As a professional manufacturer with a strong presence in the global marine industry, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly introduces our CB/T590 Marine Globe Valve with Mounting Plate. Engineered for demanding marine and offshore applications, this valve series combines robust construction, reliable sealing, and convenient installation to ensure safe and efficient flow control in critical pipeline systems. With an annual export value demonstrating our international reach and trust, we deliver valves that meet the rigorous standards required by shipyards and marine operators worldwide.
Our CB/T590 Marine Globe Valve is designed to provide precise regulation and reliable shut-off in shipboard piping networks. The integrated mounting plate offers significant advantages for installation and maintenance in the confined spaces typical of marine environments.
Key Product Features & Technical Advantages:
- Robust Flanged Design with Mounting Plate: The valve features a flanged connection combined with a sturdy mounting plate. This design provides exceptional stability, reduces pipeline stress on the valve body, and simplifies alignment and bolting during installation, which is crucial for shipboard applications.
- Precise Flow Regulation & Tight Shut-off: Utilizing a globe valve design with a rising stem and disc, it allows for fine flow control and provides a bubble-tight seal when fully closed, ensuring zero leakage for safety and environmental protection.
- Durable Construction for Harsh Environments: Manufactured from high-grade materials such as cast steel, ductile iron, or optional stainless steel, the valve body resists corrosion from seawater and other aggressive media. Critical internal components like the stem and seat are made from stainless steel or bronze for long service life.
- Wide Size and Pressure Range: Available in a comprehensive range from DN50 to DN200 and rated for PN10 MPa pressure, this series covers the majority of requirements for main and auxiliary marine piping systems, including ballast, cooling, bilge, and general service lines.
- Standard-Compliant Design: The valve is designed in accordance with the Chinese CB/T590 standard for marine valves, ensuring compatibility and performance expectations are met for marine applications.
- Ergonomic Handwheel Operation: The handwheel is designed for easy manual operation, even with gloves, providing reliable control without the need for external power sources.

Frequently Asked Questions (FAQ)
Q1: What is the primary advantage of the mounting plate on this globe valve?
A: The mounting plate provides a stable, fixed point for installation. It simplifies alignment with the pipeline flanges, reduces stress transmitted from pipe movement to the valve body, and facilitates faster installation and future maintenance in space-constrained marine engine rooms and piping spaces.
Q2: Is this valve suitable for seawater service?
A: Yes, it is designed for marine applications. When specified with appropriate body materials like cast steel with suitable coatings or stainless steel, and corrosion-resistant trim (stainless steel stem/seat), it is well-suited for handling seawater, ballast water, and other corrosive marine media.
Q3: What pressure class does PN10 MPa correspond to in other standards (like ANSI)?
A: PN10 MPa is approximately equivalent to ANSI Class 600. It indicates the valve is rated for a nominal pressure of 10 Megapascals, which is suitable for many high-pressure marine systems.
Q4: Can you provide valves with different end connections besides flanged?
A: The standard design for the CB/T590 series with mounting plate is flanged. For other connection types (e.g., threaded, welded), please inquire as custom solutions may be available based on your specific requirements.
Q5: What is the typical lead time for an order of DN100 valves?
A: Lead times depend on order quantity and specific material requirements. For standard materials like cast steel, we generally maintain stock or short production cycles. Please contact our sales team with your quantity and specifications for an accurate delivery schedule.
Q6: Do you offer any certifications or test reports with the valves?
A: As an ISO9001-certified manufacturer, we perform routine quality tests. Standard documentation includes a material certificate and a factory test report (e.g., shell test, seat test). Specific marine society approvals (like ABS, DNV, etc.) can be discussed and arranged upon request.
Q7: What is the operating temperature range for the standard valve?
A: The standard temperature range is typically from -20°C to 200°C. This can vary based on the specific seat material chosen. For applications outside this range, please consult our technical team for material suitability.
Q8: How do I select the correct valve size (DN) for my application?
A: The DN size should match the nominal diameter of your connecting pipeline. Please provide your pipeline size, operating pressure, fluid type, and flow rate requirements. Our engineering team can assist in confirming the most suitable valve size and configuration for your system.
