Multiquip 42613-01 Relief Valve - OEM Replacement Part for Hydraulic Trowels

This relief valve protects the hydraulic system in your Multiquip ride-on trowel by preventing excessive pressure buildup that could damage pumps, motors, and other critical components. The relief valve automatically opens when system pressure exceeds safe operating limits, diverting hydraulic fluid back to the reservoir and ensuring consistent performance during blade pitch adjustments and steering operations.

The STX6H trowel utilizes a 45cc mechanical piston Rex Roth hydraulic system that requires proper pressure regulation for reliable operation. This relief valve works in conjunction with the machine's hydraulic drive and steering components to maintain optimal pressure during setup, calibration, and field operation. Regular inspection of the relief valve is recommended during secondary hydraulic fill procedures and when performing machine pressure adjustments as outlined in the HTX6H/STX6H setup and calibration manual.
