Chapter 7 Basic Hydraulic Cireuits 7.1.3 Pressure-reducing circuits The function:Used to drop a stable branch circuit pressure below the normal operating pressure of system. Usually a fixed pressure-reducing valve is installed to a branch circuit such as Fig.7-3a.Fig.7-3b is a two-stage pressure-reducing circuit To ensure a stable working speed,the lowest pressure should not be less than 0.5MPa,and the highest setting pressure should be at least less than 0.5MPa of the system pressure.When the actuator elements speed in a reducing-circuit needs to be regulated,the speed-regulating valve should be installed in the latter of the reducing-valve in order to avoid the affection of speed during the working.
