Check valve refers to the valve which automatically opens or closes the valve by the flow of the medium itself, and is used to prevent the backflow of the medium.Check valve is a kind of automatic valve, its main function is to prevent medium backflow, pump and drive motor reversal, and container medium discharge.The check valve can also be used to provide a supply line to an auxiliary system where the pressure may rise above the system pressure.Check valve can be divided into swing check valve (rotating according to the center of gravity) and lifting check valve (moving along the axis).  Check valves are designed to allow only medium flow in one direction and prevent reverse flow.Usually the valve operates automatically, and the disc opens under a flow pressure in one direction.When the fluid is flowing in the opposite direction, the pressure of the fluid and the self-aligning disc of the disc act on the seat to cut off the flow.  Check valves of this type include swing check valves and lift check valves.The swing check has a simple hinge mechanism and a door like disc that rests freely against the inclined seat surface.To ensure that the disc reaches the proper position of the seat face each time, the disc is designed in a hinge mechanism so that the disc has enough swing space and allows the disc Product Name Check valve Material Carbon Steel, Stainless Steel, Cast Iton, Ductile Iron OD DN40-900mm Medium water, oil, gas  Process characteristics: Negative pressure vacuum casting technology, specially designed for castings with a large size of 100k or more Process advantage Because of its negative pressure footnote, the casting has less blisters, more product compactness, smooth surface and clear outline. Description of machining parameters: Upper flange: The upper flange link conforms to the national standard 5211 standard and is suitable for various transmission modes of handle, turbine, electric and pneumatic.
