A linear solenoid valve actuation device comprises a step wave generating circuit comprising a converting circuit whereby the desired amount of control is computed at a predetermined period of clocks to hold or store the computed value until the next computation and generate a step wave voltage having a value corresponding to the computed value,BALANCING VALVES and a current amplifier circuit for supplying to a linear solenoid valve a current having a value corresponding to the output voltage of the step wave generating circuit, Forged Steel Valvesthereby actuating the linear solenoid valve with a step waveform current. The linear solenoid valve actuation device further comprises a hysteresis elimination circuit for generating a signal having a value corresponding to the frictional force of the sliding portion in the linear solenoid valve and added to or subtracted from the step waveform drive signal, Bellows Seal Valvesand a circuit whereby a pulse signal of a predetermined width is added to the step waveform drive signal when it is increasing and the pulse signal is subtracted from the drive signal when it is decreasing.
