Product Details

Product Description:

Check valves serve a number of special applications where the medium is only allowed to flow in one direction and the other direction is not permeable, which is difficult to achieve with other valves in the traditional sense. The check valve is an automatic valve that prevents media from flowing back into the system (backflow prevention). Practical applications include preventing media from flowing back into the pipeline or pump. The valve opens when the fluid medium force acts positively on the flap or ball, and when the medium stops flowing or reverse flows, the flap or ball is reset to close the valve. The check valve can be installed in a pipeline that flows horizontally or upwards.
