The 419-15-16910 Solenoid Valve is an electro-hydraulic control component used in Komatsu WA200-1, WA250-1, and WA320-1 wheel loaders, responsible for managing pilot oil flow to control transmission clutch engagement or other hydraulic functions such as differential lock or brake release. This solenoid valve operates on a 24-volt DC supply and features a compact, fully sealed coil assembly that provides rapid response to electronic control signals, ensuring smooth gear shifting and reliable machine performance under continuous heavy-load conditions. The internal spool is precision-ground from wear-resistant steel to minimize internal leakage, while high-temperature elastomer seals provide durability in harsh environments. As a direct replacement part, it matches required mounting dimensions, thread types, and flow characteristics for straightforward installation. Typical failure symptoms include harsh or delayed shifting, transmission slipping, loss of specific gears, or intermittent hydraulic function.
