Multiquip 43740 Left Hand Valve Assembly with Switch - OEM Replacement Part

This left hand valve assembly with integrated switch controls hydraulic flow direction and speed for the left side rotor assembly on hydraulic drive trowels. The valve regulates pump actuation to ensure balanced trowel operation and precise steering control, critical for achieving uniform concrete finishing across the entire work surface.

On hydraulic trowel systems, the left and right drive motors operate independently through separate valve assemblies. This LH valve assembly directly impacts left-side rotor speed and responsiveness. When valve assemblies malfunction or wear, symptoms include difficulty controlling steering, one spider spinning noticeably faster or slower than the other, or uneven concrete finishing. The integrated switch provides operational feedback to the control system, ensuring proper coordination between hydraulic circuits.

Compatible with the following Multiquip trowel models:

• PRX Series Trowels
• STXDF Series Trowels

Regular inspection of valve assemblies is recommended as part of annual trowel speed calibration procedures. Genuine Multiquip OEM part, sold by an authorized dealer.
