Double disc check valves can be used in drainage pipelines for clean water, sewage, seawater, and other media. They can prevent media backflow and effectively limit destructive water hammer, ensuring the safety of pipeline use. It is not suitable for media containing solid particles and high viscosity.

The double disc check valve has the characteristics of novel structure, small volume, light weight, low fluid resistance, reliable sealing, smooth opening and closing, wear resistance, long service life, oil pressure, slow closing not affected by the medium, and good energy-saving effect. It has been widely promoted and applied in various industries such as industry and urban construction, and has responded well.

Double disc check valve refers to a valve that automatically opens and closes the valve disc based on the flow of the medium itself, used to prevent medium backflow. Its main function is to prevent medium backflow, prevent pump and drive motor reversal, and discharge the container medium. Check valves can also be used to supply pipelines to auxiliary systems where the pressure may rise above the system pressure.

 

 

 

 

Compared with other types of check valves, the structural length of double disc check valves is only about a quarter of that of flange check valves, making them more suitable for use in pipelines with limited space. Compared to other check valves, they are smaller in size, lighter in weight, and more convenient to install, disassemble, and maintain in pipelines. Two valve plates have fast closing speed and low water hammer pressure; The short opening and closing stroke has little impact on the valve plate. Usually, the flow channel has low fluid resistance, sensitive valve opening and closing, and good sealing performance. The butterfly check valve has a simple and compact structural diagram, beautiful appearance, and special casting and painting process, with a long service life and good stability.
