The invention discloses a control system for valves. The control system comprises a first parameter monitoring component, a second parameter monitoring component, a controller and an input device; thefirst parameter monitoring component and the second parameter monitoring component are arranged inside a pipeline; the output end of the first parameter monitoring component and the output end of thesecond parameter monitoring component are connected with the signal input end of the controller; the output end of the controller is connected with the signal input end of each to-be-controlled valve; and the signal output end of the input device is connected with the input end of the controller. According to the control system, the parameter monitoring components, the controller, the input device and each electric valve form a closed-loop negative feedback system, feedback signals of the two parameter monitoring components are selected by the controller, a set value is revised, then controlopening degree signals is o
