Abstract

PURPOSE: To prevent an accident of discharging fluid from a motor valve by providing a total closure compensating switch in parallel with a total closure detecting switch in a closing direction operating circuit of a device for driving and controlling a motor valve and imparting a complete closure action via a torque seating type based on the variation of a closing torque value to the device.
CONSTITUTION: A total closure compensating switch 19 is connected in parallel with a total closure detecting switch 4 in a closing direction operating circuit 2 of a device for driving and controlling a motor valve, and set at higher operating torque value than the closing torque value of the motor valve. Even if the switch 4 is accordingly opened at predetermined total closure position, the circuit 2 remains closed due to the insertion of the total closure compensating switch 19 to thus continue the closing operation of the motor valve.
