Shanghai Zhibang Valve Manufacture Co., Ltd. is a professional valve manufacturer established in 2016, with an annual export value of US$1 Million to US$1.5 Million. Located in Shanghai, China, we are ISO9001 certified and serve a global market including North America, South America, Europe, Asia, Africa, and Oceania. Our Cast Iron Globe Check Valve for Marine Use is specifically designed to meet the rigorous demands of marine applications. It combines reliable sealing, low flow resistance, and durability, backed by LR and ABS approvals. With sizes ranging from DN50 to DN200 and a pressure rating of PN16, this flanged-end valve ensures safe and efficient operation in ship systems, ballast water lines, and marine piping networks.
Key Features and Technical Specifications:
- Durable Cast Iron Body: Offers excellent corrosion resistance and mechanical strength in harsh marine environments.
- Globe Check Design: Combines globe valve throttling capability with check valve backflow prevention, ideal for systems requiring flow control and non-return protection.
- Flanged Ends (PN16): Standardized flange dimensions for easy installation and maintenance, compatible with international piping systems.
- Manual Actuation: Simple handwheel operation allows precise open/close and adjustment, requiring no external power.
- LR & ABS Approved: Certified for marine use, ensuring compliance with international maritime regulations.
- Size Range DN50 – DN200: Covers a wide range of pipe diameters for various marine applications.
- Pressure Rating PN16: Suitable for medium-pressure systems commonly found in marine environments.
- Low Pressure Drop: Optimized flow path minimizes energy loss during operation.
- Reliable Sealing: Metal-to-metal or optional soft-seat disc ensures tight shut-off even after repeated cycles.

Frequently Asked Questions:
Q1: What is the difference between a globe check valve and a standard check valve?
A: A globe check valve combines the functions of a globe valve (for throttling and shut-off) and a check valve (for preventing backflow). It uses a guided disc that can be manually controlled or allowed to move freely. This design provides better flow regulation and positive shut-off capability compared to a simple swing or lift check valve.
Q2: Can this valve be used in seawater systems?
A: Yes, the cast iron body is suitable for seawater when properly coated. We offer optional epoxy or nickel coating for enhanced corrosion resistance. Bronze or stainless steel trims are available for critical seawater applications.
Q3: Are the LR and ABS approvals fully transferable to my project?
A: Our valves are type-approved by Lloyd’s Register (LR) and American Bureau of Shipping (ABS). The approval covers the design, materials, and manufacturing process. For specific vessel incorporation, we can provide the relevant certificates and documentation as required by the classification society.
Q4: What are the standard flange drilling dimensions? Are they compatible with ANSI flanges?
A: This valve is designed with EN 1092-2 / PN16 flange drilling dimensions (ISO 7005-2). They are not directly interchangeable with ANSI Class 150 flanges. However, we can supply adapters or manufacture special flange configurations upon request. Please confirm your flange standard when ordering.
Q5: Is the valve bidirectional? Can flow direction be reversed?
A: A globe check valve is usually unidirectional. The flow direction is indicated by an arrow on the body. Installing in the reverse direction may cause the disc to obstruct flow or fail to seal. Always install with the arrow pointing in the intended flow direction.
Q6: What is the maximum operating temperature?
A: For standard cast iron construction, the temperature range is typically -10°C to 150°C (14°F to 302°F). For higher temperature applications, we recommend alternative materials such ductile iron or steel. Please consult our technical team for specific temperature requirements.
Q7: Do you offer a warranty?
A: Yes, we provide a 12-month warranty from the date of shipment against manufacturing defects. Extended warranty options are available upon negotiation.
Q8: How long is the lead time for LR ABS approved valves?
A: For standard sizes (DN50-DN200), our typical lead time is 15-25 working days after order confirmation. Larger quantities or special trims may require additional time. We can expedite orders when necessary.
