Shanghai Zhibang Valve Manufacture Co., Ltd (established in 2016) is a professional manufacturer specializing in high-quality industrial valves. Our annual export value reaches US$1–1.5 million, serving markets across North America, South America, Europe, Asia, Africa, and Oceania. With ISO9001 certification and strict quality control, we are proud to present the JIS F7312 Forged Steel Globe Valve – a reliable solution for critical flow control applications. This valve combines robust forging technology, compliance with Japanese Industrial Standards (JIS), and international certifications including BV (Bureau Veritas) and RINA (Registro Italiano Navale). Each unit comes with a 1-year warranty and a Mill Test Report (MTR) available upon request, ensuring full traceability and peace of mind for marine, industrial, and energy sectors.
Designed for demanding environments, the JIS F7312 globe valve features a forged steel body that delivers superior strength and leak-resistant performance. Its disc and seat are precision machined to provide a tight shut‑off, minimizing internal leakage. The valve can be supplied in butt weld, socket weld, or threaded end connections to suit various piping systems. Available in sizes from DN15 to DN80 (1/2″ to 3″) and pressure ratings from Class 150 to Class 2500, it accommodates a wide range of operating conditions. Below are key technical specifications:
| Parameter | Value |
| Standard | JIS B2071 / F7312 |
| Body Material | Forged Carbon Steel (A105) / Alloy Steel (F22, F11) |
| Disc Material | 13Cr / F304 / F316 |
| Stem Material | Stainless Steel 13Cr / 304 / 316 |
| Pressure Rating | Class 150, 300, 600, 800, 1500, 2500 (PN10–PN420) |
| Size Range | DN15 – DN80 (1/2″ – 3″) |
| End Connection | Butt Weld / Socket Weld / Threaded (BSP, NPT) |
| Working Temperature | -29°C to +425°C |
| Body & Seat Hardness | Stellite or hard alloy facing on request |
| Valve Operation | Handwheel (standard), Gear/Actuator (optional) |
Product Features & Advantages:
- Forged Body Strength: The hot forging process eliminates internal voids and ensures a homogeneous grain structure, resulting in higher tensile strength and resistance to pressure surges.
- BV & RINA Certified: Both certifications guarantee that the valve meets stringent international quality and safety standards, specifically required for maritime and offshore applications.
- 1‑Year Warranty & MTR: Every valve is backed by a 12‑month warranty. A Mill Test Report (chemical composition and mechanical properties) is supplied per request, offering full material traceability.
- Leak‑Tight Design: The disc and seat undergo precision lapping and hard overlay (Stellite optional) to achieve bubble‑tight shut‑off, minimizing fugitive emissions.
- Multiple End Connections: Choose butt weld, socket weld, or threaded ends to match your piping code – flexibility to fit both new installations and retrofits.
- High Temperature Capability: With proper material selection, the valve can withstand steam and thermal oil applications up to 425°C.
- Easy Maintenance: The bolted bonnet design allows quick access to internal parts, reducing downtime during inspection or repair.
Customer Benefits:
- Reduced Lifecycle Cost: Durable forged construction and hard‑faced seat minimize wear, extending service intervals.
- Enhanced Safety: BV and RINA approvals ensure the valve complies with classification society rules for critical systems like fire‑fighting, fuel oil, and cooling water on ships and platforms.
- Global Compliance: In addition to JIS, the valve can be manufactured according to ASME or EN standards upon request, making it suitable for international projects.
- Reliable Supply: As a manufacturer with ISO9001 quality system, we guarantee consistent product quality and on‑time delivery from our Shanghai plant (port of shipment: Shanghai, Guangzhou, Hong Kong, Beijing).
