The invention relates to an electromagnetic proportion in an automotive transmission pressure regulating valve (1), which has at least one magnetic element (2), a hydraulic unit (3) and a magnetic element (2) and hydraulic parts (3) between the effective spring element connected (4) among them,, the magnetic element (2) comprising at least one coil (5), an armature (6) and an armature (7), tied root hydraulic parts (3) by at least one first closure element (8) and a second closure element (9). Preferably the first closure element (8) to form a flat seat (10), second (9) to form a closure member (11), which can be set by the push rod (12) the closing element (8, 9) to open and / or close. According to the invention, not to the valve (1) in the case of electricity, second (9) closed and the closure elements overlap (*) is greater than the valve (1) rated width (NW) of 1/7, second higher than the closed surface (A2) with corresponding to two times the overlap (*) the diameter of the round face. Also, the push rod (12) (s) is less than the diameter of the orifice (21) diameter (b) of 0.7 times.
