Shanghai Zhibang Valve Manufacture Co., Ltd., a professional manufacturer established in 2016 with ISO9001 certification, proudly introduces the JIS F7312 16K Marine Grade Cast Steel Globe Valve. Designed specifically for demanding marine, ballast system, and offshore platform applications, this valve combines robust cast steel construction with precision engineering to ensure reliable flow control even in harsh saltwater environments. Its compliance with Japanese Industrial Standard (JIS) F7312 and pressure rating of 16K guarantees interchangeability and high performance in shipbuilding projects worldwide.
Our globe valve features a compact, durable body that minimizes pressure drop while providing excellent throttling and shut-off capabilities. With an annual export value exceeding US$1 million, Shanghai Zhibang has supplied these valves to diverse markets including North America, Europe, Southeast Asia, and the Middle East, earning trust through consistent quality and on-time delivery. We ship from major ports such as Shanghai, Guangzhou, Hong Kong, and Beijing, ensuring seamless logistics for global customers.
Product Features & Technical Specifications
- Marine-Grade Cast Steel Body: Made from high-strength cast steel with enhanced corrosion resistance, suitable for ballast water, seawater, and offshore hydrocarbon services.
- JIS F7312 Compliance: Adheres strictly to JIS B2071 / F7312 standard dimensions, face-to-face lengths, and flange drilling templates for direct replacement of OEM valves.
- 16K Pressure Rating: Rated for nominal pressure 16 bar (approx. 232 psi) at ambient temperature, providing reliable performance in medium-pressure systems.
- Precision Machined Seat & Disc: Stainless steel seat ring and disc ensure bubble-tight shut-off and extended service life. The disc design allows linear flow characteristics for accurate throttling.
- Low Operating Torque: The valve stem is equipped with a thrust washer and gland packing made of PTFE or graphite (optional), reducing friction and enabling smooth handwheel operation.
- Anti-Scald Stem Design: Backseat feature allows repacking under pressure when valve is fully open, minimizing downtime during maintenance.
- Multiple End Connections: Standard flanged ends per JIS B2220 (10K/16K drilling), with threaded or butt-weld ends available upon request for specialized installations.
- Wide Size Range: Available from DN15 (1/2") to DN300 (12") – custom sizes can be manufactured per customer drawing or specification.
- Optional Coating & Painting: Standard blue epoxy coating for corrosion protection; other colors (e.g., red, gray) and zinc-rich primer for offshore environment are optional.

Advantages for Shipbuilding & Offshore Applications
- Reliable Shut-Off in Ballast Systems: The globe valve design provides tight sealing against backpressure, preventing leakage of ballast water and protecting marine ecosystems.
- Resistance to Corrosive Media: Cast steel with optional stainless steel trim resists pitting and crevice corrosion from seawater, reducing maintenance intervals.
- Space-Saving Compact Design: Compared to gate valves, the globe valve offers shorter face-to-face length, helping optimize piping layout in confined engine rooms or offshore topsides.
- Easy Maintenance: The bolted bonnet and accessible seat rings allow quick replacement of internal parts without removing the entire valve from the pipeline.
- Compliance with International Standards: Meets JIS requirements common in Asian shipyards, and can be manufactured to other standards (e.g., ANSI, DIN) upon request.
- Versatile Options: Available with different packing materials (PTFE, graphite), gear operators, limit switches, or positioners for remote control – all customizable.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between JIS F7312 and other globe valve standards?
A: JIS F7312 is the Japanese Industrial Standard for marine globe valves, specifying dimensions, pressure ratings, and material requirements. It is commonly used in Asian shipbuilding and offshore platforms. The 16K rating corresponds to PN16 (16 bar) nominal pressure. -
Q: Can this valve be used for ballast water treatment systems?
A: Yes. The JIS F7312 globe valve is suitable for ballast water line applications. Its cast steel body and stainless steel trim provide good corrosion resistance to seawater, and the valve can be supplied with appropriate coatings for UV/chemical treatment environments. -
Q: Is the valve supplied with a handwheel or can I order a gearbox?
A: The standard configuration includes a handwheel for manual operation. Gearbox operators or pneumatic/electric actuators are available as optional add-ons. Please specify your requirement when ordering. -
Q: What flange drilling does the valve use?
A: Standard flanges are drilled according to JIS B2220 for 10K/16K pressure class. If you need ANSI 150/300 or DIN PN16 flanges, we can customize the flange facing and drilling pattern – please advise. -
Q: What test certifications do you provide?
A: Each valve is hydrostatically tested in accordance with JIS B2071 and API 598 (optional). A test certificate and material certificate (if required) are included. Our ISO9001 quality system ensures traceability. -
Q: Do you offer sizes larger than DN300?
A: DN350 and DN400 sizes can be manufactured on special order, subject to minimum order quantity. Contact our sales team for feasibility and lead time. -
Q: What is the typical delivery time for standard sizes?
A: For standard DN15–DN200 sizes without customization, delivery is approximately 15–20 working days. Larger or customized valves may take 25–35 days. We ship from Shanghai or nearby ports. -
Q: Can you paint the valve in a specific color to match my ship's piping?
A: Yes. While our standard color is marine blue, we can apply any RAL color or special paint system (e.g., epoxy, polyurethane) upon customer request. Please provide the coating specification.
