As a leading manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in delivering high-performance industrial valves. Our DIN 3352 Stainless Steel Gate Valve is engineered for demanding applications where reliability and longevity are non-negotiable. We combine robust stainless steel construction with precision manufacturing to offer a valve solution that ensures superior shut-off capability and exceptional corrosion resistance. With an annual export value reaching up to US$1.5 million and a strong presence across global markets from North America to Southeast Asia, we are committed to providing products backed by an extended warranty and comprehensive Mill Test Reports, giving you complete confidence in material traceability and quality assurance.
This gate valve is designed according to the DIN 3352 standard, ensuring compatibility with international piping systems. Its primary function is to provide a tight seal for the complete on/off control of fluid flow. The valve's design minimizes pressure drop when fully open, making it efficient for a wide range of services.
Key Features and Technical Advantages:
- Premium Stainless Steel Body: Constructed from grades like 304 or 316 stainless steel, offering excellent resistance to corrosion, pitting, and oxidation in various aggressive environments, including water, oil, gas, chemical, and steam services.
- DIN 3352 Flanged Design: Ensures easy installation and secure connection to DIN standard flanged piping systems, providing a reliable and leak-proof interface.
- Flexible Seat Options: Available with soft seats (e.g., PTFE) for bubble-tight sealing in lower temperature services or metal seats (Stellite hard-faced) for high-temperature and abrasive applications.
- Extended Stem Design: The rising stem mechanism provides clear visual indication of the valve position (open or closed), enhancing operational safety.
- Multiple Operation Methods: Can be supplied with a standard handwheel for manual operation or equipped with a gearbox for easier operation in high-pressure or large-size applications.
- Robust Pressure Handling: Engineered to withstand a range of pressure classes, commonly PN10, PN16, PN25, and PN40, catering to diverse system requirements.

Frequently Asked Questions (FAQ):
-
Q: What is the significance of the DIN 3352 standard for this gate valve?
A: DIN 3352 is a widely recognized German industrial standard that specifies dimensions, pressure ratings, and testing requirements for flanged gate valves. Valves conforming to this standard ensure interchangeability, reliable performance, and compatibility with piping systems designed to DIN specifications globally. -
Q: Which stainless steel grades are typically used, and how do I choose?
A: Common grades are AISI 304 (general corrosion resistance) and AISI 316 (superior resistance to chlorides and acids). The choice depends on your specific fluid media. Our technical team can advise based on your application's chemical composition, temperature, and concentration. -
Q: What does the "Extended Warranty" cover?
A: Our extended warranty goes beyond standard offerings, covering defects in material and workmanship for a longer period. Specific terms are provided with the purchase agreement, offering added protection against premature failure under normal operating conditions. -
Q: What information is included in the Mill Test Report (MTR)?
A: The MTR is a certified document from the steel mill. It includes crucial data such as the heat number, chemical analysis (content of elements like Cr, Ni, Mo), mechanical properties (tensile strength, yield strength), and compliance statements with relevant material standards, ensuring full material traceability. -
Q: Can this valve be used 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 vibration, seat, and disc erosion, leading to leakage. We recommend using them strictly for on/off applications. -
Q: Are these valves suitable for high-temperature steam applications?
A: Yes, when ordered with a metal seat (e.g., Stellite hard-faced), this valve can handle high-temperature services such as steam. It is critical to specify the maximum temperature and pressure of your steam service during inquiry to ensure the correct material and design selection. -
Q: What are the available port of shipment options?
A: We ship from multiple major Chinese ports including Shanghai, Guangzhou, Hong Kong, and Beijing. This flexibility allows us to optimize shipping routes and costs based on your destination, ensuring timely delivery. -
Q: Do you offer customization for special requirements?
A: Yes, as a manufacturer, we can discuss customization options. This may include special materials, non-standard dimensions, different flange face finishes (RF, FF), or specific painting/packing requirements. Please contact us with your detailed specifications.
