Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Marine High Temperature Globe Check Valve, engineered specifically for demanding offshore platform steam systems. As a trusted manufacturer since 2016 with an annual export value of US$1–1.5 million, we combine rigorous ISO9001 quality management with decades of industry expertise to deliver valves that withstand extreme conditions. This globe check valve is designed for 425℃ steam service, featuring a robust carbon steel body, DN150 flanged connections, and a pressure rating of PN6.4MPa. It offers reliable backflow prevention while minimizing pressure drop – a critical advantage for steam system efficiency and safety. Whether you operate in the North Sea, Gulf of Mexico, or Southeast Asia waters, our valve meets the highest standards of marine durability.
Key Features & Technical Specifications
- High Temperature Capability: Rated for continuous operation up to 425℃, suitable for superheated steam and high-temperature condensate.
- Globe Check Valve Design: Combines the throttling ability of a globe valve with automatic check function – ideal for steam systems where flow direction must be strictly controlled.
- Durable Carbon Steel Body: ASTM A216 WCB or equivalent carbon steel provides excellent mechanical strength and resistance to thermal fatigue in marine environments.
- Flanged Connections (DN150 / PN6.4MPa): Raised face or flat face flanges per ASME B16.5 or EN 1092-1, ensuring leak-proof sealing and easy installation on offshore piping systems.
- Low Pressure Drop: Streamlined flow path reduces energy loss, improving overall steam system efficiency.
- Corrosion Protection: Standard anti-corrosion coating (optional epoxy or zinc-rich primer) extends service life in salt-laden offshore atmospheres.
- ISO9001 Certified Manufacturing: Every valve undergoes strict quality control from raw material to final hydrostatic test.
- Customizable Options: Available with different trim materials (Stellite, 13Cr, etc.), bonnet types, and actuation accessories upon request.

Advantages for Offshore Steam Applications
- Enhanced System Reliability: Prevents reverse flow that could damage turbines or cause water hammer – essential for steam distribution on platforms.
- Space-Saving Design: The combined globe & check function eliminates the need for separate valves, reducing footprint and piping complexity.
- Long Service Life: Hardened seat and disc surfaces resist erosion from high-velocity steam, while carbon steel body withstands thermal cycling.
- Easy Maintenance: Bonnet design allows quick access to internal parts for inspection or seat replacement without removing the valve from the line.
- Global Compliance: Our valves are accepted in major markets including North America, Europe, Southeast Asia, and the Middle East, with shipping from Shanghai, Guangzhou, Hong Kong, or Beijing.

Frequently Asked Questions (FAQ)
-
Q: Can this valve be used for saturated steam as well as superheated steam?
A: Yes, it is suitable for both saturated and superheated steam up to 425℃. For steam with high moisture content, we recommend selecting a Stellite faced seat to resist droplet erosion. -
Q: What is the maximum allowable working pressure at 425℃?
A: The PN6.4MPa rating is typically for ambient temperature. At 425℃, the pressure rating must be derated according to ASME B16.34 or EN 12516-1. Please contact our engineering team for the exact derating curve for your specific material grade. -
Q: Are flanges supplied with gaskets and bolts?
A: The valve is delivered with flanges only. We can provide companion flanges, gaskets, and bolting as optional items. Please specify when ordering. -
Q: What trim materials are available for corrosive steam?
A: Standard trim is 13Cr stainless steel. For steam with low pH or chloride content, we offer Alloy 316 or Stellite 6 overlays. Custom trim materials can be discussed. -
Q: Can the valve be installed horizontally or vertically?
A: The globe check valve design allows installation in any orientation, though horizontal installation with the stem upward is typical for optimal disc movement. For vertical lines, ensure flow direction is upward. -
Q: Do you provide third-party inspection certificates?
A: Yes, we can arrange inspection by classification societies such as DNV, BV, ABS, or Lloyds at an additional cost. Our standard valves are tested per API 598 and come with a material certificate. -
Q: What is the typical lead time for DN150 PN6.4 valves?
A: For standard carbon steel valves, lead time is approximately 30-45 days from order confirmation. Urgent orders can be expedited within 20-30 days subject to material availability. -
Q: How do I request a quote for a different size or pressure class?
A: Please contact our sales team via email or phone with your required size, pressure, temperature, and quantity. We can customize the design for DN50–DN300 and PN1.6–PN10MPa.
