As a dedicated manufacturer with a strong commitment to quality and international standards, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Standard Compliant JIS F7364 Small Port Bronze Gate Valve. Since our establishment in 2016, we have focused on engineering fluid control solutions that meet the precise demands of global markets, from North America and Europe to Southeast Asia and Africa. This valve is a testament to our manufacturing expertise, designed specifically for applications requiring reliable shut-off in compact piping systems while adhering strictly to the Japanese Industrial Standards (JIS). We provide a comprehensive Mill Test Report with each valve, offering full traceability and peace of mind for engineers, procurement specialists, and project managers who value documented quality assurance.
This valve is engineered for durability and precise performance in demanding environments. Its compact, small-port design makes it an ideal choice for space-constrained installations without compromising on flow capacity or sealing integrity.
Key Features & Technical Advantages:
- Full JIS F7364 Compliance: Manufactured to meet all dimensional, material, and performance requirements of the JIS F7364 standard for bronze gate valves, ensuring global acceptance and interchangeability.
- Superior Bronze Alloy Construction: The valve body, bonnet, gate, and stem are crafted from high-grade bronze (typically JIS H5113 CAC302 or equivalent), offering excellent corrosion resistance against seawater, fresh water, and many non-aggressive chemicals.
- Compact & Lightweight Design: The small port configuration reduces overall weight and space requirements, simplifying installation and supporting system design flexibility.
- Bubble-Tight Shut-Off: Features a precision-machined gate and matched bronze or optional PTFE seats to deliver reliable, leak-free sealing in both directions.
- Rising Stem with Indicator: The outside screw and yoke (OS&Y) design provides clear visual indication of the valve position (open or closed), enhancing operational safety.
- Documented Quality Assurance: Each valve is accompanied by a Mill Test Report (MTR) detailing chemical composition, mechanical properties, and pressure test results, verifying compliance with purchase specifications.

Frequently Asked Questions (FAQ)
-
Q: What exactly does "JIS F7364 compliant" mean for this valve?
A: It means the valve is manufactured to meet all the requirements of the Japanese Industrial Standard F7364, which specifies materials, dimensions, design, testing, and marking for bronze gate valves. This ensures consistent quality, performance, and often interchangeability with other valves made to the same standard. -
Q: Is the Mill Test Report (MTR) provided for every single valve, or just per batch?
A: We provide a Mill Test Report for each valve or for each production lot upon request. The MTR includes specific data like chemical analysis and mechanical test results for the materials used in that particular valve or batch, offering full traceability. -
Q: What are the typical applications for this small port bronze gate valve?
A> It is widely used in plumbing, HVAC systems, shipbuilding (for seawater, ballast, bilge lines), industrial water lines, oil & gas (non-critical utility services), and general service applications involving water, oil, or gas where compact size and bronze's corrosion resistance are beneficial. -
Q: Can this valve be used for steam service?
A: While bronze has good thermal properties, the standard temperature range is -20°C to 120°C. For low-pressure steam applications, please consult with our engineering team to review specific pressure-temperature ratings and recommend suitable seat/packing materials. -
Q: What thread standards are available for the end connections?
A> We commonly offer NPT (American National Pipe Taper), BSPT (British Standard Pipe Taper), and BSPP (British Standard Pipe Parallel) threads. Please specify your required standard when ordering. Other connections like flanged ends can be customized. -
Q: How does the "small port" design differ from a standard port valve?
A> A small port valve has a reduced bore or port opening compared to a full-port valve of the same nominal size. This results in a more compact and lighter valve body, often with a slightly higher pressure drop, making it suitable for systems where space and weight are constraints and full flow area is not critical. -
Q: Do you offer any customization options?
A> Yes, customization is available. Options can include specific stem designs (rising/non-rising), special packing materials, different seat materials (like PTFE), locking devices, gear operators, and specific painting or marking requirements. Contact us with your needs. -
Q: What is your lead time and minimum order quantity (MOQ)?
A> Lead times vary based on specifications and order quantity. For standard configurations, we often have stock or short production cycles. MOQ can be flexible, especially for trial orders. Please inquire for detailed information based on your project timeline.
