Shanghai Zhibang Valve Manufacture Co., Ltd., a manufacturer established in 2016 with ISO9001 certification and an annual export value of US$1–1.5 million, proudly presents the JIS F7312 16K Cast Steel Globe Valve. Designed specifically for steam service and chemical plant pipeline control, this valve reliably handles temperatures up to 425°C. Our engineering team ensures every valve meets rigorous quality standards, making it a trusted choice for critical industrial applications across global markets including North America, Europe, Southeast Asia, and the Middle East.
The JIS F7312 globe valve is built from high-strength cast steel, offering exceptional durability and corrosion resistance in harsh steam and chemical environments. With a 16K pressure rating and flanged ends conforming to JIS standards, it provides a secure, leak-tight connection in your piping system. Whether you are controlling steam flow in power plants or regulating chemicals in processing lines, this valve delivers precise throttling and positive shut-off.
Key Features & Technical Specifications
- Material: Premium cast steel (ASTM A216 WCB equivalent) – strong, heat-resistant, and suitable for high-temperature steam.
- Pressure Rating: 16K (JIS standard, ~16 bar / 230 psi at ambient temperature) – derated for steam service as per JIS B2071.
- Temperature Range: -10°C to 425°C – tested and certified for continuous steam operation up to max temperature.
- Design Standard: JIS F7312 – ensures interchangeability and compliance with Japanese industrial norms.
- End Connection: Flanged (JIS 10K/16K compatible) – easy installation with standard bolting patterns.
- Operation: Rising stem with handwheel – clear visual indication of valve position; manual override for reliable local control.
- Seat & Disc: Hardened stainless steel seat ring and disc – wear-resistant, maintaining tight shut-off after repeated cycles.
- Packing: Graphite-based – low fugitive emissions, suitable for steam and high-temperature applications.

Why choose the JIS F7312 Cast Steel Globe Valve for your plant? This valve is engineered to withstand the demanding conditions of steam service in chemical plants. The cast steel body offers excellent mechanical strength, while the internal trim materials are selected for erosion resistance. The rising stem design provides operators with a quick visual status check, reducing the risk of misoperation. Compared to gate valves, globe valves offer better throttling control and a tighter seal, essential for isolation and flow modulation in steam systems.
Each valve undergoes hydrostatic shell and seat tests to ensure zero leaks. Our ISO9001-certified quality management system guarantees traceability and consistent manufacturing. Whether you need a standard size or a custom configuration (e.g., gearbox operation, locking device, special coatings), we can accommodate.
