YN35V00048F1 Proportional Hydraulic Pump Solenoid Valve for Kobelco SK200-8 SK250-8 SK260-8

YN35V00048F1 Hydraulic Pump Proportional Solenoid Valve

The YN35V00048F1 proportional solenoid valve is used in the hydraulic pump control system on selected Kobelco excavators. It receives an electrical command and regulates hydraulic control pressure to support proportional pump response during machine operation.

KDRDE5K-31/30C50-122/107 is the corresponding Kawasaki valve reference for this product. Before ordering, compare the complete valve marking, electrical connector, coil orientation, valve body length, sealing grooves and installation position with the existing unit.

Fitment and Hydraulic System Checks

The main confirmed machine references are Kobelco SK200-8, SK250-8 and SK260-8 excavators. Hydraulic pump and valve configurations can vary according to machine serial number and market specification, so the machine model should not be used as the only fitment reference.

Unstable pump output, slow hydraulic response, weak operation or an intermittent solenoid fault can also result from damaged wiring, poor connector contact, incorrect voltage, controller signal problems, contaminated hydraulic oil, abnormal control pressure or internal pump wear. Check both the electrical circuit and hydraulic system before installing the valve.

FAQ

How can I confirm whether YN35V00048F1 fits my excavator?

Provide the machine model, serial number, existing valve number and clear photos of the connector, coil, valve body marking and hydraulic pump installation position.

What should be compared before installation?

Compare the connector shape and pin arrangement, coil direction, valve body dimensions, threaded area, sealing grooves, O-ring position and hydraulic pump mounting location.

What should be checked if hydraulic performance does not improve?

Inspect the wiring harness, connector terminals, control voltage, controller signal, hydraulic oil condition, filters, pump control pressure and internal pump condition. A hydraulic response problem is not always caused by the solenoid valve.

What are the MOQ, lead time and warranty?

The minimum order quantity is one piece, the standard lead time is 7–15 days, and the warranty period is 6 months. Confirm current availability before ordering.
