Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, is a professional manufacturer specializing in high-performance forged steel valves. With an annual export value of US$1-1.5 million and ISO9001 certification, we are dedicated to delivering reliable marine and offshore solutions. Our Forged Steel Marine Check Valve is specifically engineered for FPSO (Floating Production Storage and Offloading) units and other offshore applications, offering superior durability under extreme conditions. The valve covers sizes from DN15 to DN200 with pressure ratings from PN6.4 to 16MPa, and features flanged ends for easy installation. Every unit is designed to prevent backflow, ensuring system safety and operational efficiency in the harshest maritime environments.
Key Features & Technical Specifications
- Forged Steel Body: Made from high-quality forged steel (ASTM A105 or similar), providing exceptional strength, corrosion resistance, and long service life in saline and high-pressure environments.
- Marine-Grade Construction: Designed to meet the rigorous demands of FPSO and offshore platforms, including resistance to vibration, thermal shock, and cyclic loading.
- Swing Check Mechanism: The disc swings freely on a hinge, minimizing pressure drop and allowing smooth fluid flow while effectively preventing reverse flow.
- Flanged Ends: Standard flanged connections (ASME B16.5 or DIN) ensure secure and leak-proof integration with existing pipeline systems.
- Wide Size & Pressure Range: Available from DN15 to DN200, and pressure classes from PN6.4 (64 bar) up to PN16.0 (160 bar), covering a broad spectrum of offshore applications.
- Temperature Capability: Suitable for operating temperatures from -20°C to +400°C, with optional materials for higher or lower limits upon request.
- ISO9001 Quality Management: Produced under strict ISO9001 certified manufacturing processes, ensuring consistent quality and traceability.
- Customizable Options: Disc and seat materials (e.g., stainless steel, stellite), trim configurations, and coatings are available to match specific media and environmental conditions.

Q: What is the maximum operating temperature and pressure?
A: Our standard design handles temperatures from -20°C to +400°C and pressures up to PN16.0 (16 MPa). For higher temperatures or pressures, please contact our sales team for customized solutions. -
Q: Does the valve comply with FPSO offshore requirements?
A: Yes, this valve is designed for marine and offshore applications including FPSO. It meets relevant API, ISO, and ASME standards and can be supplied with NACE MR0175 compliance upon request. -
Q: What flanges standards are supported?
A: The valve is available with flanges per ASME B16.5 (150# to 900#) or DIN EN 1092-1 (PN6 to PN160). Other flange standards can be accommodated on request. -
Q: Do you provide testing certificates?
A: Absolutely. Each valve is hydrostatically tested per API 598 or ISO 5208. We can provide material certificates (EN 10204 3.1/3.2), NDT reports, and other required documentation. -
Q: What is the typical lead time?
A: For standard sizes (DN15 to DN200), lead time is 15–30 working days depending on quantity. Customized orders may require longer. We offer express shipping from Shanghai, Guangzhou, Hong Kong, or Beijing ports. -
Q: Can the valve be used for seawater service?
A: Yes, with suitable material selection. We recommend stainless steel disc and seat, and optional epoxy coating on the interior to enhance corrosion resistance in seawater. Please specify your application when ordering. -
