An automatic plate valve having a valve seat, a valve guard, a longitudinal axis (L) and a valve element arranged between the valve seat and the valve guard and movable along the longitudinal axis (L). The valve seat includes an end face having with valve seat openings oriented towards the valve guard, and a plurality of passages, which have a fluid-conducting connection to the valve seat openings. The valve element includes sealing element interacting with the valve seat openings. Wherein some of the passages have a different distance to the longitudinal axis in a radial direction (R). The end face of the valve seat including a plurality of grooved recesses, forming valve seat openings, with passages open into the same recess, the passages forming a fluid-conducting connection to the valve seat opening. Some of these passages connected to the valve seat opening have different distances to the longitudinal axis.
