Shanghai Zhibang Valve Manufacture Co., Ltd. has been a dedicated manufacturer of high-quality industrial valves since 2016. Leveraging our extensive experience in the marine and industrial sectors, we proudly present the PN2.5MPa DN150 Carbon Steel Globe Check Valve for Marine Flanged Rising Stem CCS. This valve is meticulously engineered to meet the rigorous demands of marine applications, combining the functions of a globe valve and a check valve into one robust unit. It is designed to provide reliable flow control and automatic backflow prevention, ensuring safety and efficiency in shipboard piping systems. With a focus on durability and performance, our valve is manufactured under strict quality control and holds the prestigious CCS (China Classification Society) certification, making it a trusted choice for shipbuilders and marine engineers worldwide.
Key Features & Technical Specifications
- Dual Function Design: Integrates globe valve shut-off capability with check valve automatic backflow prevention, reducing installation space and cost.
- Robust Carbon Steel Body: Constructed from high-strength carbon steel (WCB), offering excellent corrosion resistance and mechanical strength for marine environments.
- Rising Stem with Visual Indicator: The rising stem provides a clear visual indication of valve position (open/closed), facilitating easy operation and maintenance.
- Flanged Connection: Conforms to standard marine flanging (RF/FF) for secure, leak-proof installation in pipeline systems.
- PN2.5MPa (250 bar) Pressure Rating: Capable of withstanding high-pressure marine systems, ensuring reliable performance under extreme conditions.
- DN150 (6-inch) Bore: Designed for medium to large flow applications commonly found in shipboard water, oil, and gas systems.
- Certified Quality: Holds CCS approval, meeting rigorous international marine standards. Our manufacturing facility is ISO9001 certified, ensuring consistent product quality.
- Easy Maintenance: The rising stem and bonnet design allow for quick inspection and replacement of internal components without removing the valve from the pipeline.

Detailed Advantages for Your Marine Systems
Our globe check valve offers significant benefits over traditional separate valves. By combining two functions, it reduces the number of potential leak points and simplifies pipeline layout. The rising stem feature allows operators to quickly confirm valve status, enhancing safety during critical operations. The carbon steel body is specifically treated to resist seawater corrosion and withstand high-pressure surges common in marine environments. Additionally, the flanged design ensures easy installation and compatibility with existing shipboard piping standards (such as JIS, DIN, or ANSI upon request).
Technical features include: positive sealing at rated pressure, low operating torque, and a streamlined flow path that minimizes pressure drop. The check function utilizes a spring-assisted disc that responds rapidly to flow changes, preventing water hammer and protecting downstream equipment. The entire assembly is manufactured with tight tolerances and tested per applicable standards to guarantee leak-free performance.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a globe check valve and a standard check valve?
A: A globe check valve combines a globe valve's shut-off capability with a check valve's automatic backflow prevention. It can be manually closed to stop flow completely, while also automatically preventing reverse flow when open. This dual function saves space and cost compared to installing two separate valves. -
Q: Does this valve meet CCS certification? Can you provide the certificate?
A: Yes, this valve is designed and manufactured to meet CCS (China Classification Society) requirements. We can provide the relevant certificate upon request as part of the documentation package. -
Q: What flanging standards does the valve comply with?
A: The valve is designed with raised face (RF) or flat face (FF) flanges per GB/T standard, but can be customized to meet other standards such as ANSI, DIN, or JIS. Please specify your requirement when ordering. -
Q: Can the valve be used for seawater or other corrosive media?
A: The standard carbon steel body is suitable for fresh water, oil, and certain gases. For seawater or highly corrosive media, we recommend optional stainless steel trim or a fully stainless steel body; please contact our sales team for a tailored solution. -
Q: What is the maximum operating temperature?
A: For carbon steel (WCB), the typical operating temperature range is -29°C to +425°C. For higher temperature applications, we can provide alternative materials like alloy steel. -
Q: How is the valve tested before shipment?
A: Each valve undergoes hydrostatic shell test and seat leakage test according to ISO and CCS standards. A test report is included with the shipment. -
Q: Do you offer spare parts or replacement seats/discs?
A: Yes, we provide spare parts packages and can support maintenance needs. The rising stem design allows easy access to internal components without removing the valve from the line. -
Q: What is the lead time for this valve?
A: Typical lead time is 15–30 days depending on quantity and customization. We have stock available for standard configurations; please check with our sales team for current availability.
