The present invention relates to an air automation valve operation angle setting device, and more specifically, to a memory device in the data area of the program logic control, so as to reduce the working time and improve convenience by eliminating a separate angle setting when changing a mold. will be.;An encoder 10 for detecting a slide angle, an angle sequence A for outputting a side angle detected by the encoder 10 as a BCD signal, and a BCE signal converted by the angle sequence A 7-segment (S) to display the set angle, DIP.switch (D, D1) to set the angle, and program logic controller (PLC) (B) to store BCD signal input and data for each mold. The slide angle is processed in PLC by using BCD signal, and angle data is stored in PLC for each mold, and the angle is automatically converted when the mold number is selected, and the set angle is displayed by 7-segment. Reduced mold replacement time due to the lack of setting, and simple design due to the absence of a separate encoder and rotary chem switch, resulting in cost savings and problems due to the inability of the operator to change the angle arbitrarily during press operation. The design of new useful to get the effect of blocking possession.
