As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd has been dedicated to producing high-performance industrial valves since 2016. Our JIS F7312 Globe Valve is specifically engineered for demanding offshore oil transfer and marine engine applications. With a robust cast steel body and sizes ranging from DN80 to DN200, this valve delivers reliable shut-off and flow regulation under harsh marine conditions. We take pride in offering a product that combines Japanese industrial standards with our precision manufacturing expertise, ensuring long service life and operational safety.
This globe valve is designed to withstand high pressures and temperatures commonly encountered in offshore platforms, tanker loading systems, and marine engine cooling or fuel lines. The cast steel body provides excellent mechanical strength and corrosion resistance, while the flanged connections (RF/FF) ensure leak-tight joints. Available with handwheel or gearbox operation, it offers flexible control for both manual and automated systems. Every valve undergoes rigorous testing to meet JIS F7312 specifications, making it a trusted choice for shipbuilders, oil & gas operators, and marine engineering contractors worldwide.

Frequently Asked Questions (FAQ)
-
Is this valve suitable for seawater applications?
Yes, the cast steel body with proper coating and stainless steel internals can be used for seawater, but we recommend optional nickel-aluminum bronze or duplex stainless steel trims for enhanced corrosion resistance. -
What pressure ratings are available?
Standard options include 10K and 20K per JIS. We can also manufacture to other pressure classes upon request (e.g., 5K, 30K). Please specify your system requirements. -
Can I get a gearbox or electric actuator instead of a handwheel?
Absolutely. Gearbox operation is available for larger sizes or high-pressure applications. Electric, pneumatic, or hydraulic actuators can also be mounted upon request. -
What is the lead time for standard sizes?
For DN80-DN150 with handwheel, typical lead time is 15-25 working days. Custom variants may take 30-45 days. We can expedite for urgent orders. -
Do you provide a test certificate?
Yes, each valve comes with a material certificate and a hydrostatic/pneumatic test report. Third-party inspection (e.g., Lloyds, DNV) is available at extra cost. -
Is the valve compatible with JIS B2220 flanges?
Yes, our flanges conform to JIS B2220 (RF/FF). If you need ANSI or DIN flanges, we can adapt the design. -
What is the warranty period?
We offer a 12-month warranty from the date of shipment against manufacturing defects. Extended warranty is negotiable. -
Can you provide a sample for testing?
Certainly! Sample orders are welcome. We can produce a single unit for qualification testing; please contact our sales team for details.
