Cat Hydraulic Proportional Solenoid Valve | Pilot Control & Pressure Reducing Valve for E320 / E315 / E320GC Same-Platform Excavators
Restore precise hydraulic response and eliminate erratic swing, travel, or implement lag on your Cat E320, E315, or E320GC with our hydraulic proportional solenoid valve, a direct OEM-replacement proportional pressure reducing valve engineered for Cat C-series and GC-series same-platform excavators. This excavator main control valve solenoid converts electronic controller signals into accurate pilot oil pressure, delivering smooth, proportional flow and pressure control for boom, arm, bucket, swing, and travel functions. Rated for 12V/24V DC operation, built with a high-permeability solenoid core, precision-wound copper coil, hardened valve spool, and IP67-sealed housing, this proportional electro-hydraulic valve ensures stable current-pressure linearity, zero external leakage, and reliable performance in dusty, wet, and high-vibration job sites. Supplied with cross-reference part numbers, connector & harness options, and full serial-number verification, it's backed by strict ISO 9001 quality control and global technical support — the smart fix for contractors who need dealer-level performance without dealer-level prices.
