Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016 and serving global markets with an annual export value of US$1–1.5 million, proudly presents the JIS F7305 Globe Valve for freshwater systems. This valve is engineered with a cast iron body and durable epoxy coating, flanged ends, and a 5K pressure rating, meeting the stringent requirements of the Japanese Industrial Standard (JIS F7305) and backed by BV (Bureau Veritas) certification. Designed to deliver reliable flow control in freshwater applications, our globe valve combines robustness, corrosion resistance, and precision, making it an ideal choice for marine, industrial, and municipal freshwater systems.
As a manufacturer with ISO9001 quality management certification, we ensure each valve undergoes rigorous testing and quality checks. The internal trim is crafted for minimal leakage and smooth operation, while the epoxy coating provides excellent protection against rust and chemical attack in freshwater environments. Whether you need a standard configuration or a customized size, our flexible production capability meets your specific requirements. Below, we detail the key features, technical specifications, and benefits that set our globe valve apart.
Product Features & Advantages
- High-Quality Cast Iron Body: The robust cast iron construction ensures long-term durability and strength under high-pressure conditions. It resists deformation and maintains tight sealing even in demanding freshwater systems.
- Epoxy Coating for Corrosion Resistance: A tough epoxy coating is applied both internally and externally, offering excellent adhesion and protection against moisture, salts, and mild chemicals. This coating significantly extends the valve's service life in freshwater applications.
- Flanged Ends for Easy Installation: The flanged ends (conforming to JIS B2212 or equivalent) provide secure, leak-proof connections. They simplify installation and maintenance, reducing downtime and labor costs.
- Rated 5K (JIS 5K) Pressure Rating: Designed to handle working pressures up to 5 kg/cm² (approx. 0.5 MPa), suitable for typical freshwater pipeline systems. The valve is hydrostatically tested to ensure reliability.
- BV Certified Quality: Bureau Veritas certification confirms that the valve meets international marine and industrial safety standards. This ensures traceability and compliance for projects requiring third-party approval.
- Precision Globe Valve Design: The globe valve's linear motion stem and disc provide accurate flow regulation, throttling, and shut-off capabilities. The valve is suitable for both on/off and control applications.
- Low Maintenance & Long Service Life: The combination of durable materials, protective coating, and precision machining results in minimal wear and tear. Easy-access bonnet and packing gland allow quick servicing.
- Customization Available: We offer optional dimensions (e.g., DN15–DN300), different trim materials (e.g., stainless steel, bronze), and various seating options (metal-to-metal or soft seal) upon request.

Beyond these standard specifications, our JIS F7305 globe valve offers additional benefits:
- Throttling Capability: The linear motion design allows precise flow adjustment, reducing water hammer and system noise.
- Compact & Lightweight: Compared to gate valves of similar rating, globe valves are more compact and lighter, saving space and installation costs.
- Bi-Directional Sealing: The valve can be installed in either direction with minimal leakage, meeting JIS F7305 tightness class.
- Handwheel or Actuator Options: Supplied with a handwheel as standard; gearbox, pneumatic, or electric actuators can be mounted on request.
In real-world applications, our globe valves have been deployed in freshwater cooling systems for ships, water treatment plants, and municipal water supply networks. They consistently demonstrate reliable shut-off and control, even after thousands of cycles.

Frequently Asked Questions (FAQ)
Q1: What is the working pressure for this globe valve?
A: The valve is rated 5K according to JIS standard, which corresponds to a maximum allowable working pressure of approximately 0.5 MPa (5 kg/cm²) for freshwater at normal temperature. The shell is hydrostatically tested at 1.5 times the rated pressure.
Q2: Can this valve be used for seawater or other corrosive fluids?
A: The cast iron body with epoxy coating provides limited corrosion resistance. It is designed specifically for freshwater systems. For seawater or aggressive chemicals, we recommend valves with stainless steel or bronze trim and specialized coatings. Please consult our sales team for customization.
Q3: What sizes are available?
A: Standard sizes range from DN15 to DN300 (1/2” to 12”). Other sizes can be manufactured upon request. Flange dimensions follow JIS 5K standard.
Q4: Is the BV certificate provided with every valve?
A: Yes, each valve is supplied with a BV type approval certificate covering the design and materials. Individual batch certificates can be issued if required.
Q5: What is the difference between globe valve and gate valve for this application?
A: Globe valves provide better throttling and flow control with a linear stem motion, while gate valves are mainly for on/off service. For freshwater systems requiring regulation, the globe valve is the preferred choice.
Q6: Can the valve be installed vertically or horizontally?
A: The valve can be installed in any orientation. However, for easy maintenance, it is recommended to install it with the stem vertical or at a convenient angle for handwheel access.
Q7: Do you offer actuator options?
A: Yes, we can mount pneumatic, electric, or gearbox actuators according to your automation requirements. The mounting flange is prepared according to ISO 5211 standard.
Q8: What is the lead time for this product?
A: Standard sizes are typically shipped within 15-25 working days after order confirmation. Custom orders may take longer. We ship from Shanghai, Guangzhou, Hong Kong, or Beijing ports.
