Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance Marine 316L Stainless Steel Globe Check Valve, designed specifically for demanding marine and offshore environments. Manufactured in our ISO 9001 certified facility since 2016, each valve combines premium 316L austenitic stainless steel construction with full DNV material traceability, ensuring the highest levels of corrosion resistance, reliability, and safety for critical seawater systems. With an annual export value exceeding US$1 million and a presence in major markets across North America, Europe, Asia, and Oceania, we deliver valves that meet the rigorous expectations of shipbuilders, offshore platform operators, and naval engineers worldwide.
Key Features & Technical Advantages
- 316L Stainless Steel Construction – Low carbon content (max 0.03%) prevents carbide precipitation during welding; excellent resistance to pitting and crevice corrosion in chloride-rich marine atmospheres.
- Globe Check Valve Design – Combines the linear flow regulation of a globe valve with the automatic backflow prevention of a check valve. Ideal for applications where both throttling and non-return functionality are required.
- DNV Material Traceability – Every component (body, bonnet, disc, seat) is supplied with certified mill test reports and traceable markings, fully compliant with Det Norske Veritas (DNV) requirements for marine classification.
- 1-Year Warranty – Backed by comprehensive manufacturer coverage, giving you peace of mind for your offshore or shipboard installation.
- Multiple End Connections – Available in flanged (ANSI/DIN), threaded (NPT/BSPT), and socket weld configurations. Custom connection styles can be produced upon request.
- Proven Leakage Performance – Metal-to-metal or optional soft seal (PEEK/PTFE) ensures zero leakage in the reverse direction, tested to API 598 / ISO 5208 standards.
- Low Pressure Drop – Streamlined flow path reduces turbulence and minimizes head loss, contributing to energy efficiency in pumping systems.
- Full Traceability – Each valve is serialized and linked to a complete manufacturing record, including heat numbers, hydrostatic test results, and dimensional inspection data.

Benefits to Your Marine System
- Extended Service Life – 316L’s resistance to seawater corrosion and erosion dramatically reduces maintenance intervals compared to cast iron or carbon steel valves.
- Classification Compliance – DNV material traceability simplifies class society inspections (DNV, Lloyd’s, ABS, BV) and ensures your vessel or platform meets regulatory requirements.
- Space & Weight Savings – The integrated globe-check function eliminates the need for separate stop and non-return valves, reducing piping complexity and overall weight.
- Reliable Backflow Prevention – The guided disc design ensures positive shut-off even under low differential pressure, preventing water hammer and potential system damage.
- Global Availability – We ship from Shanghai, Guangzhou, Hong Kong, and Beijing with short lead times. Our logistics network covers North America, South America, Europe, Africa, Oceania, and Asia.

Frequently Asked Questions (FAQ)
-
Q: What does DNV material traceability mean exactly?
A: It means that each raw material batch used to produce the valve is documented with mill certificates, heat numbers, and chemical composition reports, all verified according to DNV rules. This allows classification societies to trace the origin and properties of every component. -
Q: Can this globe check valve be used for throttling / regulation?
A: Yes, the globe-style design allows for flow regulation by positioning the disc. However, for continuous throttling service, we recommend consulting our engineers to select the appropriate trim material and ensure long-term performance. -
Q: What end connections are available?
A: We offer flanged (ANSI B16.5, DIN EN 1092-1), threaded (NPT, BSPT), and socket weld (ASME B16.11). Other custom connections are available upon request. -
Q: Is the valve suitable for high-pressure steam applications?
A: While 316L offers good performance, the temperature limit for soft seat materials may restrict steam use. For steam service above 180°C, we recommend our metal-seated version. Please specify your operating conditions. -
Q: How long is the lead time for a typical order?
A: For standard sizes (NPS 2"–6") and Class 150, our lead time is 3–4 weeks. Customized valves or non-standard materials may require 5–8 weeks. We also maintain limited stock for urgent needs. -
Q: Do you provide third-party inspection certificates?
A: Yes, we can arrange inspection by DNV, Lloyd’s, ABS, or other agencies at the customer’s request. All test reports are included with the shipment. -
Q: What warranty coverage is included?
A: We provide a 1-year warranty covering defects in material and workmanship. Extended warranty options can be negotiated for large projects. -
Q: Can I get samples or small quantities for testing?
A: Absolutely. We can produce sample valves for evaluation. Please contact our sales team to arrange a trial order with reasonable lead time.
