Abstract
A flush valve includes a body having an inlet an outlet and a seat between the inlet and the outlet. The seat defines an opening therethrough. A cover is attached to the body. A piston is engageable with the seat and movable within the body and cover to an extent permitted by a stop formed in the body or cover. The piston includes a guide portion extending through the seat opening and downstream of the seat. The guide portion has ribs and a skirt. The axial length of both the ribs and skirt is greater than the available piston travel so the flow passages through the seat opening at all times are defined by the skirt and ribs.
