliary marine systems.
- Global Compatibility: JIS standard is widely accepted across Asia and increasingly recognized in worldwide shipbuilding, making spare parts procurement straightforward.
Our JIS F7305 globe valve has been supplied to numerous shipyards and offshore projects. At Shanghai Zhibang Valve Manufacture Co., Ltd., we maintain strict quality control from raw material incoming inspection through final pressure testing (100% shell and seat test). The ISO9001-certified management system ensures consistent product quality. With a strong export track record to over 15 countries and regions — including North America, Europe, Southeast Asia, and the Middle East — we have the capacity to fulfill both small and large orders efficiently. Our annual export value of US$1 million+ reflects the trust global customers place in our products.
Frequently Asked Questions (FAQ)
-
Q: Can this valve be used for seawater instead of freshwater?
A: While the standard cast iron + epoxy coating offers good resistance to freshwater, for seawater applications we recommend upgrading internal materials (e.g., stainless steel disc and seat) available upon request. Please consult our sales team for customization options. -
Q: What is the maximum working temperature of this valve?
A: The standard design is suitable for -10°C to 80°C. For higher temperatures (up to 150°C), alternative coatings or material adjustments may be needed. Contact us for specific temperature requirements. -
Q: How often does the valve require maintenance?
A: Globe valves generally need only periodic inspection of the packing gland and seat tightness. Under normal marine freshwater conditions, we recommend checking every 6 months. The repairable seat design allows easy refurbishment without replacing the entire valve. -
Q: Is the flange drilling pattern compatible with other JIS flanges?
A: Yes, our valve flanges are machined to JIS B2220 5K standard (10 bolt holes for DN80). They match standard JIS blind flanges and gaskets. For other standards (e.g., DIN, ANSI), adapters are available. -
Q: What is the typical lead time for this product?
A: For standard DN80 JIS F7305 globe valves, lead time is approximately 15-25 days after order confirmation, depending on quantity. Customizations (different material, coating color) may extend the time. We can provide a precise schedule upon inquiry. -
Q: Do you provide a warranty?
A: Yes, we offer a 12-month warranty from the date of shipment against manufacturing defects. The warranty covers material and workmanship issues under normal service conditions. Extended warranty options are negotiable. -
Q: How is the valve packed for export?
A: Each valve is individually wrapped in plastic, with flange faces protected by wooden end caps. They are packed in strong plywood crates or cartons, suitable for sea freight. Custom packing (e.g., vacuum packing, seaworthy cases) is available upon request. -
Q: Can I get a sample order before bulk purchase?
A: Absolutely. Sample orders are welcome. The sample cost will be charged and later deducted from your first bulk order. Please note that freight for samples is usually paid by the buyer. Contact our sales team for further details.
