brand Shanghai Zhibang Valve

At Shanghai Zhibang Valve Manufacture Co., Ltd., we take pride in delivering high-performance valve solutions tailored for demanding marine and industrial environments. Our 316L Marine Globe Check Valve in sizes DN50 to DN150, with pressure ratings PN25 to PN40, is engineered to provide reliable, non-return flow control in seawater, oil, gas, and corrosive fluid systems. Combining a full-bore design with flanged ends and full compliance with international standards, this valve offers minimal pressure drop, robust sealing, and extended service life — a trusted choice for shipbuilding, offshore platforms, and process industries.

Key Features & Technical Specifications

High-Quality 316L Stainless Steel Construction – Excellent resistance to chloride corrosion, pitting, and crevice corrosion, ideal for marine and chemical applications.
Full Bore (Full Port) Design – Eliminates flow restrictions, reduces pressure loss, and allows easy pigging or cleaning.
Globe Check Valve Configuration – Provides positive backflow prevention with a guided disc that ensures smooth operation and tight shut-off.
Flanged Ends (ASME/EN/DIN) – Easy installation and maintenance, suitable for standard piping systems.
Pressure Rating PN25 to PN40 – Capable of handling medium to high pressure systems (approx. 25-40 bar at ambient temperature).
Size Range DN50 – DN150 (2" – 6") – Covers a wide range of pipeline diameters for typical marine and industrial applications.
Standard Compliant – Manufactured to recognized international standards (e.g., API, ASME, DIN), ensuring interchangeability and reliability.
Optional Trim Materials – Seat and disc materials can be customized (e.g., PTFE, Nitrile, Viton) upon request to suit specific media.

*Dimensions may vary depending on flange standard (ASME B16.5 / EN 1092-1). Contact us for detailed drawings.

Performance & Application Advantages

Corrosion Resistance – 316L material withstands seawater, acidic fluids, and high-chloride environments, reducing maintenance frequency.
Low Pressure Drop – Full bore design minimizes turbulence, saving energy in pumps and compressors.
Reliable Backflow Prevention – Globe-style disc ensures positive sealing even under low differential pressure.
Easy Maintenance – Bolted bonnet design allows quick inspection and replacement of internal trim without removing the valve from the pipeline.
Wide Application Range – Suitable for marine ballast systems, cooling water lines, oil transfer, chemical processing, and water treatment.
Temperature Range – Typically -20°C to +200°C (depending on seat material), with options for higher or lower temperatures on request.
Customization Available – Different flange facings, drilling patterns, and testing requirements can be accommodated to meet project specifications.

Frequently Asked Questions (FAQ)

Q: What is the difference between a globe check valve and a swing check valve?
A: A globe check valve uses a guided disc that moves vertically within the valve body, providing a more compact design and tighter shut-off even at low pressures. Swing check valves rely on a hinged disc, which can cause slamming. Globe check valves are preferred for dirty fluids or where low pressure drop is desired.
Q: Can this valve be used for steam service?
A: The standard disc and seat materials are 316L metal-to-metal, suitable for high-temperature media up to ~400°C. However, for superheated steam or specific conditions, we recommend a soft seat (e.g., PTFE) with proper pressure/temperature derating. Please consult our technical team.
Q: Are flanges supplied with gaskets and bolts?
A: The basic valve includes the flanged ends; gaskets and bolts are not included as standard. We can provide them as optional accessories upon request.
Q: What testing is performed before shipment?
A: Each valve undergoes hydrostatic shell test (1.5 x rated pressure) and seat leakage test (1.1 x rated pressure) in accordance with API 598 or similar standards. A test certificate is provided.
Q: Can you customize the flange drilling pattern to match existing pipes?
A: Yes, we offer flexible flange designs (ASME 150/300, PN16/25/40, JIS, etc.). Please provide your flange standard and drilling details for customization.
Q: What is the expected service life of this valve?
A: With proper installation and regular maintenance (e.g., seat and disc replacement), a 316L globe check valve can last 10-15 years in typical marine water systems. Actual life depends on media corrosivity and operating conditions.
Q: Do you offer OEM/private labeling?
A: Yes, we can manufacture valves with your brand, logo, and packaging. Minimum order quantities apply. Contact our sales team for details.
Q: What is your typical lead time for standard sizes?
A: For DN50-DN150 PN25/40, stock items can be shipped within 7-15 days after order confirmation. Custom sizes or special materials require 20-35 days.
