Abstract
[Object] Provided is a control valve capable of ensuring controllability in both flows without increasing the number of parts.[Solving Means] A plurality of differential pressure valves 50, 60, 70, and 80 are disposed inside a valve body 10 so that a fluid pressure acting on a main valve body 20 disposed inside a main valve chamber 13 becomes the same in a flow of both directions including one direction from a first inlet/outlet 11 to a second inlet/outlet 12 through the main valve chamber 13 and the other direction from the second inlet/outlet 12 to the first inlet/outlet 11 through the main valve chamber 13.
