Title:
CONTROL CIRCUIT OF PROPORTIONAL VALVE USING MAINS-POWER VOLTAGE
Document Type and Number:
Japanese Patent JPH06300162
Kind Code:
A
Abstract:
PURPOSE: To provide a control circuit of a proportional valve for shortening a response time of the proportional valve and eliminating a DC low voltage power supply required conventionally.
CONSTITUTION: In a proportional control valve 10, where an output is proportional to an electrical input signal, preferably operated by a proportional valve solenoid 1 suited to be controlled by a control signal proportional to a voltage or a current, the proportional valve solenoid 1 is directly controlled by a high voltage, or a rectified mains power voltage and a control circuit 60 is secured not to exceed the maximum current value so that the coil of the proportional valve solenoid is prevented from being overload.
