Hydraulic Sequential Valve Group  

Hydraulic sequence valve group is a valve group used to control the sequential operation of hydraulic components in a hydraulic system. It consists of multiple hydraulic sequence valves. By combining the working sequences of different valve groups, it realizes the orderly work of multiple hydraulic components in the hydraulic system. Hydraulic sequence valve group usually consists of main valve, auxiliary valve and control valve. The main valve is used to control the working sequence of the main hydraulic components, the auxiliary valve is used to control the working sequence of the auxiliary hydraulic components, and the control valve is used to control the switching of the main valve and the auxiliary valve. The working principle is to control the work of the main valve and auxiliary valve by controlling the switching status of the valve. When the control valve is closed, both the main valve and the auxiliary valve are closed, and the hydraulic components stop working; when…
