As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in delivering high-performance, reliable valves for demanding industrial applications. Our Flanged Angle Globe Valve, manufactured strictly per the CB/T590-1995 standard, is engineered specifically for the rigorous conditions of marine piping systems. This manual-operated valve offers superior flow control, durability, and safety, making it an essential component for shipbuilders, offshore platforms, and marine engineering contractors worldwide.
The angle globe design is a key feature, providing a 90-degree change in flow direction. This configuration offers significant advantages over straight-pattern globe valves in space-constrained shipboard environments.
- Optimized Flow Path: The angled body reduces flow turbulence and pressure drop compared to a standard globe valve, enhancing system efficiency.
- Robust Construction: Manufactured from high-grade materials like cast steel (WCB), stainless steel (CF8/CF8M), or ductile iron, ensuring corrosion resistance and long service life in saltwater atmospheres.
- Precise Throttling: The manual handwheel allows for fine, incremental control of fluid flow, which is critical for balancing and regulating marine systems.
- Excellent Shut-off Capability: Features a disc and seat design that provides tight, bubble-tight sealing when fully closed, preventing leaks in vital systems.
- Easy Maintenance: Many designs feature a bolted bonnet or gland, allowing for easy access to internal parts for inspection, repair, or replacement without removing the entire valve from the line.
- Versatile Mounting: The flanged ends conform to standard dimensions (e.g., ANSI, JIS, DIN), facilitating straightforward installation and integration into existing marine piping networks.
The valve's technical specifications are critical for engineering selection. Below is a summary of typical parameters:
| Parameter | Typical Specification |
| Design & Manufacturing Standard | CB/T590-1995 (Chinese Shipbuilding Standard) |
| Pressure Class | PN16, PN25, PN40; Class 150, Class 300 (customizable) |
| Temperature Range | -20°C to 425°C (dependent on trim material) |
| Connection | Flanged, RF or FF face |
| Operation | Manual Handwheel |
| Flow Direction | Flow under the seat (standard) |

Frequently Asked Questions (FAQ)
-
Q: What does "CB/T590-1995" mean for this valve?
A: It refers to the Chinese shipbuilding industry standard that specifies the design, dimensions, materials, testing, and marking requirements for flanged angle globe valves. Compliance ensures the valve is suitable for marine applications. -
Q: Can this valve be used with fluids other than water?
A: Yes. The specific material selection (body, trim, seat) determines compatibility. We offer valves suitable for seawater, oil, steam, and other media common in marine systems. Please specify your medium for correct material recommendation. -
Q: Is the manual operation suitable for frequently adjusted lines?
A: While excellent for throttling, manual valves are typically used for isolation or occasional regulation. For lines requiring frequent or remote adjustment, actuated versions (electric, pneumatic) are available upon request. -
Q: What flange standards do you support?
A> We commonly produce valves with ANSI B16.5, JIS B2220, or DIN flanges. The specific standard and pressure class can be customized to match your piping specifications. -
Q: What is the lead time for an order?
A: Lead time depends on order quantity, size, and material specifications. Standard configurations typically have shorter lead times. We provide accurate timelines upon receipt of your detailed inquiry. -
Q: Do you provide documentation and certification with the valves?
A> Yes. We can provide material test reports, inspection reports, and certificates of conformity. Dimensional drawings are also available for engineering review. -
Q: How does the angle design benefit installation?
A: The 90-degree angle allows the valve to be installed in a corner, saving space and often eliminating the need for an extra pipe elbow, which reduces weight, potential leak points, and installation labor. -
Q: Are spare parts like seals and gaskets available?
A: Absolutely. We maintain an inventory of critical spare parts and can supply them separately to support your maintenance needs, ensuring long-term operability of the valve.
