Shanghai Zhibang Valve Manufacture Co., Ltd. presents our premium DN15-DN50 Marine Bronze Globe Check Valve, designed for reliable performance in demanding marine environments. With over 8 years of specialized valve manufacturing experience, we have perfected a product that combines the dual functions of a globe valve and a check valve in one compact unit. Rated for PN1.0-2.5MPa and available with both threaded and flanged connections, this valve is BV certified for shipbuilding and offshore applications. Our bronze alloy construction ensures excellent corrosion resistance against seawater, while the precision-machined disc and seat provide drip-tight sealing and long service life.
Engineered to meet the rigorous standards of the marine industry, this globe check valve offers superior flow control and backflow prevention. Whether you need a valve for ballast systems, cooling water lines, fuel oil systems, or fire mains, our product delivers consistent performance under pressure. The compact design saves space in pipework layouts, and the dual-action mechanism reduces the need for additional components, simplifying your system design and lowering total installed cost.
- Dual Functionality: Combines globe valve shut-off capability with automatic check valve backflow prevention, reducing component count and installation space.
- Material Excellence: High-grade marine bronze (ASTM B62/B584) offers outstanding resistance to saltwater corrosion, dezincification, and biofouling.
- Pressure & Temperature Range: Rated for PN1.0 to PN2.5 (150–300 psi working pressure) and suitable for temperatures from -10°C to +150°C, covering most marine medium requirements.
- Connection Versatility: Available with female threaded ends (NPT/BSP) or flanged ends (DIN PN10/16, ANSI 150) to match existing piping standards.
- Low Flow Resistance: Streamlined globe disc design minimizes pressure drop, ensuring efficient flow when open.
- Positive Sealing: Metal-to-metal or optional PTFE seat insert provides bubble-tight shut-off and reliable check action even at low backpressure.
- Easy Maintenance: Top-entry bonnet design allows quick inspection and replacement of internal parts without removing the valve from the pipeline.
- Certified Quality: BV (Bureau Veritas) type approval and ISO9001:2015 quality management system guarantee consistency and traceability.

The globe check valve design provides unique advantages over conventional swing or lift check valves. The flow path is forced to change direction, creating a pressure drop that keeps the disc seated until forward flow is established. This ensures positive closure and prevents water hammer in systems with fluctuating flow. The valve can also be manually operated like a globe valve for isolation, giving operators full control during maintenance or emergency shutdown.
All our marine bronze globe check valves undergo rigorous testing including hydrostatic shell tests (1.5x rated pressure), seat leakage tests (1.1x rated pressure), and material certification. Each valve is stamped with traceable identification and delivered with a test certificate. We offer both standard stock sizes and custom configurations (e.g., extended bonnet, special trim) to suit your specific requirements.
Trust the Experts: Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, has grown to export US$1–1.5 million annually to over 15 countries across North America, South America, Europe, Asia, Africa, and Oceania. Our BV-certified production facility in Shanghai ensures strict quality control from raw material to finished valve. With a dedicated team and quick lead times (15–30 days for standard orders), we are your reliable partner for marine valves.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a globe check valve and a standard check valve?
A: A globe check valve combines the functions of a globe valve (manual shut-off) and a check valve (automatic backflow prevention). It allows you to close the valve manually for isolation, while also acting as a non-return valve during normal operation. This saves space and reduces the number of fittings required. -
Q: Can this valve be used for potable water systems?
A: Yes, bronze is an approved material for potable water applications. However, please confirm with your local regulations. We can supply valves with NSF or WRAS certification upon request. -
Q: What pressure ratings are available?
A: Our standard range covers PN1.0, PN1.6, and PN2.5 MPa. For higher pressures (e.g., PN4.0), custom designs are available – please contact our sales team. -
Q: Do you provide flanged ends in ANSI standards?
A: Yes, we offer both DIN (PN10/16) and ANSI Class 150 flanges. Threaded ends can be supplied in NPT or BSP threads. Please specify your requirement when ordering. -
Q: How do you ensure the valve meets BV certification requirements?
A: Our valve design and production process follow BV Rules for classification societies. We conduct material traceability, hydrostatic testing, and leakage tests witnessed by BV surveyors if required. Each valve comes with a BV type approval certificate upon request. -
Q: What is the typical lead time for DN15-DN50 valves?
A: For standard sizes and materials, lead time is 15–20 working days. For custom orders or special trims, please allow 25–30 days. We also maintain a small stock for urgent needs. -
Q: Can the valve be installed vertically or horizontally?
A: The globe check valve can be installed in any orientation, but for optimal performance (especially the check function), we recommend horizontal installation with the bonnet facing upward. For vertical lines, ensure flow is upward to assist disc lifting. -
Q: What maintenance is required?
A: Periodic inspection of the disc, seat, and stem is recommended every 6 months in continuous service. If the valve is not used regularly, cycle it manually once a month to prevent sticking. Replacement parts (seat rings, disc, gaskets) are available from our stock.
