As a leading manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our DIN 3352 Stainless Steel Gate Valve. Engineered specifically for the demanding environments of shipbuilding and offshore applications, this valve is a cornerstone of our product line, designed to ensure safe, efficient, and long-lasting flow control in critical marine systems. Established in 2016, we have dedicated ourselves to producing industrial valves that meet the highest standards, backed by our ISO9001 certified quality management system. Our annual export value reflects the trust placed in us by clients across the globe, from North America and Europe to Southeast Asia and the Middle East. This gate valve exemplifies our expertise, combining robust construction with precise engineering to deliver superior performance where it matters most.
Constructed from high-grade stainless steel, our DIN 3352 gate valve offers exceptional resistance to corrosion, pitting, and crevice corrosion caused by seawater, brackish water, and harsh offshore atmospheres. The metal-to-metal seat design ensures a tight seal and reliable shut-off even after prolonged periods of operation, making it ideal for isolation services in piping systems. Its robust flanged ends, conforming to international standards, facilitate secure and leak-proof connections, simplifying installation and maintenance procedures onboard vessels and offshore structures.
Key Features & Technical Advantages:
- Superior Corrosion Resistance: Manufactured from stainless steel grades like CF8M (316), providing excellent defense against saltwater corrosion and chemical attack common in marine environments.
- Robust DIN 3352 F4 Design: Complies with the stringent DIN 3352 standard for cast iron and steel gate valves, ensuring dimensional accuracy, mechanical strength, and interchangeability.
- Bidirectional Flow & Tight Shut-off: The wedge design allows for flow in either direction and achieves a bubble-tight seal, crucial for safety in shipboard and offshore applications.
- Extended Service Life: Precision machining, high-quality materials, and rigorous testing result in a valve built for durability and reduced total cost of ownership.
- Versatile Operation: Standard handwheel operation for easy manual control. Options for gearbox operators are available upon request for larger sizes or high-pressure applications.
- Wide Pressure & Temperature Range: Suitable for a broad spectrum of working conditions typically encountered in marine engineering.

Frequently Asked Questions (FAQ)
Q1: What are the main advantages of using a DIN 3352 gate valve in marine applications?
A1: The DIN 3352 standard ensures robust construction, dimensional consistency, and reliable performance. When made from stainless steel, it provides superior corrosion resistance essential for seawater and offshore environments, offering longevity and safety.
Q2: Can this valve be used with other fluids besides water?
A2: Yes, the stainless steel construction makes it suitable for a range of mildly corrosive fluids, oils, and gases commonly found in shipboard systems. However, compatibility for specific aggressive chemicals should be verified upon request.
Q3: What flange standards are available?
A3: We typically manufacture to DIN flanges, but valves can be customized to meet ANSI, JIS, GB, or other international flange standards based on your project specifications and piping requirements.
Q4: Is a gear operator necessary, and is it available?
A4: For larger valve sizes (typically above DN300) or in high-pressure systems where manual operation requires high torque, a gearbox operator is recommended for easier opening and closing. It is available as an optional accessory.
Q5: What is the typical lead time for orders?
A5: Lead times vary based on order quantity, size, and customization. Standard sizes are often available from stock or have shorter production cycles. We provide accurate lead time estimates upon receipt of your inquiry.
Q6: Do you provide documentation like test reports and certificates?
A6: Yes, as an ISO9001 certified manufacturer, we can provide necessary documentation, including material certificates, pressure test reports (per API 598/EN 12266), and inspection reports, which are crucial for marine project approvals.
Q7: How does the metal seat perform compared to soft seats?
A7: Metal seats offer greater durability, higher temperature tolerance, and better resistance to erosion and galling. They are preferred for applications requiring frequent operation, high pressures, or where fire-safe design is a consideration, common in offshore settings.
Q8: What after-sales support do you offer?
A8: We provide technical support for installation and operation. While valves are designed for long life, we can assist with spare parts identification and supply to support maintenance needs, ensuring continued system reliability.
