Abstract
PURPOSE: To provide sure control of an electric valve, by fitting a radio communication device for wireless control of the valve movement.
CONSTITUTION: An instruction radio wave emitted from a transmitter is received by a receiver in a casing of an electric drive unit 2. Upon receiving the radio wave, a control switch CS is turned to a position B by the receiver to actuate a motor M for driving a valve body 1 to the position of control valve. The control position is detected by a position detector composed of a dauser disc 12 and photoelectric sensers 13, 15. A point of contact X2 is opened when a through hole 17a is positioned to the photoelectric senser 13 and the motor M is interrupted. When an instruction wave is emitted from the fransmitter for shifting the control switch CS to a position A, another point of contact X1 is closed, then the motor M is actuated to drive the valve body 1 to the next control position. Thus the valve can surely be controlled.
