As a leading manufacturer with ISO9001-certified production, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our premium DIN 3352 Pneumatic Gate Valve. Engineered for reliability in demanding industrial applications, this valve combines robust construction with precise pneumatic actuation for superior flow control. We understand that downtime is costly, which is why our valves are designed for long service life and minimal maintenance, backed by our comprehensive technical support to ensure your operations run smoothly.
This valve is engineered to meet the stringent requirements of the DIN 3352 standard, ensuring interchangeability, dimensional accuracy, and performance reliability across global industrial systems. Its design prioritizes durability and operational efficiency in controlling the flow of liquids, gases, and steam.
Core Features & Technical Advantages:
- Robust & Durable Construction: The valve body is typically manufactured from high-grade materials like cast iron, ductile iron, or stainless steel (A216 WCB, CF8, etc.), offering excellent resistance to pressure, corrosion, and mechanical stress.
- Precise Pneumatic Actuation: Equipped with a double-acting or spring-return pneumatic actuator, providing fast, reliable, and powerful opening/closing action. The actuator allows for remote and automated control, integrating seamlessly into PLC systems.
- Bubble-Tight Sealing: Features a wedge gate design with precision-machined seats. Seat materials like PTFE (for general service) or hardened stainless steel (for high-temperature/pressure) ensure a bubble-tight shut-off, minimizing leakage and product loss.
- Low Operating Torque & Easy Maintenance: The streamlined gate design reduces friction during operation, lowering the required actuator torque and energy consumption. A modular design allows for easy inspection and replacement of internal parts like the gate, seat, and stem packing.
-
Versatile Application Range: Suitable for a wide spectrum of media including water, compressed air, oil, natural gas, steam, and various non-corrosive chemicals. It is a cornerstone component in industries such as:
- Water & Wastewater Treatment
- Oil & Gas Pipelines
- Chemical & Petrochemical Processing
- Power Generation (coal, gas, nuclear)
- Pharmaceutical & Food Processing (with appropriate material grades)
- Marine & Shipbuilding

Frequently Asked Questions (FAQ)
Q1: What does "DIN 3352 compliant" mean for my application?
A1: Compliance with DIN 3352 ensures the valve's face-to-face dimensions, pressure ratings, and testing procedures meet a recognized German industrial standard. This guarantees dimensional interchangeability with other valves built to the same standard, simplifies installation, and provides a benchmark for performance reliability in European and global projects.
Q2: Can this valve be used with steam or high-temperature fluids?
A2: Yes, it can. For standard temperatures up to 150°C, PTFE seats are suitable. For higher temperature applications involving steam or hot oil (up to 400°C), we recommend specifying a version with metal seats (e.g., stainless steel or Stellite) and appropriate body/stem materials to ensure integrity and longevity.
Q3: What is included in the "Technical Support" mentioned?
A3: Our technical support encompasses pre-sales consultation to help you select the correct valve specification, detailed installation and operation manuals, troubleshooting guidance, and after-sales support for maintenance queries. We can also provide CAD drawings and documentation for system integration.
Q4: Are alternative flange standards like ANSI or JIS available?
A4: Absolutely. While the valve design conforms to DIN 3352, we can manufacture it with flanges drilled to other common standards such as ANSI B16.5 or JIS B2220 upon request. Please specify your required flange standard when inquiring.
Q5: What are the available options for the pneumatic actuator?
A5: We offer both double-acting (air to open, air to close) and spring-return (fail-safe) actuators. Options include different torque outputs, NAMUR interface for easy attachment of pilot valves, integrated solenoid valves, limit switches to signal valve position, and manual override mechanisms for emergency operation.
Q6: How is the valve tested before shipment?
A6: Each valve undergoes rigorous testing, which typically includes a shell test (body pressure test) and a seat leak test (closure test) per DIN 3352 or other relevant standards. Test certificates can be provided as part of the documentation package.
Q7: What is the typical lead time for an order?
A7: Lead time depends on the valve size, material, and quantity. For standard configurations in common sizes, we often have stock or can deliver within 15-30 days. For large diameters, special materials, or large batches, production time may be 30-60 days. We provide accurate lead time estimates with every quotation.
Q8: Do you offer customization for specific project needs?
A8: Yes, customization is a key part of our service. We can work with you on special material grades, coatings (e.g., epoxy, galvanized), specific actuator accessories, painting colors, and packaging requirements to meet the exact demands of your project.
