Multiquip 45548-SK Valve Driver Programmed - OEM Replacement Part for Hydraulic Trowels

The valve driver programmed controls the precise hydraulic flow regulation in Multiquip's hydrostatic drive system, managing the servo-controlled pump operation that powers the trowel rotors. This electronic control component is essential for maintaining the proportional control that allows smooth blade speed adjustment and optimal finishing performance on concrete slabs.

Designed specifically for Multiquip's fully hydrostatic 6-foot ride-on trowels, this programmed valve driver works in conjunction with the Poclain pump and Parker drive motors to eliminate wear on belts, clutches, and driveline components while ensuring efficient power transfer. The valve driver's programming coordinates with the electric linear actuators that control blade pitch, enabling precision adjustments during floating and finishing operations. Symptoms of valve driver failure include erratic rotor speed control, loss of proportional hydraulic response, inability to adjust blade pitch smoothly, or complete loss of hydraulic drive function.

This valve driver is a critical component in the hydraulic control system that enables the LD6 series to achieve performance levels unmatched by traditional mechanical drive systems, maintaining maximum rotor speeds while reducing maintenance costs.

Compatible with the following Multiquip models:

• LD6
