As a professional manufacturer with years of experience, Shanghai Zhibang Valve Manufacture Co., Ltd is proud to present the JIS F7306 5K Angle Globe Valve with Bronze Trim, Flanged Ends, and Non-Rising Stem. Designed specifically for Japanese Industrial Standard (JIS) 5K piping systems, this valve delivers reliable flow control and shut-off under moderate pressure conditions up to 0.7MPa. The bronze trim ensures excellent corrosion resistance and long service life, while the non-rising stem design minimizes installation space and enhances operational safety. With our ISO9001 certified production processes and a dedicated export team serving global markets, you can trust this valve for your demanding applications.
This angle globe valve is constructed with a robust cast iron or ductile iron body (optional), offering durability and cost-effectiveness. The flanged ends provide easy and secure connection to standard JIS 5K flanges, simplifying installation and maintenance. The 0.7MPa hydraulic test guarantees the integrity of the valve under pressure, ensuring zero leakage at the seat and stem seals. Whether you need it for water treatment, HVAC systems, oil handling, or general industrial pipelines, this valve is engineered to perform consistently.
Key Features & Technical Specifications
- JIS F7306 Compliant: Manufactured strictly according to Japanese Industrial Standard F7306, ensuring dimensional and performance compatibility with JIS 5K systems.
- Bronze Trim (Disc & Seat): Bronze internal components offer superior resistance to corrosion, erosion, and wear, extending valve life in chemically aggressive fluids.
- Non-Rising Stem (NRS): The stem does not rise when the valve is opened, allowing installation in tight spaces (e.g., underground pits or confined areas) and reducing stem seal wear.
- Flanged Ends: Standard JIS 5K flanges with raised face, providing a leak-tight joint with matching pipeline flanges using gaskets and bolts.
- 0.7MPa Hydraulic Test: Each valve is hydrostatically tested at 0.7MPa (approximately 1.5 times rated pressure) to validate shell and seat sealing performance.
- Angle Pattern: The 90-degree flow path reduces pressure drop and minimizes turbulence, making it ideal for applications requiring low resistance and space-saving installation.
- Bi-directional Sealing: Designed for flow in either direction, though best performance is achieved with flow under the disc.
- Easy Maintenance: The bonnet is bolted to the body, allowing quick access to internal parts for inspection or replacement without removing the valve from the pipeline.

Advantages for Your Application
- Space Saving: The non-rising stem design reduces the overall height of the valve, making it perfect for installations where headroom is limited.
- Corrosion Resistance: Bronze trim ensures reliable operation even in water containing chlorides, mild acidic or alkaline fluids, and condensing steam.
- Low Torque Operation: The angle pattern and smooth sealing surfaces reduce the handwheel torque required, allowing easy manual operation even after long periods of inactivity.
- Long Service Life: All internal moving parts are made of bronze and stainless steel, resisting galling and seizure. The valve is designed for frequent throttling and shut-off cycles.
- Versatile Media Compatibility: Suitable for water, oil, gas, steam, and many non-aggressive fluids. For special media, valve materials can be adapted upon request.
- Global Standards Compatibility: JIS 5K flanges are widely used in Japan, Southeast Asia, and many other regions. The valve can also be adapted to DIN or ANSI flanges with custom machining.

Frequently Asked Questions (FAQ)
-
Q: What is the working pressure of this valve?
A: The JIS F7306 5K valve is designed for a maximum working pressure of 0.7MPa (about 7 bar). Each valve is hydrostatically tested at 0.7MPa to ensure safety and sealing. -
Q: Can this valve be used for steam service?
A: Yes, it is suitable for low-pressure steam systems up to 0.7MPa. For higher temperature applications, please consult us for suitable seat material upgrades. -
Q: What flange standard does it comply with?
A: The flanges are machined to JIS 5K standard (raised face). They match JIS B2220 5K flanges. We can also supply adapters or custom flanges upon request. -
Q: Is the valve bidirectional?
A: The valve can be installed in either direction, but maximum flow capacity and smooth throttling are achieved when flow enters under the disc (direction indicated by arrow on body). -
Q: What is the advantage of a non-rising stem compared to a rising stem?
A: The non-rising stem design keeps the stem height constant during operation, saving vertical space and protecting the stem from external damage. It also reduces stem seal wear because the stem does not move through the packing. -
Q: What body materials are available?
A: Standard body material is cast iron. Ductile iron is available as an option for higher strength. If you require stainless steel or other materials, please contact us for customization. -
Q: How is the valve tested before shipment?
A: Each valve undergoes a 0.7MPa hydrostatic shell test and a seat leakage test. We also perform random torque and dimensional checks as part of our ISO9001 quality system. -
Q: Do you provide certificates like material test reports or dimensional reports?
A: Yes, we can provide material certificates, test reports, and a certificate of conformity upon request. Please specify your requirements when ordering.
