The 2112092 / 3514 12V Solenoid Valve is an electro-hydraulic control component used in SK series excavators, responsible for managing pilot oil flow to control various hydraulic functions such as boom, arm, bucket, swing, or travel operations. This solenoid valve operates on a 12-volt DC supply and features a compact, sealed coil assembly that provides rapid response to electronic control signals, ensuring precise and smooth machine movements under demanding working 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 sluggish or erratic hydraulic response, loss of function in specific circuits, intermittent operation, or the valve remaining stuck in one position.
