Servo Valve J761-003A have been upgraded

Date:2021/3/4 14:08:47 Visits: Author:Dongfang YOYIK Engineering Co; Ltd,

 servo valve j761 has internal spool position electric feedback. Compared with the proportional electromagnet which can only produce one-way driving force, the permanent magnet linear force motor can directly drive the spool in two directions, and the centering spring acts on the spool to make it reset. The position feedback and pulse width modulation circuit of the valve core are all integrated in the valve. The DDV valve has high resolution and excellent control performance due to the linear force motor with valve core position feedback and large driving force.
