The invention provides an electrically operated valve which can control a flow rate precisely at a small flow rate distributing time and can circulate a fluid so as to prevent a pressure loss as much as possible at a large flow rate distributing time without an increase of a working and assembling cost. A movable valve seat body forming a main valve port for forming a small flow rate flow path extending from a first inlet and outlet to a second inlet and outlet is arranged between a valve chamber and a lower chamber. The movable valve seat body is structured such that its lower portion is slidably fitted and inserted to the lower chamber, and such as to serve as a float type check valve body for opening and blocking a large flow rate flow path extending from the second inlet and outlet to the first inlet and outlet.
