DIN Standard CF3M PN16/PN25 Stainless Steel Flange End Swing Check Valve
Design Features
Swing Type Structure: The valve disc rotates around the axis of the valve seat, with quick opening and closing actions, low fluid resistance, and can effectively prevent the backflow of media.
Full Bore Design: The passage inside the valve body is consistent with the inner diameter of the pipeline, ensuring the smooth flow of media, reducing pressure loss, and improving the overall efficiency of the system.
Strong Corrosion Resistance: The stainless steel of CF3M material has excellent anti-corrosion performance, can resist the erosion of various chemical media, extend the service life of the valve, and reduce maintenance costs.
Flange Connection: The flange connection method conforming to the DIN standard is adopted, making installation and maintenance more convenient and ensuring a reliable connection between the valve and the piping system.
Compliance with International Standards: Its design and manufacture comply with standards such as DIN 3357 and DIN 3202, ensuring the quality and reliability of the product and meeting the engineering specification requirements of different countries and regions.
