This relief valve, part number 5100016778, is a hydraulic pressure-limiting component located within the control block, control valve, and hydraulic manifold assemblies, including the RTK82-SC3 and RTL82-SC3 hydraulic distributors on Wacker Neuson trench rollers. Seated inside the hydraulic control circuit, it regulates system pressure by diverting flow when pressure exceeds the set threshold, protecting downstream hydraulic components from overload.
This valve is used across Wacker Neuson's SC3 and SC2 series trench roller platform, spanning both RTK and RTL machine families. If the hydraulic system exhibits sluggish drum movement, erratic directional control response, or excessive heat buildup in the hydraulic circuit, a faulty or worn relief valve is a common source. Replacing this valve restores proper pressure regulation within the control block and hydraulic distributor circuit.
When servicing, refer to the machine's hydraulic schematic and verify the model number, item number, and serial number before ordering, as confirmed by Wacker Neuson service documentation for this platform.
