Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, is a reliable manufacturer specializing in industrial valves for marine and general industries. Our Marine Carbon Steel Globe Check Valve (DN15–DN200, PN1.6–6.4MPa, Flanged, Rising Stem) is engineered to deliver superior performance in demanding marine environments. With an annual export value of US$1–1.5 million and ISO9001 certification, we ensure every valve meets rigorous quality standards. This product combines the functions of a globe valve and a check valve, offering precise flow control and automatic backflow prevention in one compact design.
The valve body is made of high-quality carbon steel, suitable for seawater, steam, oil, and gas applications onboard ships and offshore platforms. The flanged connection allows easy installation and maintenance, while the rising stem provides clear visual indication of the valve position. Rated from PN1.6 to PN6.4, it can handle medium to high pressure systems with reliability. Available in sizes from DN15 to DN200, it covers a wide range of piping requirements.
Key Features & Technical Specifications
- Dual Functionality: Combines globe valve throttling capability with check valve automatic shut-off, reducing the need for additional components.
- Rising Stem Design: Stem moves upward when opened, providing clear visual position indication and easy manual operation.
- Flanged Connection: Conforms to standard flange dimensions (PN16/PN40/PN64), ensuring compatibility with existing piping systems.
- Material Durability: Carbon steel body with optional anti-corrosion coating extends service life in marine atmospheres.
- Temperature Range: Standard -20°C to +120°C; custom ranges available upon request.
- Testing & Quality: Every valve undergoes hydrostatic shell and seat tests per ISO5208 standards, ensuring zero leakage.

Frequently Asked Questions
-
Q: What is the difference between a globe check valve and a regular check valve?
A: A globe check valve combines the functions of a globe valve (throttling/regulating flow) and a check valve (preventing reverse flow). It can be manually operated to control flow rate and automatically closes when flow reverses. -
Q: Can this valve be used for seawater applications?
A: Yes, the carbon steel body with appropriate anti-corrosion coating is suitable for seawater. For highly corrosive environments, we recommend optional epoxy coating or stainless steel trim. -
Q: What pressure tests are performed before shipment?
A: Each valve undergoes hydrostatic shell test at 1.5 times the rated pressure and seat leakage test at 1.1 times rated pressure, in accordance with ISO5208. -
Q: Is the rising stem available in non-rising stem version?
A: The standard design is rising stem for clear position indication. Non-rising stem can be manufactured as a custom option upon request. -
Q: What flange standard do these valves comply with?
A: They comply with PN16/PN40/PN64 flanges per DIN or equivalent EN standard. We can also produce to ANSI 150/300/600 classes if needed. -
Q: Do you provide valves with CCS or other classification certificates?
A: While the product is designed for marine use and can be manufactured to meet CCS or other society requirements, please inquire for specific certification needs. Our ISO9001 system ensures traceability. -
Q: What is the lead time for standard sizes?
A: For DN15-DN200 standard pressure ratings, lead time is typically 15-25 working days after order confirmation, depending on quantity. -
Q: Can I get a sample for testing before bulk order?
A: Yes, samples are available. Please contact our sales team to arrange sample delivery and discuss terms.
