Shanghai Zhibang Valve Manufacture Co., Ltd. has been a reliable manufacturer of industrial valves since 2016, exporting high-quality products to over 10 countries worldwide. Our JIS 5K/10K/16K Marine Globe Valve is engineered for demanding marine and high-pressure applications, combining forged steel strength with socket weld connections for leak-proof performance. With ISO9001 certification and annual exports exceeding US$1 million, we deliver consistent quality and on-time delivery from our Shanghai facility.
This globe valve series is designed to meet JIS standards (5K, 10K, 16K pressure ratings) and features forged steel body and bonnet for superior mechanical properties. The socket weld ends provide a permanent, leak-free joint ideal for high-pressure piping systems. Whether used in marine seawater lines, steam systems, or hydraulic controls, these valves offer precise throttling and positive shut-off with a durable stainless steel trim.
Key structural highlights include fully guided disc for reduced vibration, renewable seat rings for extended service life, and a backseat design that allows packing replacement under pressure. The valves are supplied with either handwheel or gearbox operation, and can be customized with various trims (PTFE, Stellite) to suit specific media and temperatures.
Product Features & Benefits
- Forged Steel Body: High strength and impact resistance, ideal for high-pressure and high-temperature services.
- Socket Weld Ends: Eliminate potential leak paths; recommended for critical applications like marine and petrochemical.
- JIS Pressure Ratings: Available in 5K, 10K, and 16K classes to match system requirements.
- Stainless Steel Trim: Standard 13Cr or optional 304/316 SS for corrosion resistance in seawater.
- Rising Stem & Handwheel: Clear visual position indication and easy manual operation.
- Backseat Design: Allows stem packing replacement under full line pressure, minimizing downtime.
- Compact & Lightweight: Forged steel construction reduces weight compared to cast equivalents.
- OEM Support: Custom sizes, materials, and certifications available upon request.
