Shanghai Zhibang Valve Manufacture Co., Ltd. has been a trusted manufacturer of high-performance industrial valves since 2016. Our SS316L Anti-Corrosion Marine Lug Butterfly Valve is engineered to meet the demanding requirements of marine, chemical, and liquid handling systems. Designed in strict accordance with GB/T3037-94 standard, this valve offers exceptional corrosion resistance, reliable sealing, and long service life. Whether you need a valve for bilge, ballast, or chemical liquid systems, our product delivers consistent performance under harsh conditions.
Product Features & Advantages
- Superior Material: Body and disc made of SS316L (low carbon stainless steel) providing excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments like seawater.
- Lug Design: The lug-style connection allows for easy installation, maintenance, and isolation of downstream piping without removing the valve from the line. Suitable for end-of-line or dead-end service.
- Compliance with GB/T3037-94: Manufactured strictly according to Chinese national standard for butterfly valves, ensuring dimensional accuracy, interchangeability, and quality assurance.
- Versatile Application: Ideal for bilge systems, ballast water management, chemical processing, and other liquid transfer systems where corrosion and leakage are critical concerns.
- Sealing Options: Available with PTFE, EPDM, or NBR seat materials to match different media and temperature requirements. The flexible seat design ensures bubble-tight shut-off.
- Actuator Compatibility: Can be fitted with manual handwheel, worm gear, pneumatic actuator, or electric actuator according to customer requirements. Mounting flange complies with ISO5211.
- Low Torque Operation: Optimized disc profile and stem design reduce operating torque, extending actuator life and reducing energy consumption.
- Pressure & Temperature Range: Suitable for working pressures up to PN16 (16 bar) and temperatures from -20°C to +200°C, depending on seat material selection.

Why Choose Our SS316L Marine Lug Butterfly Valve?
- Long-Term Durability: The SS316L material offers superior resistance to corrosion, especially in marine environments where saltwater and chloride exposure are constant. This reduces maintenance frequency and replacement costs.
- Easy Installation and Maintenance: The lug design allows the valve to be installed between flanges and removed without disturbing the downstream piping. This feature is particularly beneficial in confined marine spaces.
- Reliable Shut-Off: The resilient seat design provides bubble-tight sealing even at low pressure, ensuring no leakage of hazardous or valuable liquids.
- Customizable Options: We offer various seat materials, actuator types, and pressure ratings to meet specific project requirements. All valves undergo 100% pressure testing before shipment.
- Global Standards Compliance: In addition to GB/T3037-94, our valves can be manufactured to meet ANSI, DIN, or JIS standards upon request, ensuring compatibility with international piping systems.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of SS316L over SS304 for marine valves?
A: SS316L contains molybdenum, which significantly improves resistance to chlorides (like seawater) and offers better pitting and crevice corrosion resistance. It is the preferred material for marine and chemical applications. -
Q: Can this valve be used for end-of-line (dead-end) service?
A: Yes, the lug design allows the valve to be installed at the end of a pipeline and still maintain upstream pressure. This is a key feature of lug-type butterfly valves. -
Q: What is the maximum pressure rating available?
A: Standard ratings are PN10 and PN16. Higher pressure ratings (e.g., PN25) are available upon request, depending on size and material. -
Q: Do you provide certificates of material and pressure test?
A: Yes, we can provide material certificates (EN 10204 3.1) and hydrostatic test reports as required. Please specify your documentation needs when ordering. -
Q: What seat material is recommended for chemical liquids?
A: For most chemical services, PTFE (Teflon) seat is recommended due to its excellent chemical resistance and wide temperature range. For abrasive media, EPDM or NBR may be used depending on compatibility. -
Q: Can the valve be supplied with a pneumatic or electric actuator?
A: Absolutely. Our valves can be equipped with manual, worm gear, pneumatic, or electric actuators. The actuator mounting conforms to ISO5211, making it easy to retrofit. -
Q: Are sample valves available for testing before bulk order?
A: Yes, we offer sample orders to evaluate quality and performance. Contact our sales team for sample availability and lead time. -
Q: What is the typical lead time for standard sizes?
A: For sizes DN50-DN300, lead time is approximately 15-25 working days depending on quantity. Larger sizes may require 30-40 working days. We can expedite for urgent orders.
