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. Our Marine JIS F7305 Globe Valve, available in sizes DN50 to DN200 with 10K flanged ends and 316L stainless steel internals, is specifically engineered for reliable flow control in marine environments. Built to withstand harsh conditions, this globe valve combines durability, precision, and corrosion resistance—making it an ideal choice for shipbuilding and offshore applications.
Product Features & Technical Specifications
- Compliance with JIS F7305 Standard: Manufactured strictly according to Japanese Industrial Standard F7305, ensuring dimensional consistency and interchangeability in marine systems.
- 316L Stainless Steel Internals: The valve seat, disc, and stem are made from 316L stainless steel, offering superior resistance to seawater corrosion, chloride stress corrosion cracking, and pitting.
- 10K Pressure Rating: Rated for 10K (approximately 1.0 MPa) working pressure, suitable for medium-pressure marine piping.
- Flanged Ends (RF or FF): Standard raised face or flat face flanges per JIS B2210 provide easy installation and leak-free connections.
- Manual Handwheel Operation: With a robust handwheel and rising stem design for clear visual indication of valve position.
- Body Materials Options: Available in cast iron, ductile iron, or carbon steel bodies (customizable per request).
- Bi-Directional Sealing: Offers positive shut-off in both flow directions.

Frequently Asked Questions (FAQ)
-
Q1: Is this globe valve suitable for seawater applications?
A: Yes, the 316L stainless steel internals provide excellent corrosion resistance in seawater environments. The body material options (cast iron, ductile iron, carbon steel) may require additional coating for direct seawater contact; we recommend carbon steel with epoxy coating or a fully 316L body upon request. -
Q2: What is the maximum working pressure at 100°C?
A: The 10K rating derates with temperature. At 100°C, the allowable working pressure is approximately 0.9 MPa (130 psi). For detailed pressure-temperature ratings, please refer to the technical datasheet provided with the order. -
Q3: Do you offer non-rising stem versions?
A: Standard design is rising stem. Non-rising stem (NRS) is available as a custom option for limited installation spaces. Please specify when ordering. -
Q4: What flange facing is standard?
A: Standard is raised face (RF) per JIS B2210. Flat face (FF) is also available for cast iron bodies to match mating flanges. -
Q5: Can I get a gear-operated actuator instead of handwheel?
A: Yes, for larger sizes (DN150 and above) or where torque reduction is needed, gearbox actuation is optional. Contact our sales team for details. -
Q6: What tests are performed on each valve?
A: Each valve undergoes hydrostatic shell test (1.5x rated pressure) and seat leakage test (1.1x rated pressure) in accordance with JIS B2003. Test certificates can be provided. -
Q7: What is the lead time for standard DN50-DN200 sizes?
A: For standard quantities (10-50 units), lead time is approximately 20-30 days after order confirmation. Rush orders can be expedited upon request. -
Q8: Does Shanghai Zhibang provide OEM/private labeling?
A: Yes, we offer OEM services with custom branding, packaging, and documentation. Minimum order quantities apply.
