Abstract: The present invention provides a check device and a check valve equipped with the check device. The check device is made of a hard plastic with slight flexibility to be mounted in a check valve with an annular wall and an opening. The check device has a separating rib, an inner plate and an outer plate on opposite ends of the separating rib. The inner plate has several bores and a first contact face to touch a side of the wall, and the outer plate has a first contact face to touch an opposite side of the wall. A flow is cut off when the first contact face of the inner plate presses the first side of the wall, and a flow runs through the check device when a second contact of the outer plate presses a second side of the wall of the base.
