As a professional manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Marine Gate Valve. Engineered specifically for demanding seawater applications, this DN200 valve is constructed from premium corrosion-resistant bronze and rigorously designed to comply with the CB/T467 marine standard. Our years of expertise since 2016, backed by ISO9001 certified processes, ensure that every valve delivers exceptional performance, durability, and safety for critical marine piping systems worldwide, from ballast and cooling lines to general seawater service.
This valve is built to withstand the harsh, corrosive marine environment, offering a robust solution for shipbuilders, ship repair yards, offshore platform operators, and marine equipment suppliers. We understand the critical need for zero leakage and long service life in maritime applications, which is why our marine gate valve incorporates advanced design features and superior materials. Choosing our product means investing in operational reliability, reduced maintenance costs, and enhanced safety for vessels and offshore installations.
Key Features & Technical Advantages:
- Superior Corrosion Resistance: The valve body, bonnet, and trim are manufactured from specially selected bronze alloys, offering outstanding resistance to seawater, salt spray, and other corrosive elements commonly found in marine environments, significantly extending service life.
- Strict CB/T467 Compliance: The design, materials, manufacturing, and testing strictly adhere to the Chinese CB/T467 standard for marine valves, ensuring the product meets the specific performance, safety, and quality requirements for shipboard use.
- Robust DN200 Design: With a nominal diameter of DN200, this valve is ideal for larger seawater pipelines, providing reliable flow control with minimal pressure drop when fully open due to its straight-through gate design.
- Reliable Sealing Performance: Features a precision-machined wedge gate and seat arrangement. Options include metal-to-metal or resilient seated designs to achieve bubble-tight shut-off, preventing seawater ingress and ensuring system integrity.
- Durable Operation Mechanism: Equipped with a sturdy handwheel for manual operation. For higher torque requirements or remote operation needs, a gearbox operator is available as an optional accessory, facilitating easier operation under high differential pressures.
- Versatile Flanged Connections: Comes with standard flanged ends (e.g., PN16, ANSI 150#), designed for easy and secure bolting to pipeline flanges, ensuring a leak-free connection. Other connection standards can be customized upon request.
- Low Maintenance Design: The simple and robust gate valve design requires minimal maintenance. The stem is properly sealed with packing to prevent leakage, and the design allows for potential in-line maintenance or repair in many cases.
