As a professional manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve is proud to present our specialized 304 Stainless Steel Marine Gate Valve, engineered for the demanding environments of desulfurization towers. Our valves are designed to offer reliable shut-off, superior corrosion resistance, and long-term performance in critical flue gas desulfurization (FGD) applications. With an annual export value reflecting our global reach and trust from clients across continents, we deliver products that meet stringent international standards for marine and industrial use.
Core Features & Technical Advantages:
- Superior Corrosion Resistance: Constructed from premium 304 stainless steel, this gate valve excels in resisting the corrosive agents commonly found in desulfurization processes, such as sulfur oxides, chlorides, and slurry mixtures, ensuring extended service life.
- Robust Pressure & Size Range: Available in a comprehensive range from DN50 to DN200 and pressure classes from PN10 to PN40, providing flexibility for various pipeline specifications within your FGD system.
- Flanged End Design: The flanged connection ensures a secure, leak-proof seal that is easy to install, maintain, and integrate into existing piping networks, minimizing downtime.
- Bi-Directional Flow: The valve design allows for flow in either direction, simplifying installation and providing operational flexibility.
- Reliable Sealing Performance: We offer options for resilient (soft) seats for bubble-tight shut-off or metal-to-metal seats for higher temperature applications, catering to specific process requirements.
- Durable Stem & Packing: The stem is designed for smooth operation with minimal friction, and high-quality packing material ensures effective stem sealing, preventing external leakage.

Frequently Asked Questions (FAQ):
-
Q: Why is 304 stainless steel recommended for desulfurization tower valves?
A: 304 stainless steel offers excellent resistance to a wide range of corrosive media present in FGD systems, including acidic slurries and oxidizing atmospheres, making it a cost-effective and durable choice for these applications. -
Q: Can this valve handle abrasive slurry flows?
A: While 304 SS provides good corrosion resistance, for highly abrasive slurries, we recommend discussing optional hardened trim materials or specific design modifications to extend service life. -
Q: Are the flanges drilled according to specific standards?
A: Yes. We can manufacture flanges to common international standards such as ANSI, DIN, JIS, or GB. Please specify your required flange standard and facing (RF, FF) when ordering. -
Q: Is the valve suitable for both on/off and throttling service?
A: Gate valves are primarily designed for isolation (fully open or fully closed). Using them for frequent throttling can cause seat and disc erosion. We recommend using them strictly for on/off service. -
Q: What types of operators are available?
A: The standard configuration is a handwheel. For larger sizes (typically DN150 and above) or high-pressure applications, a gearbox operator is available as an option to reduce required operating torque. -
Q: Do you offer fire-safe design versions?
A: Fire-safe designs per API 607/API 6FA standards are available upon request. Please indicate this requirement in your inquiry. -
Q: What is the lead time for an order?
A: Lead time depends on order quantity and specifications. Standard sizes are often available from stock, while customized orders typically require 4-6 weeks. We provide accurate timelines upon order confirmation. -
Q: What documentation is provided with the valves?
A: We provide a material test certificate (MTC), product manual, and packing list. Third-party inspection reports (e.g., DNV, BV) can be arranged if required.
