DIN Swing Check Valve
Overview
The DIN Swing Check Valve is an automatic check valve designed and manufactured in strict compliance with the German Industrial Standards (DIN), featuring a swing-type structure. The valve body is typically constructed from materials such as cast iron, cast steel, or stainless steel, with its design conforming to DIN series standards (e.g., DIN 3354). The valve opens as the forward flow of the medium rotates the disc around its pivot and automatically closes under the combined action of the disc's own weight and reverse pressure.This valve can be installed either horizontally or vertically, offering low flow resistance and flexible operation. It is suitable for applications involving water, steam, oil, and various industrial media. Widely used in chemical, energy, water treatment, and other industries within DIN-compliant pipeline systems, it serves as a universal standard solution for preventing medium backflow.
Features
1. Strict DIN Standards Compliance
The entire process of design, manufacturing, and inspection follows DIN EN 12266 and other relevant standards, ensuring full compatibility with German-standard pipeline systems in terms of pressure ratings, structural dimensions, flange connections, and material requirements.
2. Low-Pressure Loss Swing Design
When open, the disc fully swings away from the flow path, resulting in minimal fluid resistance and low-pressure loss, making it particularly suitable for systems with strict energy consumption requirements.
3. Flexible Installation and Reliable Sealing
The valve can be installed horizontally or vertically (with medium flow direction from bottom to top), offering broad applicability. The disc and seat are precisely matched to ensure rapid and tight closure.
4. Robust Structure and Long Service Life
The durable hinge mechanism ensures smooth disc movement, withstands certain water hammer impacts, and provides extended operational life.
5. Easy Maintenance and Strong Versatility
The simple and intuitive internal structure facilitates inspection and maintenance. As a universal component in the DIN system, it simplifies procurement and replacement in European-standard projects.
