Hydraulic Pump Solenoid Valve SK200-6 DH220-5 SK200-A6E K3V112 TDDRDE 3K-20/40

Description

This hydraulic pump solenoid valve (3K-20/40 series) is a critical component for hydraulic pump control in Kobelco SK200-6, Hyundai DH220-5, and SK200-A6E series hydraulic excavators equipped with the K3V112 TDDRDE hydraulic pump. The solenoid valve serves as the primary flow control element that manages hydraulic fluid delivery from the pump to the machine implement circuits, directly affecting digging power, swing speed, and travel performance. Designed for the high-pressure demands of these popular mid-size excavator models, the valve features reinforced construction capable of handling system pressures encountered during demanding digging, lifting, and loading operations. The electromagnetic coil assembly provides rapid, reliable switching response that translates operator joystick inputs into immediate hydraulic system reactions, ensuring the responsive machine control essential for productive excavation work. Precision internal passages minimize pressure losses and ensure consistent flow distribution across all hydraulic functions simultaneously. The valve integrates seamlessly with K3V112 series pumps, maintaining proper hydraulic circuit balance and protecting pump components from pressure spikes. This cross-compatible solenoid valve is an essential replacement part for maintaining peak excavator performance and is suitable for both scheduled maintenance and urgent repair needs.
