Bus control pressure closed-loop proportional relief valve, used to control the working pressure of the hydraulic system, and can play a protective role in the actuator. On the basis of the traditional open-loop control proportional pressure valve, the pressure feedback is added to achieve closed-loop control, and the pressure control precision and response speed are improved. Optional with bus interface, bus control pressure precision is higher, the pressure output is linear, the pressure accuracy is determined by the accuracy of the pressure sensor. Suitable for die forging press, ceramic pressure and other high precision pressure control occasions.
