In an arrangement and method for adjusting an electromatic gas change valve including: an opening and a closing magnet for operating a valve member of the gas change valve; an armature disposed between the opening and closing magnets and operative for movement with the valve member; and an upper and a lower valve spring engaging the valve member and arranged in opposition to each other under pretension so as to hold the valve member and the armature in an equilibrium position, adjustment means are provided for adjusting the equilibrium position during valve operation wherein the current consumption values of the opening and closing magnets over time are measured and integrals thereof are formed in an evaluation unit and the adjustment means are adjusted until the integrals reach a predetermined value corresponding to the desired equilibrium position.
