As a leading manufacturer with ISO9001-certified production systems, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our premium DIN 3352 Pneumatic Gate Valve. Engineered for reliability in demanding industrial environments, this valve combines robust construction with precise pneumatic actuation to deliver superior flow control and isolation. With an annual export value reaching US$1.5 million and a strong presence across global markets including North America, Europe, and Southeast Asia, we have built a reputation for quality that is backed by a comprehensive 2-year warranty and a detailed Mill Test Report (MTR) for traceability. This product is designed to meet the high standards of international projects requiring dependable, automated valve solutions.
Our DIN 3352 Pneumatic Gate Valve is a cornerstone for efficient pipeline management. Its design and features offer significant advantages:
- Robust Construction & Materials: The valve body is typically crafted from high-grade carbon steel (WCB) or stainless steel (CF8/CF8M), selected for its excellent corrosion resistance and mechanical strength, ensuring long service life even under high-pressure conditions.
- Precise Pneumatic Actuation: Equipped with a double-acting or spring-return pneumatic actuator, the valve ensures quick, reliable, and fail-safe operation. This allows for remote or automated control, integrating seamlessly into modern SCADA or PLC systems, enhancing operational safety and reducing manual labor.
- Superior Sealing Performance: Available with either a metal seat for high-temperature applications or an optional soft seat (such as PTFE) for bubble-tight shut-off in lower temperature services, minimizing leakage and ensuring process integrity.
- Compliance & Traceability: Manufactured in compliance with DIN 3352 standards for flanged connections, ensuring dimensional interchangeability. Each valve is accompanied by a Mill Test Report, providing full material traceability and verifying chemical and mechanical properties, which is crucial for quality assurance in critical applications.
- Versatile Application Range: Ideal for on/off and isolation services in a wide array of industries including water treatment, oil & gas, chemical processing, power generation, and marine applications. Its design suits both clean and abrasive media.

Frequently Asked Questions (FAQ)
-
Q: What is the primary advantage of a pneumatic actuator over a manual one for this gate valve?
A: The pneumatic actuator enables remote, automated, or rapid operation, which is essential for processes requiring frequent cycling, integration into control systems, or operation in inaccessible or hazardous locations. It significantly improves operational safety and efficiency. -
Q: Can this valve be used for throttling or flow control applications?
A: Gate valves are primarily designed for isolation (fully open or fully closed). Using them for throttling can cause vibration, wire drawing on the seat, and premature wear. For flow control, a different valve type like a globe or control valve is recommended. -
Q: What does the Mill Test Report (MTR) include, and why is it important?
A: The MTR is a certificate from the material mill that details the chemical composition, mechanical properties (tensile strength, yield strength), heat treatment, and test results of the raw materials used (e.g., castings, forgings). It is a critical document for quality traceability, especially in regulated industries like oil & gas, power, and chemical processing. -
Q: Are customization options available for the actuator or valve trim?
A: Yes. We offer customization such as different actuator brands (upon request), specific air supply pressures, fail-safe positions (fail-open or fail-close), limit switches, solenoid valves, and positioners. Valve trim materials can also be selected based on your media and temperature. -
Q: How does the DIN 3352 standard benefit me as an end-user?
A: DIN 3352 specifies the face-to-face dimensions, flange dimensions, and pressure-temperature ratings for flanged gate valves. This standardization ensures that our valve is dimensionally interchangeable with other valves built to the same standard, simplifying replacement, maintenance, and system design. -
Q: What is the typical lead time for an order of these valves?
A: Lead times vary based on size, material, and order quantity. Standard configurations typically have shorter lead times. Please contact our sales team with your specific requirements for an accurate production and delivery schedule. -
Q: Do you provide support for installation and maintenance?
A: We provide detailed installation and operation manuals with each valve. For more complex projects, technical support and guidance are available upon request to ensure optimal performance. -
Q: Is the 2-year warranty valid globally?
A: Yes, our standard 2-year warranty covers manufacturing defects and applies to all our products shipped to our main markets worldwide, subject to proper installation, operation, and maintenance as per our guidelines.
