As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our DN300 Large Diameter Gate Valve, engineered specifically for demanding marine applications. With an annual export value demonstrating our global reach, we combine rigorous manufacturing under ISO9001 standards with deep industry expertise to deliver valves that ensure reliability, safety, and performance in critical shipboard systems. This valve is not just a component; it's a commitment to seamless fluid control and operational integrity for your maritime assets.
Our DN300 Gate Valve is designed to meet the stringent requirements of the maritime industry, offering robust construction and compliance with the CB/T3591 standard. Its large diameter makes it ideal for main pipeline applications on vessels, including ballast, bilge, cooling water, and fuel oil systems.
Key Features & Technical Advantages:
- Standard Compliance: Manufactured in strict accordance with the CB/T3591 standard for marine valves, ensuring compatibility and reliability for shipbuilding and offshore applications.
- Robust Construction: The valve body is typically crafted from high-grade cast steel or ductile iron, providing exceptional strength and corrosion resistance to withstand harsh marine environments, including saltwater exposure.
- Superior Sealing: Features a flexible wedge or parallel slide gate design paired with stainless steel or bronze seats, ensuring a bubble-tight shut-off and minimizing internal leakage over extended service life.
- Low Flow Resistance: The full-bore design offers a straight-through flow path when fully open, resulting in minimal pressure drop and efficient fluid transfer, which is crucial for large-diameter pipeline efficiency.
- Versatile Actuation: Available with standard handwheel operation for manual control, or optionally equipped with gear operators or electric actuators for remote and automated valve control systems.
- Durable Stem & Packing: Utilizes a rising stem design for clear visual indication of valve position. The stem is protected by high-quality packing (e.g., graphite) for reliable sealing and easy maintenance.

Frequently Asked Questions (FAQ):
-
Q: What does compliance with CB/T3591 standard mean for this valve?
A: Compliance with the CB/T3591 standard signifies that the valve is designed, manufactured, and tested according to specific Chinese shipbuilding standards for marine valves. It ensures dimensions, materials, pressure ratings, and testing procedures are suitable for marine applications, offering reliability and interchangeability in ship systems. -
Q: Can this DN300 valve be used with media other than water?
A: Yes. Depending on the selected body and seat materials (e.g., stainless steel), this valve can handle various media common in marine settings, including seawater, fuel oil, lubricating oil, and compressed air. Please specify your media during inquiry for correct material recommendation. -
Q: What are the available flange standards and pressure ratings?
A: We typically manufacture valves according to GB (Chinese) flange standards as per CB/T3591. However, we can also produce valves with JIS, DIN, or ANSI standard flanges upon request. Standard pressure ratings are PN10, PN16, and PN25, with other classes available as a customization. -
Q: Is the valve suitable for both above-deck and below-deck installations?
A> The valve's material construction (e.g., corrosion-resistant cast steel or coated ductile iron) makes it suitable for various shipboard locations. However, for particularly harsh environments, specifying stainless steel or additional protective coatings is advisable. -
Q: What types of actuation can be provided?
A: The valve is supplied with a standard handwheel. Options include bevel gear operators for high-torque manual operation or electric actuators for integration into automated control systems. The specific actuator model can be selected based on your required torque and control signals. -
Q: What is the typical delivery time for an order of these valves?
A> Delivery time depends on order quantity, material specifications, and optional features. For standard configurations, we can often provide a competitive lead time. We ship from multiple ports in China to facilitate efficient logistics to your destination. -
Q: Do you provide documentation and certifications with the valves?
A: Yes. Along with the product, we provide essential documentation such as a material certificate, product test report (including shell test and seat test), and a manual. A certificate of conformity stating compliance with CB/T3591 and ISO9001 can also be supplied. -
Q: Can you produce this valve in diameters larger than DN300?
A: Yes. As a manufacturer, we have the capability to produce large diameter gate valves in sizes beyond DN300. Please contact our sales team with your specific size and pressure requirements for a customized solution.
