Marine Globe Check Valve Carbon Steel DN200 PN6.4MPa Flanged Rising Stem CCS Certified
Product Spotlights
Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our premium Marine Globe Check Valve – a high-performance stop-check valve designed specifically for demanding marine and offshore environments. Manufactured from durable Carbon Steel with a nominal diameter of DN200 and a pressure rating of PN6.4MPa (64 bar), this flanged rising stem valve is fully CCS certified, ensuring compliance with the strictest maritime standards. Since our establishment in 2016, we have focused on delivering reliable valve solutions to global clients, with annual exports exceeding US$1 million. Our factory in Shanghai employs advanced machining and rigorous testing procedures to guarantee long service life and leak‑tight performance. This globe check valve combines the functions of a globe valve (throttling/stop) and a check valve (automatic backflow prevention) in one compact unit, making it an ideal choice for piping systems where space and reliability are critical.
Key Features & Technical Advantages
- Dual Function Design – Acts as both a globe valve (for flow regulation and shut‑off) and a check valve (for automatic prevention of reverse flow), reducing the need for separate valve installations.
- Rising Stem with Visual Indicator – The rising stem provides a clear visual indication of the valve position (open/closed), allowing operators to easily monitor the valve status from a distance.
- Carbon Steel Construction – Robust carbon steel body and bonnet offer excellent mechanical strength and resistance to high pressure and temperature, suitable for marine water, oil, and gas systems.
- Flanged Connection (RF/FF) – Designed with flanged ends according to DIN/ANSI standards, ensuring secure and leak‑proof pipe integration. Gasket faces are available in raised face (RF) or flat face (FF) upon request.
- PN6.4MPa High Pressure Rating – Rated for nominal pressure up to 6.4 MPa (64 bar), this valve is engineered to withstand the high‑pressure demands of marine propulsion, ballast, and fire‑fighting systems.
- CCS Type Approval – Certified by China Classification Society (CCS), assuring that the valve meets international marine safety and performance standards. Additional ABS, DNV, or BV certifications are available upon request.
- Tight Shut‑Off & Low Pressure Drop – The metal‑to‑metal sealing seat design ensures minimal leakage (ISO 5208 Rate A) while the streamlined flow path reduces turbulence and pressure loss, saving energy.
- Easy Maintenance – The bonnet is bolted and the seat ring is replaceable, allowing for quick in‑situ repair without removing the entire valve from the pipeline.

Benefits for Your Marine System
- Space & Weight Savings – Combining two functions into one valve reduces the number of flanges and fittings, saving valuable space and weight on board.
- Enhanced Safety – The automatic check function prevents backflow that could cause pump damage or system contamination, while the globe shut‑off enables positive isolation during maintenance.
- Corrosion Resistance – Carbon steel body with internal stainless steel or Stellite trim resists corrosion from seawater and aggressive fluids, extending service life in marine atmospheres.
- Low Maintenance Cost – Replaceable seat and stem components allow simple overhaul without replacing the entire valve, reducing lifecycle costs.
- Global Compliance – CCS certification meets Chinese and many international maritime regulations; other classification society approvals can be provided for your specific project.

Frequently Asked Questions (FAQ)
-
What is the difference between a globe check valve and a regular check valve?
A globe check valve (stop‑check) can both regulate flow (like a globe valve) and automatically prevent backflow (like a check valve). A regular check valve only stops reverse flow and cannot be used for throttling or shut‑off. -
Is this valve suitable for seawater service?
Yes. The carbon steel body with stainless steel or Stellite trim provides good corrosion resistance in seawater. For highly corrosive environments, we recommend upgrading internal trim to SS316 or duplex stainless steel (optional). -
What does CCS certification mean?
CCS (China Classification Society) certification indicates that the valve design, materials, and testing meet the requirements for marine applications as defined by CCS rules. It is widely accepted for ships and offshore installations in China and many other countries. -
Can I get other certifications like ABS, DNV, or BV?
Absolutely. While our standard product is CCS certified, we can produce valves with ABS, DNV, GL, BV, or LR certificates upon request. Please specify your required classification society when ordering. -
What is the maximum operating temperature?
The standard carbon steel body with stainless steel trim can operate from -29°C to +425°C. For higher temperatures, special materials like alloy steel or high‑chrome steels are available. -
How is the valve operated? Is it automatic?
The globe check valve has a manual handwheel for the globe shut‑off function (rising stem). The check function is automatic – when forward flow stops or reverses, the disc closes automatically under spring or gravity action. -
What is the lead time for DN200 PN6.4MPa CCS valves?
For standard models, the lead time is approximately 30–45 days after order confirmation. Customized options (different trims, gear operators, or certifications) may require 45–60 days. -
Do you provide installation and maintenance manuals?
Yes, each valve comes with an operation & maintenance manual, including installation instructions, recommended torque values, and troubleshooting guidelines. We also offer technical support via email or phone.
