Shanghai Zhibang Valve Manufacture Co., Ltd
As a dedicated manufacturer of industrial valves since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd proudly presents our Marine Grade Butterfly Valve DN800 with Flanged Connection. This valve is engineered specifically for demanding marine and offshore applications, offering a robust solution for flow control in large-diameter piping systems. With an annual export value exceeding one million USD and a presence in global markets including North America, Southeast Asia, and Europe, our products are trusted for their reliability and performance. This DN800 butterfly valve represents our commitment to providing high-quality, standard-compliant components that meet the rigorous requirements of shipbuilding, port infrastructure, and industrial marine projects.
Key Features and Technical Specifications:
- Marine-Grade Construction: Designed for harsh saltwater environments, the valve body and disc are typically constructed from corrosion-resistant materials like cast steel or stainless steel to ensure long-term durability and prevent failure due to seawater exposure.
- DN800 Large Diameter: With a nominal diameter of 800mm, this valve is ideal for main pipeline systems, ballast water control, cooling water circuits, and other critical large-flow applications on vessels and offshore platforms.
- Flanged Connection: The standard flanged ends provide a secure, leak-resistant connection to the piping network, facilitating easier installation, maintenance, and replacement compared to other connection types.
- Standard Compliant Design: Manufactured adhering to relevant industry and marine standards, ensuring compatibility, safety, and performance expectations are met for international projects.
- Excellent Sealing Performance: Utilizes a high-quality seat (often rubber or PTFE) that provides a tight seal when closed, minimizing leakage and ensuring efficient system isolation.
- Versatile Operation Options: Available with manual handwheel operation, gearbox operation for easier torque management, or can be configured for actuator operation (electric, pneumatic, or hydraulic) for remote or automated control integration.
- Broad Application Scope: Beyond core marine uses, this valve is suitable for related industries such as offshore oil & gas, coastal power plants, desalination plants, and large-scale industrial water management systems.

Frequently Asked Questions (FAQ):
-
Q: What exactly does "Marine Grade" mean for this butterfly valve?
A: "Marine Grade" indicates that the valve is specifically designed and constructed with materials and features to withstand the corrosive environment of seawater and marine applications. This typically involves using corrosion-resistant alloys for the body and disc and ensuring the sealing components are suitable for prolonged exposure to saltwater. -
Q: Is the DN800 size a standard size, and what are its common applications?
A: DN800 (800mm nominal diameter) is a standard large size in piping. Common applications include main ballast water lines on large vessels, primary cooling water circuits for ships or offshore platforms, large intake/discharge lines for desalination plants, and bulk fluid transfer systems in port infrastructure. -
Q: Can this flanged valve be connected to pipes with different flange standards?
A: The valve is manufactured with standard flange dimensions. It is crucial to specify the required flange standard (e.g., ANSI, DIN, JIS) during inquiry to ensure compatibility. Custom flange dimensions might be available upon request. -
Q: What are the available operation methods for this valve?
A> The valve can be supplied with a manual handwheel for direct operation, a gearbox operator to reduce required operating torque, or it can be prepared for attachment of an actuator (electric, pneumatic, hydraulic) for automated control. The choice depends on your system's control requirements. -
Q: What pressure and temperature ranges can this DN800 butterfly valve handle?
A> Standard pressure ratings (like PN10 or PN16) are available. The operational temperature range depends significantly on the seat material chosen (e.g., rubber seats have a lower max temperature than PTFE seats). Specific ratings can be provided based on your material selection and application details. -
Q: Does Shanghai Zhibang provide customization for specific project requirements?
A> Yes, as a manufacturer, we can discuss customization options such as specific material grades, alternative seat materials, special coatings, or actuator preparation. Please contact us with your detailed requirements. -
Q: What certifications support the quality of this valve?
A> Our manufacturing facility is certified under ISO9001 for quality management systems. The valve itself is manufactured to comply with relevant industrial and marine standards applicable to its design and application. -
Q: How does the company handle shipping and logistics for international orders?
A> We ship from major Chinese ports including Shanghai, Guangzhou, Hongkong, and Beijing, offering flexibility. We work with clients to determine the most efficient shipping method based on order size, destination, and timeline.
