As a leading manufacturer specializing in industrial valves since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents its robust Marine Large Diameter Butterfly Valve DN1000. Engineered for demanding marine and offshore applications, this valve combines reliable performance with operational efficiency, making it a trusted component for shipbuilding, port facilities, and offshore platforms worldwide.
Our valves are designed to handle large-volume fluid control with precision and durability. The flanged connection ensures secure installation, while the gear operation provides smooth and controlled actuation even under high-pressure conditions. With an annual export value ranging between US$1 Million and US$1.5 Million, we have established a strong presence in markets across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, and beyond, demonstrating our commitment to global quality standards.
This product is manufactured under our ISO9001-certified quality management system, ensuring consistent excellence from raw material selection to final assembly. We ship from major ports including Shanghai, Guangzhou, Hongkong, and Beijing, facilitating timely delivery to clients around the world.
Key Features & Technical Specifications:
- Large Diameter Design: The DN1000 (1000mm) nominal diameter is ideal for main pipeline systems requiring high flow capacity, reducing the need for multiple smaller valves.
- Flanged Connection: Standard flanged ends (typically DIN, ANSI, or JIS standards) allow for straightforward integration into existing piping networks, providing a leak-resistant and stable connection.
- Gear Operated Mechanism: The manual gear operator offers precise angular control of the disc, enabling fine flow adjustment and reliable shut-off. It reduces operator effort compared to direct lever operation, especially for large diameters.
- Durable Construction: Available in materials like Carbon Steel, Stainless Steel, or Duplex Steel to suit different corrosive environments (seawater, chemicals, etc.). The disc and shaft are robustly designed to withstand marine conditions.
- Versatile Sealing Options: Sealing rings can be customized using materials such as Rubber, PTFE, or EPDM to match specific media temperature and chemical compatibility requirements.
- Broad Pressure & Temperature Range: Engineered for standard pressure ratings (e.g., PN10, PN16, PN25) and a typical operating temperature range from -20°C to +120°C, suitable for various marine service conditions.
- Low Maintenance: Simple design with minimal moving parts reduces maintenance frequency and costs, a critical advantage in remote offshore locations.

Frequently Asked Questions (FAQ)
Q1: What are the main applications for this DN1000 butterfly valve?
A: This valve is primarily designed for marine and offshore applications, such as ballast water systems, seawater cooling lines, fuel transfer pipelines, and general shipbuilding plumbing. Its large diameter suits main trunk lines where high flow rates are required.
Q2: Can the flanged connection be customized to match specific international standards?
A: Yes. While common standards like DIN, ANSI, or JIS are typically offered, flange dimensions and face types can be customized upon request to align with your project's specific piping standard requirements.
Q3: Why is a gear operator preferred over a simple lever for this large valve?
A: A gear operator provides a mechanical advantage, making it easier to turn the large disc against system pressure. It offers finer control over the opening angle and ensures a more secure seal, which is crucial for large-diameter, high-pressure applications.
Q4: What material options are available for corrosive seawater environments?
A: For highly corrosive conditions like seawater, we recommend Stainless Steel (e.g., 316) or Duplex Steel. The sealing material (e.g., EPDM or PTFE) can also be selected for compatibility with seawater temperature and chemistry.
Q5: Is this valve suitable for high-pressure systems?
A: This valve is designed with pressure ratings such as PN16 or PN25, making it suitable for many marine pressure systems. The exact pressure capability depends on the selected material and seal. For ultra-high pressure applications, please consult our engineers for a tailored solution.
Q6: How does the ISO9001 certification benefit the product quality?
A: Our ISO9001 certification means our entire manufacturing process—from design, material procurement, production, testing, to packaging—follows a documented quality management system. This ensures consistent product performance, reliability, and traceability.
Q7: What is the typical delivery time, and from which ports do you ship?
A: Delivery time depends on order quantity and customization. Standard configurations typically have shorter lead times. We ship from major ports including Shanghai, Guangzhou, Hongkong, and Beijing, offering flexible logistics options to global destinations.
Q8: Can this valve be equipped with an actuator for automated control?
A: While this model is described as gear-operated (manual), the design can often be adapted for actuator mounting (electric, pneumatic, or hydraulic). This is a customizable feature; please specify your automation requirements during inquiry.
