This illustration show Volvo EC330B pump flow control.

Volvo EC360B 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.
