As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing reliable and durable marine valves. Our Marine Angle Globe Valve, designed specifically for bilge and ballast systems in strict accordance with the CB/T590-1995 standard, is engineered to meet the rigorous demands of maritime operations. With an annual export value reaching up to US$1.5 million and a strong presence in global markets from North America to Oceania, we understand the critical need for valves that ensure safety, efficiency, and longevity on board. This valve represents our commitment to quality, offering a robust solution for precise flow control in challenging marine environments.
This valve is constructed for superior performance and durability. The angle design allows for a 90-degree change in flow direction, saving space and reducing the number of pipe fittings required in complex bilge and ballast piping layouts. Its globe valve mechanism provides excellent throttling capability and shut-off, which is crucial for managing water levels and ensuring vessel stability.
Key Features & Technical Advantages:
- Rugged Construction: Manufactured from high-grade materials such as cast steel or bronze, selected for excellent corrosion resistance in seawater applications.
- Standard Compliance: Adheres to the CB/T590-1995 design standard, ensuring compatibility and reliability within marine system specifications.
- Enhanced Sealing: Features a precision-machined seat and disc arrangement, often with resilient or metal-to-metal sealing, for bubble-tight shut-off and minimal leakage.
- Easy Operation & Maintenance: Designed with a standardized handwheel or optional gear operator. The bolted bonnet design facilitates easier inspection and maintenance of internal parts.
- Versatile Configurations: Available in various pressure classes (e.g., Class 150, Class 300), connection types (flanged, threaded), and material options to suit specific project requirements.
The primary benefit for shipyards, vessel owners, and marine engineers is the assurance of a dependable component that contributes to the overall safety and operational efficiency of the vessel. By choosing this valve, you minimize the risk of system failure, reduce long-term maintenance costs, and ensure compliance with marine engineering standards.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of an angle globe valve over a straight pattern one for bilge systems?
A: The angle design integrates a 90-degree elbow into the valve body. This saves significant space and reduces installation costs by eliminating the need for a separate pipe elbow, which is particularly beneficial in the confined spaces of ship bilge and ballast piping. -
Q: Is this valve suitable for use with seawater?
A: Yes, it is designed for marine service. We offer material options like bronze and specified grades of cast steel that provide good resistance to corrosion from seawater. The exact material selection should be based on the specific fluid and operating conditions. -
Q: Can you provide valves with certifications like ABS, DNV, or LR?
A: Our standard production follows the CB/T590-1995 standard. Certification from specific classification societies (ABS, DNV, LR, etc.) can be arranged as a special order. Please inform us of your certification requirements during inquiry. -
Q: What is the typical delivery lead time for an order?
A: Lead time depends on order quantity, specification, and material availability. For standard specifications, we generally maintain a competitive lead time. We provide a confirmed schedule upon receipt of your official order. -
Q: Do you offer customization for different pressure ratings or end connections?
A: Absolutely. We can customize valves to meet various pressure classes (PN/Class) and provide different end connections such as flanged (RF, RTJ), threaded (NPT, BSP), or weld ends to match your piping specifications. -
Q: How does your company ensure product quality?
A: Our manufacturing is governed by an ISO9001 Quality Management System. Each valve undergoes rigorous inspections and tests, including pressure tests, to ensure it meets the required performance standards before shipment. -
Q: What are the main applications for this valve besides bilge and ballast systems?
A> While designed for bilge and ballast, its robust construction makes it suitable for other marine services requiring on/off and throttling control, such as general seawater lines, cooling water systems, and tank filling/discharge lines. -
Q: What is your main shipping port and which incoterms do you usually offer?
A: We primarily ship from Shanghai, Guangzhou, and Hong Kong ports. We are flexible with standard incoterms like FOB, CIF, or CFR, depending on the destination and customer preference.
