Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, is a professional manufacturer specializing in high-quality valve solutions for marine and industrial applications. Our API 609 Electric Butterfly Valve for Marine Ballast Water System 380V DN200 Class150 LR Type Approved is engineered to meet the rigorous demands of ballast water management systems, ensuring reliable performance and compliance with international standards. With an annual export value of US$1 million to US$1.5 million, we serve markets across North America, South America, Europe, Asia, and Africa, delivering valves that combine durability, precision, and safety.
This butterfly valve is designed specifically for marine ballast water systems, where corrosion resistance, leak-tight sealing, and precise flow control are critical. The LR Type Approval confirms its suitability for marine environments, while the electric actuator provides remote operation capability, reducing manual intervention and enhancing system automation. Whether for new builds or retrofits, this valve offers a cost-effective and reliable solution for shipowners and system integrators.
Below, we detail the key features, technical specifications, and benefits of this product to help you make an informed decision.
Key Features and Benefits
- API 609 Compliance: Manufactured in accordance with API 609 standards, ensuring dimensional consistency, pressure ratings, and material quality for reliable operation in demanding marine environments.
- LR Type Approved: Lloyd's Register (LR) type approval guarantees that the valve meets stringent marine classification requirements, making it suitable for ballast water systems on vessels subject to international regulations.
- Electric Actuator (380V): Equipped with a robust electric actuator operating at 380V, enabling remote control, automation integration, and precise positioning without manual effort. The actuator includes manual override for emergency use.
- DN200 Size and Class150 Rating: Designed for nominal diameter DN200 (8 inches) and Class150 pressure rating, suitable for standard marine piping systems with moderate pressure and flow requirements.
- Corrosion-Resistant Materials: Body and disc materials (e.g., ductile iron with epoxy coating, stainless steel disc) provide excellent resistance to seawater corrosion, extending service life and reducing maintenance costs.
- Bubble-Tight Sealing: The resilient seat design (e.g., EPDM or PTFE lined) ensures zero leakage at rated pressure, critical for ballast water treatment systems where contamination prevention is mandatory.
- Compact and Lightweight: Compared to gate or globe valves, the butterfly valve design reduces weight and space requirements, simplifying installation in confined engine rooms or pipe racks.
- Low Torque Operation: Optimized disc profile minimizes operating torque, allowing the electric actuator to operate efficiently and reducing power consumption.

Frequently Asked Questions (FAQ)
-
Q: What is LR type approval, and why is it important for marine valves?
A: LR type approval means the valve has been tested and certified by Lloyd's Register to meet specific marine industry standards for safety, reliability, and performance. It is important because many classification societies require such approvals for components used in ballast water systems, ensuring compliance with international regulations and simplifying vessel certification. -
Q: Can this valve be used for other fluids besides ballast water?
A: Yes, the valve is suitable for a wide range of fluids, including fresh water, seawater, treated effluent, and compatible chemicals. However, for specific applications, we recommend consulting our technical team to verify material compatibility and seat selection. -
Q: What is the typical lead time for this product?
A: Lead time depends on order quantity and customization requirements. For standard configurations (DN200, Class150, 380V actuator), typical lead time is 15–25 working days. Custom orders may require additional time. Please contact us for a precise delivery schedule. -
Q: Does the electric actuator come with a manual override?
A: Yes, all our electric actuators are equipped with a manual override handwheel for emergency operation during power loss or maintenance. This feature ensures continued valve control in critical situations. -
Q: What maintenance is required for this valve?
A: Routine maintenance includes periodic inspection of the actuator, seat, and disc for wear or corrosion. The resilient seat can be replaced without removing the valve body. Lubrication of the actuator gears may be required as per the user manual. We provide a detailed maintenance guide with each shipment. -
Q: Can the valve be customized for different voltage or actuator types?
A: Yes, we offer customization options for actuator voltage (e.g., 220V, 440V, DC), actuator type (e.g., pneumatic, hydraulic), and materials (e.g., duplex stainless steel, super duplex). Please provide your requirements for a tailored solution. -
Q: Is this valve suitable for high-pressure marine systems?
A: The Class150 rating is designed for moderate pressure applications typical in ballast water systems (up to 20 bar at ambient temperature). For higher pressure requirements, we recommend our Class300 or higher-rated valves, which are also available with LR approval. -
Q: How do I ensure proper installation of the valve?
A: Installation should follow the provided instruction manual, including correct flange alignment, gasket placement, and actuator wiring. We recommend professional installation by qualified marine engineers. Our technical support team is available to assist with any installation queries.
