Shanghai Zhibang Valve Manufacture Co., Ltd proudly presents the JIS F7305 Globe Valve specifically engineered for seawater service. As a manufacturer established in 2016 with an annual export value exceeding US$1 Million, we understand the harsh demands of marine environments. This valve features a ductile iron body combined with a 316L stainless steel stem and disc, providing exceptional corrosion resistance and durability. Designed with a 10K flanged connection per JIS standard, it ensures reliable sealing and easy installation in piping systems.
Our globe valve is the optimal solution for controlling flow in seawater cooling, desalination plants, and offshore platforms. The 316L stem and disc resist pitting and crevice corrosion even in high-chloride environments, while the ductile iron body offers superior strength compared to cast iron. Backed by ISO9001 certification, each valve undergoes rigorous quality checks to meet international standards.
Key Features & Technical Specifications
- Compliant Standard: JIS F7305 – ensures dimensional interchangeability and reliable performance.
- Body Material: Ductile Iron (FCD-S) – high tensile strength, excellent impact resistance, and good machinability.
- Stem & Disc Material: AISI 316L Stainless Steel – superior corrosion resistance, especially against seawater chlorides.
- Connection Type: Flanged, JIS 10K (PN16 compatible) – flat face or raised face optional.
- Pressure Rating: 10K (approx. 1.0 MPa at ambient temperature).
- Operation: Handwheel or optional pneumatic/electric actuator (available upon request).
- Seat Sealing: Metal-to-metal (316L disc to integral seat) for bubble-tight shut-off.
- Applicable Fluids: Seawater, brackish water, cooling water, and other corrosive media.
- Temperature Range: -10°C to +120°C (for standard PTFE packing; high-temp packing optional).
- Testing: Hydraulic shell test at 1.5× rated pressure, seat test at 1.1× rated pressure.

Design Advantages & Customer Benefits
- Long Service Life in Seawater: 316L components prevent rust and galvanic corrosion, reducing maintenance frequency.
- High Strength & Light Weight: Ductile iron offers up to 2× the yield strength of cast iron, allowing thinner walls and easier handling.
- Bubble-Tight Shut-Off: Precision machined seat and disc provide Class VI (ANSI FCI 70-2) sealing for zero leakage.
- Easy Installation: JIS 10K flanges directly connect to standard marine piping systems without adapters.
- Customizable Operation: Gearbox or actuator options available for automated systems; handwheel for manual use.
- Low Torque Operation: Optimized disc profile reduces operating torque, saving energy and wear on actuators.
- Global Shipping: We ship from Shanghai, Guangzhou, Hong Kong, and Beijing to markets worldwide, including North America, Europe, Middle East, and Southeast Asia.

Frequently Asked Questions (FAQ)
-
Q: Can this valve be used for freshwater or other non-corrosive fluids?
A: Yes, it is suitable for freshwater, cooling water, and many neutral fluids. However, for non-corrosive applications, a lower-cost cast iron valve might be sufficient. We recommend contacting our sales team to evaluate your specific media. -
Q: What is the maximum working pressure at elevated temperatures?
A: The JIS 10K rating is typically 1.0 MPa at ambient temperature. At 100°C, the allowable pressure reduces to approximately 0.8 MPa. For higher temperature requirements, please specify; we can offer graphite packing and special gaskets. -
Q: Do you provide pneumatic or electric actuated versions?
A: Yes, we can supply the valve pre-assembled with a pneumatic diaphragm actuator or electric actuator according to your control requirements. Actuator size and torque calculations are available upon request. -
Q: Is the valve certified for contact with drinking water?
A: The ductile iron body and 316L components are generally inert. If you need a certification for potable water (e.g., WRAS, NSF), please inform us before ordering, as we can adjust the internal coating and sealing materials accordingly. -
Q: What is the typical lead time?
A: For standard sizes (DN50 – DN200), lead time is 15–25 working days. Custom sizes or special materials may require 30–45 days. We can expedite for urgent orders subject to stock availability. -
Q: How do you protect the valve during shipment to avoid damage?
A: Each valve is individually wrapped in anti-rust paper, packed in a plywood case or carton with foam support. Flanges are covered with plastic caps. For sea freight, we use fumigated wooden crates. -
Q: Can you provide a material test certificate (MTC) for the 316L stem and disc?
A: Yes, we can issue MTCs from our mill supplier for the 316L material. A third-party inspection by SGS, BV, or similar is also available at an additional cost. -
Q: What is the difference between this JIS F7305 and a standard globe valve?
A: JIS F7305 specifies face-to-face dimensions, flange drilling, and design features specifically for Japanese standard piping. It is equivalent to BS or DIN globe valves but with distinct dimensions. Please verify your existing flange standard before ordering.
