Multiquip 42831 Valve LH w/ Switch Assembly - OEM Replacement Part

This left-hand valve with integrated switch assembly controls critical hydraulic functions in Multiquip ride-on trowel machines, enabling precise steering and blade pitch control during concrete finishing operations. The valve assembly works in conjunction with the steering pressure system, which operates at 300-600 PSI during full operating RPM conditions. This component is essential for maintaining proper trowel speed adjustment and zero stroke position calibration required during machine setup procedures.

During routine maintenance and calibration, technicians must verify steering pressure at the port using proper gauging equipment while the machine runs at full operating RPM. The valve assembly plays a key role in maintaining the precise trowel speeds of 160 ± 3 RPM for HTX6H models and 130 ± 3 RPM for STX6H models. Proper functioning of this valve is critical for stroke sensor calibration and ensuring blade pitch control remains within acceptable drift limits (3/16" maximum over 3 hours).

Compatible models:

• HTX6H Ride-On Trowel
• STX6H Ride-On Trowel
