Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents the JIS F7305 Seawater Globe Valve – a premium solution engineered specifically for demanding marine and corrosive environments. As a manufacturer with ISO9001 certification and over 7 years of experience since 2016, we combine precision casting and rigorous quality control to deliver valves that meet the rigorous JIS F7305 standard. This globe valve is designed with a ductile iron body, a 316L stainless steel disc and seat ring, and a flanged connection rated at 1.0MPa (10K), making it the ideal choice for seawater systems, desalination plants, shipbuilding, and offshore platforms.
Key Product Features & Benefits
- Corrosion-Resistant Materials: The valve body is made from ductile iron with an epoxy coating for additional protection against seawater corrosion. The disc and seat ring are crafted from 316L stainless steel, known for its superior resistance to chloride-induced pitting and crevice corrosion, ensuring long service life in harsh marine conditions.
- Precise Flow Control: The globe valve design provides linear flow characteristics, allowing accurate throttling and shut-off. The rising stem with a handwheel offers clear visual indication of valve position, and the backseat design enables packing replacement under pressure.
- High Pressure & Temperature Rating: Rated at 1.0MPa (10K), the valve is suitable for working pressures up to 1.0 MPa and temperatures from -10°C to 120°C (depending on gasket material). Custom temperature ranges are available upon request.
- Flanged Connection: The flanged ends conform to JIS B2220 (10K) standard, providing easy installation and alignment with existing piping systems. Flange facing is standard (RF) and can be customized for special requirements.
- Leak-Free Performance: The valve uses a 316L stainless steel disc lapped to the 316L seat ring for a metal-to-metal seal, ensuring bubble-tight shut-off. Optional soft seal (PTFE or PEEK) can be integrated for enhanced sealing in low-pressure applications.

Frequently Asked Questions
-
Q: Is this valve suitable for potable water?
A: While primarily designed for seawater, the materials (ductile iron with epoxy coating and 316L disc/seat) are also safe for freshwater and many industrial fluids. For potable water, please confirm with our team about coating and seal compatibility. -
Q: What is the maximum working temperature?
A: The standard design temperature range is -10°C to 120°C with standard gaskets. For higher temperatures (up to 200°C), optional graphite gaskets and modified seat materials are available. -
Q: Do you offer actuators (electric/pneumatic)?
A: Yes, we can supply the valve with electric, pneumatic, or hydraulic actuators. Please specify the required voltage, torque, and control type (on/off, modulating) when ordering. -
Q: What sizes are available from stock?
A: We maintain stock for common sizes DN50, DN80, DN100, and DN150 (2", 3", 4", 6"). Other sizes are manufactured with lead times typically 15-30 days depending on quantity. -
Q: Can I get the valve with a soft seal instead of metal-to-metal?
A: Yes, we offer PTFE or PEEK seat inserts for applications requiring tighter shut-off (bubble-tight) at lower pressures. This option is ideal for gas or low-viscosity fluids. -
Q: What is the pressure test standard?
A: Each valve is hydrostatically tested at 1.5 times the design pressure (1.5 MPa) for the shell and 1.1 times for the seat (1.1 MPa) according to JIS B2023 or API 598, depending on customer requirement. -
Q: Do you provide certificates of material origin?
A: Yes, material test certificates (EN 10204 3.1 or equivalent) for the body, disc, and seat ring can be provided upon request. We also issue a certificate of compliance and test reports. -
Q: How can I request a quotation for a customized size?
A: Please contact our sales team with the required size, pressure rating, end connections, and any special requirements. We will respond within 24 hours with a detailed quotation and lead time.
