SOLENOID PROPORTIONAL VALVE FLUID SYSTEM AND CONSTRUCTION MACHINERY
The present invention provides an electronic proportional valve capable of simplifying and miniaturizing a structure for electrically controlling, a fluid system using the electronic proportional valve, and a construction machine. According to the present invention, the electronic proportional valve (150) comprises: a valve unit (10); and a driving device unit (20) for driving the valve unit (10) according to a driving current. The driving device unit (20) includes: a detection part (170) which detects information about the state of at least one of the valve unit (10) and the driving device unit (20); and a control part (200) for controlling the driving current based on the detection result of the detection part (170).
전자 비례 밸브(150)는, 밸브부(10)와, 밸브부(10)를 구동 전류에 따라 구동하는 구동 장치부(20)를 구비한다. 구동 장치부(20)는, 밸브부(10) 및 구동 장치부(20) 중 적어도 어느 한쪽의 상태에 관한 정보를 검출하는 검출부(170)와, 검출부(170)의 검출 결과에 기초하여 구동 전류를 제어하는 제어부(200)를 구비한다.
