56D-15-35220 Solenoid Valve | Komatsu Excavator Hydraulic Pilot Valve

Description

The 56D-15-35220 solenoid valve is a hydraulic pilot control valve engineered for Komatsu excavators operating in demanding construction and earthmoving environments. This valve regulates pilot hydraulic pressure that controls the main spool valves for boom, arm, bucket, and swing functions, directly impacting operator feel and machine responsiveness. The 56D-15-35220 is manufactured with a high-durability housing that resists corrosion and mechanical wear from contaminated hydraulic oil. Its solenoid coil operates at 24V DC with IP66-rated encapsulation to protect against dust and water spray in outdoor excavation conditions. The precision-balanced spool design ensures consistent pilot pressure delivery across varying system loads. Compatible with multiple Komatsu PC-series excavator models. Fully interchangeable with part number 56D-15-35220 as a direct bolt-on replacement. All units are individually tested for coil resistance, response time, and pressure holding before dispatch. A cost-effective alternative to OEM pricing for fleet maintenance managers and equipment dealers worldwide.
