As a professional valve manufacturer since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T590 Cast Steel Angle Globe Valve, engineered specifically for critical isolation duties in marine steam systems. With a proven track record of supplying high-performance valves to global markets across North America, Europe, Asia, and beyond, we understand the stringent demands of marine applications. This valve combines robust cast steel construction with a reliable angle pattern design to ensure safe, leak-tight shut-off, protecting your vessel's steam lines and associated equipment. Our commitment to ISO9001 certified manufacturing processes guarantees consistent quality and reliability in every unit we produce.
The CB/T590 Cast Steel Angle Globe Valve is a cornerstone of marine piping safety. Its defining angle pattern body provides a distinct advantage over straight-pattern valves by allowing a 90-degree change in flow direction, which reduces the number of pipe fittings required and minimizes pressure drop across the valve. This design is particularly beneficial in the confined spaces of engine rooms and other marine compartments. The valve is constructed from high-grade cast steel, offering exceptional strength and durability to withstand the high pressures and temperatures inherent in steam service. The metal-to-metal seating ensures a bubble-tight seal when closed, crucial for effective isolation during maintenance or in emergency situations.
Key Features & Technical Advantages:
- Superior Flow Control: The globe valve design provides excellent throttling capability and precise flow regulation, offering more control than simple on/off valves.
- Robust Construction: Manufactured from quality cast steel, the valve body and internals resist corrosion, erosion, and thermal stress common in steam environments.
- Enhanced Safety: Designed specifically for isolation, it provides a positive shut-off, enhancing the overall safety of the steam system.
- Space-Saving Design: The angle pattern eliminates the need for an elbow fitting, saving valuable space and reducing installation weight and cost.
- Long Service Life: Precision machining and durable materials contribute to a long operational lifespan with minimal maintenance requirements.

Frequently Asked Questions (FAQ)
Q1: What is the primary advantage of an angle pattern globe valve over a straight pattern?
A: The primary advantage is its ability to change the flow direction by 90 degrees within the valve body. This eliminates the need for a separate pipe elbow, resulting in a more compact installation, reduced pressure drop, and fewer potential leak points in the piping system.
Q2: Is this valve suitable for other fluids besides steam?
A: While specifically designed for marine steam line isolation, its cast steel construction and robust design make it suitable for other hot water, oil, gas, and general service applications where high temperatures and pressures are present. Always confirm material compatibility for your specific fluid.
Q3: What pressure classes are typically available?
A: Common pressure classes include ANSI Class 150, 300, and 600. The specific class available depends on the size and model. Please provide your required pressure rating for an accurate recommendation.
Q4: Does the valve come with any special trim options for erosive steam?
A: Yes, options such as Stellite or other hardened alloy trim on the seat and disc are available upon request to significantly enhance resistance to erosion and wear in high-velocity steam service.
Q5: What types of end connections do you offer?
A: Flanged ends are standard, complying with common standards like ANSI, JIS, or DIN. The face type (Raised Face, Flat Face) and drilling can be customized based on your piping specifications.
Q6: Can this valve be supplied with a gear operator?
A: Absolutely. For larger sizes or higher pressure classes where handwheel operation requires excessive force, a manual gear operator or other actuation methods (electric, pneumatic) can be provided.
Q7: What is the significance of the CB/T590 standard?
A: CB/T590 is a Chinese national professional standard for shipbuilding, specifically covering forged steel and cast steel globe valves. Valves manufactured to this standard are widely accepted in shipbuilding and offshore industries, ensuring certain levels of design, material, and testing requirements are met.
Q8: What is your lead time and packaging for export?
A: Lead times vary based on order quantity and specifications. Standard valves are typically available with shorter lead times. For export, valves are securely packaged in wooden cases to prevent damage during ocean freight, shipped from our main ports in Shanghai, Guangzhou, Hong Kong, or Beijing.
