With an annual export value of US$1–US$1.5 million and ISO9001 certification, we combine years of manufacturing expertise with strict quality control to deliver valves that meet the rigorous requirements of the maritime industry. This valve is available in sizes from DN50 to DN200mm, with pressure ratings of PN1.0 to PN1.6Mpa, and flanged connections for easy installation. Certified by Lloyd’s Register (LR) and American Bureau of Shipping (ABS), it provides reliable backflow prevention and flow regulation for seawater cooling, ballast, fire-fighting, and other shipboard piping systems.
Key Features & Advantages
- Durable Cast Iron Construction – High-quality gray cast iron body resists corrosion and wear in marine environments. Optional epoxy coating available upon request for enhanced protection.
- Combined Globe & Check Function – Serves as both a globe valve for throttling flow and a check valve to prevent reverse flow, saving space and reducing piping complexity.
- Flanged End Connections – Conforms to major flange standards (e.g., GB, DIN, JIS) for easy integration with existing marine piping.
- LR & ABS Type Approval – Fully certified by Lloyd’s Register and American Bureau of Shipping, ensuring compliance with international marine classification rules.
- Manual Handwheel Operation – Simple and reliable handwheel design allows precise flow adjustment and positive shut-off.
- Wide Size & Pressure Range – Covers DN50 to DN200 with PN1.0–1.6Mpa, suitable for medium- and low-pressure marine applications.
- Low Maintenance – Few moving parts and robust sealing design reduce the need for frequent servicing.

Frequently Asked Questions (FAQ)
-
Q: What media can this valve handle?
A: It is designed for clean water, seawater, cooling water, and fuel oil commonly used in marine systems. For aggressive media, please consult us for material upgrade options. -
Q: Is the valve suitable for vertical or horizontal installation?
A: The globe check valve can be installed in either horizontal or vertical piping with upward flow direction. For horizontal lines, the handwheel should be positioned on top. -
Q: Are LR and ABS certificates provided with each shipment?
A: Yes, we can provide LR and ABS type approval certificates for the valve series. A certificate of conformity for each batch is available upon request. -
Q: Can I get a valve with stainless steel disc instead of brass?
A: Absolutely. We offer optional disc materials including SS304, SS316, and aluminum bronze. Customization is subject to minimum quantity. -
Q: What is the typical lead time?
A: For standard sizes (DN50–DN150), lead time is 15–25 days after order confirmation. Larger sizes or custom orders may require 30–40 days. -
Q: Does the valve come with a gearbox for large sizes?
A: For DN200 and above, we recommend a gearbox for easier operation. It is available as an optional accessory. Standard manual handwheel is standard for DN50–DN150. -
Q: What is the standard packing for export?
A: Each valve is individually wrapped in foam and packed in a plywood crate for sea freight. Custom packaging like wooden pallets or cartons is available. -
Q: Do you offer after-sales support?
A: Yes, we provide technical support and spare parts for 12 months from shipment. Our engineering team can assist with installation or troubleshooting via email or video call.
