As a professional manufacturer with over 8 years of expertise in industrial valve production, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to offer our Factory Direct CB/T590 Marine Steam Globe Valve. Designed specifically for demanding marine steam applications, this valve combines robust construction, reliable performance, and direct-from-factory pricing. We ensure every valve is backed by a comprehensive Mill Test Report and a solid 12-month warranty, providing our global clients with confidence in quality and value.
Our CB/T590 Marine Steam Globe Valve is engineered for precise flow control and secure shut-off in shipboard steam systems, including boiler outlets, steam lines, and auxiliary equipment. Key features and advantages include:
- Precise Flow Regulation: The globe valve design, with its parabolic or needle-shaped disc, allows for fine control of steam flow, which is crucial for maintaining optimal system pressure and temperature.
- Robust Construction for Marine Environment: Manufactured from materials like cast steel or stainless steel, the valve body resists corrosion from salty, humid air, ensuring long service life even in harsh offshore conditions.
- Reliable Sealing Performance: The valve utilizes metal-to-metal or resilient seated sealing (depending on specification) to achieve bubble-tight shut-off, preventing steam leakage and enhancing system efficiency and safety.
- Compliance with Marine Standards: Adherence to the CB/T590 Chinese marine standard ensures the valve meets specific requirements for design, pressure, and materials suitable for marine applications.
- Factory Direct Value: By eliminating intermediaries, we offer competitive pricing without compromising on quality. Each valve undergoes stringent quality checks before shipment.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of a globe valve for steam service compared to other valve types?
A: Globe valves are particularly effective for steam applications because they offer excellent throttling capability and provide a reliable, leak-tight seal when fully closed. Their design allows for fine control of flow rate, which is essential for managing steam pressure and temperature in systems like boiler feed lines or distribution headers.
Q2: Does the CB/T590 standard make this valve suitable for international shipbuilding projects?
A: The CB/T590 is a recognized Chinese marine standard. While it is widely accepted, especially in projects involving Chinese shipyards or equipment, it is crucial to verify the specific classification society rules (like ABS, DNV, LR, etc.) or national standards required for your project. We can often customize valves to meet other international standards upon request.
Q3: What does the Mill Test Report include, and why is it important?
A: The Mill Test Report (MTR), also known as a Material Test Report or Certificate, is a document from the raw material mill. It certifies the chemical composition and mechanical properties (like tensile strength, yield strength) of the metal used for critical valve components (body, bonnet, disc, stem). It is a vital quality assurance document for traceability and compliance verification in marine and industrial projects.
Q4: Can this valve be supplied with different end connections?
A: Yes, we offer various end connections to suit different piping systems. Standard options include flanged ends (RF or RTJ face), threaded ends (NPT or BSP), and butt weld ends. Please specify your required connection type and relevant standards when inquiring.
Q5: What materials are typically recommended for the valve body in marine steam service?
A: For marine steam applications, cast carbon steel (WCB) is common for its strength and cost-effectiveness. For higher corrosion resistance, stainless steel grades like CF8 (AISI 304) or CF8M (AISI 316) are recommended. The choice depends on the steam pressure, temperature, and specific environmental conditions.
Q6: Is the 12-month warranty valid worldwide?
A: Yes, our 12-month warranty against manufacturing defects applies to all our customers globally. The warranty period typically starts from the date of shipment from our factory. Detailed warranty terms and conditions are provided with our commercial documents.
Q7: Do you offer actuated versions of this globe valve?
A: Absolutely. While the standard configuration is a manual handwheel, we can equip the valve with electric, pneumatic, or hydraulic actuators for remote or automated control. Please provide your required actuation specifications (torque, voltage, signal type) for a tailored solution.
Q8: What is your typical lead time for an order?
A: Lead time depends on the order quantity, specification complexity, and current production schedule. For standard configurations, lead times can range from 4 to 8 weeks. We provide a confirmed delivery schedule upon order confirmation and work diligently to meet project timelines.
