Kobelco SK200-6 Proportional Solenoid Valve YN35V00004F1 KDRDE5K-20/30C12A-111 24V Hydraulic

Description

The YN35V00004F1 proportional solenoid valve (KDRDE5K-20/30C12A-111) serves as a critical hydraulic control component for Kobelco SK200-6 excavator models, representing Kobelco’s proven proportional valve technology in the popular SK200 series. This 24V valve utilizes proportional technology to deliver variable hydraulic flow regulation based on electronic control signals from the machine’s computer system. The SK200-6 series incorporates advanced hydraulic systems featuring independent closed-center circuits that require precisely calibrated proportional components for optimal efficiency and productivity. The valve controls multiple hydraulic functions including implement flow modulation for boom, arm, and bucket operations, swing motor control for smooth controlled rotation, and travel system regulation for variable speed across different ground conditions. Engineered with premium materials and precision manufacturing processes, this valve provides stable performance across varying operating temperatures and pressure conditions encountered in construction applications. The electromagnetic coil assembly delivers consistent and reliable response characteristics for smooth machine operation, while precision-machined spools and passages ensure accurate flow control throughout the valve’s service life. This replacement valve directly swaps with YN35V00004F1 and KDRDE5K-20/30C12A-111, making it ideal for restoring hydraulic system performance on SK200-6 excavators showing proportional valve wear symptoms.
