AI Overview
Komatsu pump flow control solenoid valves (e.g., 702-21-61500, 203-60-56180) are critical electro-hydraulic components that regulate hydraulic fluid pressure and flow to actuators (boom, arm, bucket) on excavators, loaders, and dozers, generally costing around
. They ensure smooth operation, and failure often causes erratic performance, low hydraulic pressure, or machine downtime.

What is the difference between a flow control valve and a solenoid valve?
Control valves are built to regulate, or throttle, the flow of fluids and gases. Solenoid valves are built for speed, snapping a flow path fully open or fully closed in an instant. They do two completely different jobs, and understanding that is key to good process design.Dec 31, 2025
