Pump flow control
At job site, customer uses various kind of optional attachment like hammer, shear etc. Every attachment
has their unique operating specification especially in flow. Our machine can satisfy this request by using
flow control switch and flow control proportional valve.
1. When operator adjust flow control switch, display automatically shows the flow value at the present
engine rpm.
2. When operator uses the option attachment, the pilot pressure switch will be activated. V-ECU receives
this signal and then start to controls the flow control valve according to flow control switch position. If the
pilot switch is off position, there is no output current from V-ECU. That means flow control function is
engaged only during the working of optional attachment.
