Marine Lug Butterfly Valve With 12-month Warranty, DN400 and DN600 Sizes
Product Spotlights
As a professional manufacturer specializing in industrial valves since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our robust Marine Lug Butterfly Valve series, designed for DN400 and DN600 pipelines. Engineered with precision and backed by our ISO9001 certified production system, these valves offer reliable flow control in demanding marine and industrial environments. Our commitment to quality is reflected in the 12-month warranty, providing assurance for your critical applications.
Key Features and Technical Advantages:
- Durable Lug Design: The lug-style body provides a secure, bolted connection to the pipeline flanges, ideal for systems where the valve may need to be isolated or removed. This design offers excellent structural integrity.
- Precision Size Options: Available in DN400 (400mm nominal diameter) and DN600 (600mm) sizes, catering to large-diameter piping requirements common in shipboard systems, water treatment plants, and bulk fluid handling.
- Versatile Material Selection: The valve body and disc can be manufactured from high-grade cast steel for general service or corrosion-resistant stainless steel for seawater and aggressive media. Material choice is customizable based on your specific application needs.
- High-Performance Sealing: The sealing ring is typically made from EPDM (for water and general fluids) or PTFE (for higher temperatures and chemicals). This ensures a tight shut-off and long service life.
- Flexible Operation: The valve can be operated via a manual handwheel or equipped with a gearbox for easier operation in high-pressure or large-size applications. Actuation options are available upon request.
- Streamlined Flow Control: The butterfly disc design offers low flow resistance when open, enabling efficient throughput, and provides a quick, quarter-turn operation for opening and closing.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a lug-style butterfly valve over a wafer-style?
A: A lug-style valve has threaded lugs (or ears) around its body. This allows it to be bolted directly to each pipeline flange independently. This design is beneficial for end-of-line applications or when the valve needs to be removed without dismantling the entire pipe section, offering more installation flexibility.
-
Q: Are these DN400 and DN600 valves suitable for seawater applications?
A: Yes, they are designed for marine use. For seawater or other corrosive media, we recommend selecting a stainless steel body (such as 316 stainless steel) and a compatible sealing material like PTFE to ensure corrosion resistance and long-term performance.
-
Q: What does the 12-month warranty cover?
A: Our warranty covers defects in materials and workmanship under normal use conditions for a period of 12 months from the date of shipment. It assures the fundamental quality and reliability of the valve.
-
Q: Can these valves be operated automatically (with an actuator)?
A: While the standard offering is manual or gear operation, these lug butterfly valves can be adapted for automated control. The shaft design is compatible with various electric, pneumatic, or hydraulic actuators. Actuator options are available upon request.
-
Q: What pressure ratings are available for the DN400 and DN600 sizes?
A: Pressure ratings depend on the selected body material, disc thickness, and design. Standard ratings are available, and higher pressure classes can be engineered. Please provide your required pressure class (e.g., PN10, PN16) so we can confirm the suitable configuration.
-
Q: How does your ISO9001 certification benefit the product?
A: Our ISO9001 certification signifies a systematic, documented quality management process throughout manufacturing. It ensures consistent production standards, thorough inspection procedures, and traceability, leading to reliable and repeatable product quality.
-
Q: What are the typical delivery lead times for these valves?
A: Lead times vary based on order quantity, material specifications, and customization. For standard material configurations in DN400 and DN600, we typically aim for efficient production schedules. Specific lead times can be provided upon inquiry.
-
Q: Do you provide technical drawings or installation guidelines?
A: Yes, as a manufacturer, we provide detailed technical drawings (dimensional outlines, flange details) and installation/maintenance guidelines for all our valves to assist with proper integration into your system.
