The valve uses a linear force motor to drive the spool directly and to conduct the closed loop control through a displacement sensor which mounted at the other end of the spool as the feedback signal input drover, so as to achieve the precise displacement control spool.
Compared with the traditional proportional valve, the servo valve has the characteristics of high control precision, fast dynamic response speed and strong anti-pollution ability,
As a precise and reliable testing machine accessory, it can fully meet the control performance requirements of the high grade electro-hydraulic servo material testing machine.
