摘要： To provide a regulating valve whose stability of an operation is high,a regulating valve is disclosed that includes a valve box in which a first flow channel and a second flow channel are formed, a cage having a first throttle portion provided in a boundary between the first flow channel and the second flow channel, a plug head having a second throttle portion slidably inserted into an inside of the cage, and a guide ring slidably holding a plug guide holding the plug head. In a closed state of the regulating valve, a distance between a through-hole of the first throttle portion and an end portion of the plug head on the other end side is shorter than a distance between a through-hole of the second throttle portion and an end portion of the cage on the opened one end side.
