Shanghai Zhibang Valve Manufacture Co., Ltd., a professional manufacturer established in 2016, proudly presents our Cast Marine Bronze Globe Check Valve designed for reliable non-return flow control in demanding marine and industrial environments. With an annual export value of US$1–1.5 million, our valves are trusted by clients across North America, Europe, Southeast Asia, and beyond. Crafted from high-grade marine bronze, this check valve offers exceptional corrosion resistance, durability, and tight sealing performance across sizes DN15 to DN50 and pressure ratings PN1.0 to PN2.5 MPa, with both threaded and flanged end options for versatile installation. Whether you need a robust solution for shipbuilding, offshore platforms, or water treatment systems, our globe check valve delivers consistent, maintenance-friendly operation.
Key Features & Technical Specifications
- Superior Material: Cast marine bronze (copper alloy) ensures excellent resistance to seawater corrosion, biofouling, and harsh chemicals, extending service life.
- Globe Check Design: Combines the functions of a globe valve (throttling) and a check valve (non-return) in one compact body – ideal for systems requiring flow regulation and backflow prevention.
- Pressure Rating: Suitable for PN1.0, PN1.6, and PN2.5 MPa (Class 150 available on request), covering low to medium pressure applications.
- Size Range: DN15 (1/2") to DN50 (2") – covers common pipe diameters for marine and industrial piping.
- End Connections: Available in threaded (BSP, NPT) and flanged (DIN, ANSI, JIS) configurations to match existing pipelines without adapter costs.
- Reliable Sealing: Metal-to-metal or optional soft seat provides bubble-tight shut-off and prevents backflow even under low pressure differentials.
- Low Operating Torque: Optimized disc and seat geometry reduces handwheel effort, making manual operation smooth and easy.
- Certified Quality: Manufactured under ISO9001 quality management system, ensuring consistent product performance and traceability.

Customer Benefits & Application Advantages
- Extended Service Life: Marine bronze naturally resists dezincification and pitting, reducing replacement frequency in seawater systems.
- Space & Cost Savings: Dual function (globe + check) eliminates the need for two separate valves, saving installation space and procurement costs.
- Easy Maintenance: The globe check design allows inline inspection and seat replacement without removing the valve body from the pipeline.
- Versatile Installation: Threaded ends are ideal for small-bore systems, while flanged ends suit larger pipes or high-vibration environments.
- Global Acceptance: Our valves are exported worldwide – with ports in Shanghai, Guangzhou, Hong Kong, and Beijing – ensuring fast delivery and competitive freight.

Frequently Asked Questions (FAQ)
-
Q: Can this valve be used for both throttling and check function simultaneously?
A: Yes, the globe check design allows you to manually set the disc position for flow regulation while it automatically closes against backflow. However, prolonged throttling at very low openings may accelerate seat wear – consult our technical team for your specific duty cycle. -
Q: What is the difference between threaded and flanged versions?
A: Threaded ends (BSP or NPT) are easier and quicker to install on small pipes, while flanged ends provide stronger, leak-resistant connections for larger sizes or high-pressure systems. Both are available from stock. -
Q: What is the maximum working pressure for DN50 size?
A: For DN50, the maximum rating is PN2.5 MPa (approx. 362 psi). If you require higher pressure, we can offer custom designs – please contact our sales team. -
Q: Is the valve suitable for horizontal and vertical pipelines?
A: Yes, the globe check valve can be installed in both horizontal and vertical orientations (flow direction upward recommended for vertical lines). For downward flow, a spring-assisted closure option is available. -
Q: Do you provide test certificates and material certificates?
A: Yes, we can issue ISO9001 quality certificates, material test reports (MTR), and pressure test records upon request. Additional third-party inspection (e.g., by BV, DNV) is also available at an extra cost. -
Q: What is the lead time for standard sizes?
A: For orders of DN15–DN50 with standard end connections, typical lead time is 15–25 working days. Expedited delivery can be arranged for urgent projects. -
Q: Can I get a sample before bulk order?
A: Yes, we offer sample orders. The sample cost and shipping fee are negotiable, and we will refund the sample fee after bulk order confirmation (minimum quantity required). -
Q: How do I choose the correct valve for seawater application?
A: Our cast marine bronze is specifically designed for seawater. Ensure the pressure rating and end connections match your system. For highly corrosive media or extreme temperatures, we recommend consulting our engineering team for the best trim material (e.g., stainless steel disc).
