What is a proportional valve?

What is a proportional valve? The so-called proportional valve is a kind of according to the input signal continuously and proportionally control the hydraulic system pressure and flow valve. Control valves commonly used in hydraulic systems are often of a switch-controlled nature. Their function is to allow a hydraulic element to be connected to or disconnected from the hydraulic system, or to perform simple oil circuit switching, etc., without continuous control. Servo valves must be used if the hydraulic system's parameters are to be continuously controlled, but servo valves are expensive. The proportional valve hydraulic system parameters can be continuous and proportional control. Compared with the servo valve, it has the advantages of simple structure, low cost and good universality. Proportional valve in the composition of the ordinary pressure valve, flow valve and the control valve into the proportion of the proportion of electromagnet, with the proportional solenoid to change the suction valve parameters for proportional control.
