Cast iron dual plate check valve PN16
Dual plate check valve is also known as counter-current valve, reverse check valve, back pressure valve, one-way valve. Such check valve are automatically opened and closed by the force generated by the flow of the medium itself in the pipeline and belong to an automatic valve.
Check valve is to rely on the flow of the medium itself and automatically open and close the disc, used to prevent the medium backflow valve, also known as reverse stop valve, one-way valve, counter-current valve, and back pressure valve. Check valve belongs to an automatic valve, its main function is to prevent medium backflow, prevent pump and drive motor reversal, as well as the media release. A check valve can also be used to supply piping where the pressure may rise to an auxiliary system that exceeds the system pressure. Check valve can be divided into rotary check valve (rotating according to the center of gravity) and lift check valve (moving along the axis).
Application
Dual plate check valve is used for Preventing the back-going of medium in pipelines and equipments,and the pressure of medium will bring the result of opening and closing automatically.When the medium is back-going, valve disc will automatically closed to avoid accidents.
