As a professional manufacturer of industrial valves with a strong presence in the marine sector, Shanghai Zhibang Valve Manufacture Co., Ltd. introduces its robust DN150 Marine Ball Valve, engineered specifically for the demanding environment of Ship Exhaust Gas Desulfurization (EGD) Towers, commonly known as scrubbers. This valve is a critical component designed to ensure reliable isolation and control within scrubber systems, which are essential for vessels to comply with stringent international emissions regulations like IMO 2020. Our expertise, backed by ISO9001-certified manufacturing processes since 2016, ensures that this valve delivers the durability, corrosion resistance, and operational reliability required for continuous marine service, protecting your investment and supporting environmental compliance.
The harsh conditions inside an exhaust gas scrubber—involving a mix of hot, corrosive exhaust gases, seawater, and abrasive slurry—demand a valve built to last. Our DN150 ball valve is constructed to meet this challenge head-on. Its design focuses on providing a tight shut-off, ease of operation, and minimal maintenance, even in the presence of particulate matter common in scrubber loops. By choosing a valve specifically tailored for this application, ship owners and system integrators can significantly enhance the overall reliability and uptime of their emissions abatement systems.
Core Product Features & Technical Advantages:
- Superior Corrosion & Erosion Resistance: Available in material grades such as carbon steel with special coatings or stainless steel (316/316L), the valve body and internals are selected to withstand the corrosive cocktail of sulfuric acid condensate and seawater. The seat materials, including reinforced PTFE or specialized metal seats, offer excellent resistance to both corrosion and abrasion from slurry particles.
- Robust, Low-Maintenance Design: The full-port or standard-port design minimizes pressure drop across the valve, which is crucial for system efficiency. The stem is designed with anti-blowout features and effective sealing to prevent leakage. A extended bonnet option is available for insulation applications or to protect packing from extreme temperatures.
- Flexible Actuation & Operation: The valve is supplied as standard with a manual lever for easy quarter-turn operation. To meet the needs of automated scrubber systems, it can be seamlessly fitted with pneumatic, hydraulic, or electric actuators. Gear operators are also available for valves requiring higher torque in manual applications.
- Marine-Grade Construction & Compliance: Manufactured following relevant ISO, ANSI/ASME, and marine classification society guidelines (upon request), the valve is built for marine duty. Flanges conform to standards like ANSI B16.5 Class 150, ensuring easy integration into existing scrubber piping.
- Enhanced Sealing Integrity: The ball and seat are precision machined and lapped to ensure bubble-tight sealing, critical for isolating sections of the scrubber for maintenance or controlling flow. Multiple sealing points, including body seals and stem packing, are designed for long-term integrity.

Benefits for Your Scrubber System:
- Increased System Reliability: Reduces the risk of unplanned downtime due to valve failure in critical scrubber circuits.
- Lower Lifetime Cost: Durable materials and design lead to longer service intervals and reduced replacement costs.
- Simplified Maintenance: Modular design and accessible components allow for easier inspection and part replacement if needed.
- Regulatory Compliance Support: A reliable valve ensures the scrubber system functions as designed, helping maintain compliance with emission limits.
- Design Flexibility: Multiple material and actuation options allow the valve to be customized for specific scrubber designs (open-loop, closed-loop, hybrid).
Frequently Asked Questions (FAQ):
-
Q: Why is a standard ball valve not suitable for scrubber service?
A: Scrubber service involves a highly corrosive and abrasive medium (acidic slurry). Standard valves may use materials or seals that degrade quickly in this environment, leading to frequent leaks and failures. Our valve uses specialized, corrosion-resistant alloys and robust seat materials specifically chosen for this duty. -
Q: Can this valve handle both the seawater inlet and the exhaust gas/scrubber slurry lines?
A: Yes, but material selection is key. For seawater inlet (clean service), standard stainless steel may suffice. For the more aggressive scrubber slurry and exhaust lines, we often recommend upgraded materials like higher-grade stainless steel (e.g., 316L) or carbon steel with appropriate internal coatings for optimal cost-performance balance. -
Q: Is the valve suitable for automated control within the scrubber's PLC system?
A> Absolutely. This DN150 ball valve is designed for easy integration with various actuators (pneumatic, electric, hydraulic). We can supply the complete assembly—valve, actuator, limit switches, and solenoid valves—ready for connection to your control system. -
Q: What is the typical delivery lead time for this product?
A> For standard configurations, lead time is generally 4-6 weeks. For customized orders involving special materials, actuators, or testing, the lead time may be extended. We provide accurate timelines upon order confirmation. -
Q: Do you provide documentation like material certificates and test reports?
A> Yes, as an ISO9001-certified manufacturer, we provide comprehensive documentation packages. This can include material test reports (MTR), certificate of conformity, and pressure test certificates as standard. Additional certification for marine classification societies can be arranged. -
Q: How do you ensure the valve's performance in high-vibration marine environments?
A> The valve features a robust stem design with anti-vibration features, such as a blowout-proof stem and multiple stem sealing points. The internal components are securely retained to prevent movement. These design elements collectively ensure stable operation despite shipboard vibrations. -
Q: Can you supply larger or smaller sizes for other points in the scrubber system?
A> Certainly. While this listing focuses on DN150, we manufacture a full range of marine ball valves from DN50 (2") up to DN300 (12") and beyond. We can provide a consistent valve solution across your entire scrubber system piping. -
Q: What kind of after-sales support do you offer?
A> We provide technical support for installation and operation, and we maintain an inventory of common spare parts like seals and gaskets for quick turnaround on maintenance needs. Our products are exported globally, with support channels available in our main markets.
