As a professional manufacturer of high-quality flow control products, Shanghai Zhibang Valve Manufacture Co., Ltd brings you the Forged Steel Globe Valve JIS F7312 3000Psi Threaded End DN20 – a precision-engineered component designed specifically for the demanding marine and shipbuilding industries. Our valves are manufactured under strict ISO9001 quality management systems, ensuring consistent performance and reliability. With years of experience in exporting to global markets including North America, Europe, and Southeast Asia, we understand the rigorous standards required by shipyards and marine engineers. This globe valve combines robust forged steel construction with the trusted JIS F7312 marine standard, making it an ideal choice for high-pressure steam, water, oil, and gas services aboard vessels.
Key Features & Technical Specifications
- Material Excellence: The valve body, bonnet, and disc are made from forged carbon steel (ASTM A105) or optional stainless steel 304/316, providing excellent strength and corrosion resistance in marine environments.
- Pressure Rating: Designed for 3000 Psi (Class 1500 equivalent) at ambient temperature, suitable for high-pressure applications such as boiler feed, fuel oil, and hydraulic systems.
- Threaded Ends: Standard NPT threads (1/2” to 2” available) allow easy installation without welding, reducing downtime and maintenance costs. The DN20 (3/4”) size is widely used for auxiliary lines on ships.
- JIS F7312 Compliance: Meets the Japanese Industrial Standard for marine valves, recognized globally for its strict dimensional and testing requirements. This ensures interchangeability with other JIS F7312 components.
- Disc Design: The globe valve features a metal-to-metal seat (optional PTFE or stellite faced) for tight shut-off and reliable sealing under high pressure. The rising stem design provides visual position indication.
- Temperature Range: Standard design handles temperatures from -20°C to +350°C; extended ranges available upon request.
- Testing & Certifications: Every valve undergoes hydrostatic shell test (1.5x rated pressure) and seat leakage test according to JIS B2003. ISO9001 factory certification guarantees traceability.

Benefits for Your Marine Applications
- Enhanced Safety: The forged steel construction ensures no porosity or internal defects, reducing the risk of catastrophic failure in critical ship systems.
- Long Service Life: Threaded ends eliminate welding stress, and the corrosion-resistant treatment (zinc phosphate or epoxy coating) extends valve life in saltwater environments.
- Easy Maintenance: The bolted bonnet design allows quick internal inspection and seat replacement without removing the valve from the pipeline.
- Global Compatibility: JIS F7312 dimensions allow direct replacement of existing valves in Japanese-designed ships and are compatible with many international piping systems.
- Cost-Effective: Forged steel offers superior strength-to-weight ratio compared to cast steel, reducing shipping costs and supporting structural weight.

Frequently Asked Questions
-
Q: Can this valve be used for high-temperature steam applications?
A: Yes, the standard design operates up to 350°C. For steam service above 350°C, we recommend specifying a stainless steel or super-alloy seat. Please contact us for tailored solutions. -
Q: What is the difference between this JIS F7312 valve and other globe valve standards?
A: JIS F7312 is a specific Japanese marine standard that defines precise face-to-face dimensions, flange thickness, and testing procedures. It ensures interchangeability with other JIS F7312 valves, which is critical when retrofitting in existing ship systems. -
Q: Do you provide a test certificate or material test report?
A: Absolutely. Each valve comes with a factory hydrostatic test certificate. A material test report (MTR) and third-party inspection certificate are available upon request. -
Q: What thread types are available besides NPT?
A: While NPT is standard, we can supply BSPT, BSPP, or JIS tapered threads on request. Please specify when ordering. -
Q: Is the handwheel removable or lockable?
A: The standard handwheel is fixed. For applications requiring locking, a lockable handwheel or a gearbox with locking mechanism can be added as an option. -
Q: What is the typical lead time for this valve?
A: For standard DN20 size with carbon steel, lead time is 15-25 days. Custom materials or special thread forms may require 30-45 days. We can expedite for urgent orders. -
Q: How do you handle corrosion protection for marine environment?
A: All valves receive a zinc phosphate primer plus an epoxy topcoat suitable for marine conditions. Stainless steel models offer additional corrosion resistance. We also offer hot-dip galvanized finish as a cost-effective option. -
Q: Can I get a sample order before bulk purchase?
A: Yes, sample orders are welcome. We offer competitive pricing for samples and can provide full product documentation and shipping via courier (DHL, FedEx, etc.) at your expense.
