As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance industrial valves for global pipeline systems. Our DIN 3352 Gate Valve is engineered to deliver reliable shut-off and control for demanding water and oil transportation applications. With an annual export value exceeding US$1 million and a presence in markets across North America, Europe, Asia, and beyond, we combine rigorous manufacturing standards with practical design to offer valves that ensure system integrity, reduce maintenance costs, and enhance operational safety for our clients worldwide.
This gate valve is designed according to the widely recognized DIN 3352 standard, ensuring compatibility and interchangeability in international industrial projects. It features a robust construction suitable for on/off service in pipelines carrying water, oil, and other compatible fluids. The valve's design minimizes pressure drop when fully open, promoting efficient flow and reducing energy consumption.
Key Features & Technical Advantages:
- Rigorous Standard Compliance: Manufactured in strict accordance with DIN 3352 specifications, guaranteeing dimensional accuracy, performance reliability, and ease of installation within standardized pipeline networks.
- Versatile Material Selection: Available in various body materials including ductile iron (for general water service), cast steel (for higher pressure/temperature), and stainless steel (for corrosive environments). This allows customization based on specific fluid media and operating conditions.
- Superior Sealing Performance: Equipped with a wedge gate and precision-machined seats. Options include resilient-seated (for bubble-tight shut-off) or metal-seated (for high-temperature/pressure applications) designs, ensuring long-term leak-proof operation.
- Durable Stem & Packing System: Features a stainless steel stem with anti-blowout design. The gland packing is easily adjustable, providing a reliable seal around the stem and extending service life.
- Multiple Actuation Options: Can be operated manually via a handwheel or ergonomic lever, or automated with gear operators or electric actuators for remote control and integration into SCADA systems.
- Robust Flanged Connections: Standard flanged ends conform to DIN, ANSI, or JIS standards, facilitating secure and leak-free connection to existing pipeline flanges.

Frequently Asked Questions (FAQ)
Q1: What does "DIN 3352" signify for this gate valve?
A1: DIN 3352 is a German industrial standard that specifies the design, dimensions, pressure ratings, and testing requirements for gate valves. Compliance ensures the valve meets recognized international criteria for performance, safety, and interchangeability, which is crucial for engineering and procurement in global projects.
Q2: Can this valve be used for both water and oil services?
A2: Yes, it is designed for industrial water and oil pipeline systems. The specific material selection (e.g., body, seat, stem) should be chosen based on the fluid's properties (e.g., viscosity, corrosiveness, temperature) to ensure optimal performance and longevity. Our technical team can assist in material selection.
Q3: What are the main differences between the available body materials (ductile iron, cast steel, stainless steel)?
A3: Ductile iron offers good strength and corrosion resistance for general water applications at a competitive cost. Cast steel (WCB) provides higher strength and better performance at elevated temperatures and pressures. Stainless steel (CF8/CF8M) is used for corrosive fluids or environments where hygiene is a priority.
Q4: Is a bubble-tight shut-off guaranteed?
A4: Bubble-tight shut-off is achievable primarily with resilient-seated designs, where an elastomer (like EPDM or NBR) is bonded to the wedge. For high-temperature applications requiring metal-seated valves, shut-off is very tight but may not be classified as "bubble-tight." The choice depends on your specific leakage rate requirements.
Q5: Can the valve be automated?
A5: Absolutely. While supplied with a standard handwheel for manual operation, the valve can be fitted with electric actuators or gear operators. We offer various automation options suitable for remote control, frequent operation, or integration into automated process control systems.
Q6: What pressure ratings are available?
A6: Standard pressure ratings include PN10, PN16, and PN25 (metric), corresponding to approximately 10, 16, and 25 bar nominal pressure. An ANSI Class 150 rating is also available. The suitable rating depends on your system's maximum operating pressure.
Q7: What is the typical delivery time for an order?
A7: Delivery time varies based on order quantity, material specifications, and any custom requirements (like actuation). Standard configurations in common sizes often have shorter lead times. We provide reliable shipping from major Chinese ports and can offer estimated timelines upon receipt of your detailed inquiry.
Q8: Do you provide documentation and certifications with the valves?
A8> Yes. Along with the product, we typically provide a test certificate (report) for the batch, material certificates, dimensional drawings, and a manual. As an ISO9001-certified manufacturer, our documentation process is well-established to meet the needs of professional B2B clients.
