As a professional manufacturer with a strong focus on marine and industrial valves, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Marine Steam Globe Valve manufactured to CB/T590 standard. Engineered for demanding marine steam applications, this valve combines robust cast steel construction with Stellite hardfacing on critical sealing surfaces, delivering reliable shut-off and flow control under high-temperature and high-pressure conditions. Our commitment to ISO9001-certified manufacturing ensures consistent quality and performance, making this globe valve a trusted component for shipbuilders and marine engineers worldwide.
This valve is specifically designed to handle saturated and superheated steam in marine piping systems. Its globe-style body design provides precise flow regulation and positive shut-off, which is essential for safety and operational efficiency onboard vessels. The primary construction material is high-grade cast steel, selected for its excellent strength and durability in corrosive marine environments.
Key Features and Technical Advantages:
- Superior Wear & Erosion Resistance: The seat and disc are hardfaced with Stellite alloy, a cobalt-chromium alloy known for its exceptional resistance to galling, erosion, and high-temperature wear. This significantly extends the valve's service life in abrasive steam service.
- Robust Construction: The valve body, bonnet, and other pressure-retaining parts are made from quality cast steel (typically ASTM A216 WCB or equivalent), providing the necessary mechanical strength for Class 150 pressure rating.
- Reliable Sealing Performance: The metal-to-metal seal created by the Stellite-faced seat and disc ensures tight shut-off, even after numerous cycles and exposure to thermal cycling, minimizing steam leakage and energy loss.
- Compliant Design: Manufactured in accordance with the Chinese CB/T590 standard for marine valves, ensuring dimensional compatibility and performance criteria are met for shipboard installations.
- Versatile Operation: The valve can be operated by handwheel, gearbox, or fitted with pneumatic or electric actuators (available upon request) for remote or automated control systems.
- Designed for Maintenance: Many designs feature a bolted bonnet or a pressure seal bonnet for easier access to internal components, facilitating inspection, maintenance, or seat replacement when necessary.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of Stellite hardfacing on the seat and disc?
A: Stellite hardfacing provides exceptional resistance to wear, galling (seizing), and erosion caused by high-velocity steam and particulate matter. This dramatically increases the valve's cycle life and maintains sealing integrity under harsh conditions. -
Q: Is this valve suitable for other services besides steam?
A: While optimized for steam, its robust cast steel construction and Stellite seats make it suitable for other high-temperature fluids, hot water, and non-corrosive gases. Please consult our engineering team for specific media compatibility. -
Q: Can you provide valves with different pressure classes, like Class 300?
A: Yes, we offer customization. While Class 150 is standard per the title, we can manufacture similar globe valves to higher pressure classes (Class 300, 600) upon request, with corresponding design changes. -
Q: What end connections are available?
A: Flanged connections are standard, complying with common standards like ANSI, JIS, or DIN. The specific face type (RF, RTJ) and drilling standard can be customized to match your existing pipeline flanges. -
Q: Do you offer actuated versions of this valve?
A: Absolutely. We can equip this globe valve with pneumatic (on/off or modulating) or electric actuators for integration into automated control systems. Actuator brand and specifications can be selected based on your requirements. -
Q: What is the typical delivery lead time?
A: For standard configurations, lead times are competitive. Exact timing depends on order quantity and specific customization. Our established manufacturing process and multiple export ports enable efficient logistics. -
Q: How does the CB/T590 standard compare to international standards like ANSI/ASME?
A: CB/T590 is a Chinese national standard specifically for marine valves, covering dimensions, materials, testing, and marking. It is widely recognized and accepted in shipbuilding. Valves can often be manufactured to meet both CB/T and relevant ANSI/ASME dimensional requirements. -
Q: What kind of testing is performed on these valves before shipment?
A> Each valve undergoes rigorous testing, which typically includes shell strength tests (hydrostatic), seat leakage tests (often using air or water), and operational tests to ensure smooth opening and closing. Detailed test reports are available.
