Product details

Micro resistance slow closing butterfly check valve is an advanced valve product mainly used at the outlet of water pumps in industrial water supply and sewage treatment plants to prevent backflow of media in the pipeline network and automatically eliminate destructive water hammer, ensuring the normal operation and safety of water pumps and pipelines. This type of valve has the characteristics of novel structure, small volume, light weight, low fluid resistance, reliable sealing, smooth opening and closing, wear resistance, and long service life

Working principle

The working principle of the micro resistance slow closing butterfly check valve is to smoothly push open the two valve discs through the thrust of the inlet medium. When the pressure of the inlet medium drops below the outlet pressure, the valve disc automatically closes under the action of the spring and medium reflux. However, due to the extended position of the piston rod, it cannot fully close against the valve disc, leaving about 20% of the area for the medium to pass through, thereby eliminating water hammer

Matters needing attention

When installing a micro resistance slow closing butterfly check valve, it is necessary to ensure that the direction of the valve is consistent with the direction of the medium flow to ensure the correct operation of the valve. In addition, the sealing performance of the valve and the wear of mechanical components should be regularly checked, and maintenance and replacement should be carried out in a timely manner to maintain the optimal performance of the valve and extend its service life

Finally, PVC pipe, HDPE pipe, and PPR pipe commonly used plastic pipeline materials, each with different physical and chemical properties. Micro resistance slow closing butterfly check valve is a specially designed valve aimed at controlling fluid flow and reducing water hammer effects. Micro resistance slow closing butterfly check valve is suitable for drainage pipelines of various media, including clean water, sewage, and seawater. This indicates compatibility with PVC water pipe, HDPE water pipe, and PPR water pipe, as these plastic pipe materials are typically used to transport similar media.
