Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016 and ISO9001 certified, specializes in producing high-performance industrial valves for demanding global markets. Our CBT4303 Marine Butterfly Check Valve is engineered for reliability in marine and offshore applications, featuring a robust carbon steel body designed to withstand pressures up to 10 Bar. This valve ensures fluid flow control with minimal maintenance, making it a trusted component for shipbuilding, pipeline systems, and coastal infrastructure.
The core value of the CBT4303 lies in its durable construction and efficient non-slam operation. Unlike conventional check valves, our butterfly design provides quick, silent closing to prevent backflow, protecting pumps and pipelines from damage. This is critical in marine environments where system integrity is paramount.
- Carbon Steel Body: Offers excellent corrosion resistance and mechanical strength, suitable for seawater and other corrosive media.
- Butterfly Disc Mechanism: Ensures fast response and low flow resistance, enhancing system efficiency.
- 10 Bar Pressure Rating: Certified for stable performance under high-pressure conditions common in marine engineering.
- Versatile Installation: Can be installed horizontally or vertically without performance degradation.
- Rubber Seal (Standard): Provides reliable sealing; alternative materials like EPDM or Viton are available upon request for specific media.
- Flanged Connections: Standard design for easy integration into existing piping; other connection types can be customized.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of a butterfly check valve compared to other types?
A: Butterfly check valves, like the CBT4303, typically offer lower flow resistance and a quieter, non-slam closing action. This reduces pressure drop in the system and minimizes wear and noise during operation, which is beneficial for continuous marine applications.
Q2: Is the carbon steel body suitable for seawater applications?
A: Yes, carbon steel provides good corrosion resistance and mechanical strength for seawater environments. For highly corrosive conditions, we can discuss optional coatings or alternative body materials upon request.
Q3: Can this valve handle pressures higher than 10 Bar?
A: The standard CBT4303 is rated for a maximum working pressure of 10 Bar. For higher pressure requirements, please contact us; we may have customizable options or can recommend other models from our range.
Q4: What are the available connection standards for the flanged ends?
A: Standard flanges conform to common industrial dimensions. Specific standards like ANSI or DIN can be provided as customizable features. Please specify your requirement during inquiry.
Q5: How does the valve perform in vertical installation?
A: The CBT4303 is designed for both horizontal and vertical installation. Its internal mechanism ensures reliable operation regardless of orientation, making it versatile for different pipeline layouts.
Q6: What is the typical lead time for delivery?
A: Lead time depends on order quantity and customization. Standard sizes are often available for prompt shipment from our Shanghai, Guangzhou, Hongkong, or Beijing ports. We provide estimated timelines upon order confirmation.
Q7: Are there different seal materials available?
A: The standard seal is rubber, suitable for many media. For aggressive chemicals or specific temperatures, materials like EPDM or Viton are optional. Discuss your media type with our technical team for the best recommendation.
Q8: Does the manufacturer provide any warranty or after-sales support?
A: As an ISO9001 certified manufacturer, we ensure product quality. Warranty terms and after-sales support are provided based on the specific order and application. Details can be clarified during the purchasing process.
