Bomag 05546170 Pressure Relief Valve

The Bomag 05546170 Pressure Relief Valve is a genuine OEM component designed for a broad range of Bomag cold milling machines, pavers, tandem rollers, single drum rollers, recyclers/stabilizers, refuse/landfill compactors, and soil compactors. As a direct OEM replacement, this valve is manufactured to the exact specifications required by Bomag equipment, ensuring consistent hydraulic system behavior across every machine it serves. Fitment covers an extensive lineup including BM-series cold milling machines, BF-series pavers, BW-series tandem and single drum rollers, BC-series refuse/landfill and soil compactors, MPH and RS-series recyclers/stabilizers, and the C 825 C single drum roller. Confirm your machine model against the full fitment list before ordering to ensure part number 05546170 is the correct match for your application.

Key Features

• Genuine OEM Hydraulic Precision — manufactured by Bomag to exact cracking-pressure and flow-rate specifications, so the valve opens and closes at the correct system threshold every time
• Direct OEM Replacement — installs in the existing hydraulic circuit port without modification, preserving original line routing and torque specifications
• Broad Cross-Family Fitment — verified for BM-series cold milling machines, BF-series pavers, BW tandem and single drum rollers, BC refuse/landfill and soil compactors, MPH and RS recyclers/stabilizers, and the C 825 C roller, including models such as the BM 2500/75, BF 800 C-3 S 600, BW 213 DH-4, and BC 1172 RB-4
• Protects the Hydraulic System — limits peak pressure spikes that would otherwise damage pumps, motors, cylinders, and hoses, extending the service life of downstream components
• Prevents Costly System Failures — a worn or stuck relief valve causes overheating, erratic actuator response, and catastrophic component damage; replacing it with part number 05546170 restores safe, stable hydraulic operation
• Fuel and Hydraulic System Safety — correct relief-valve calibration is critical to preventing over-pressurization events; using the genuine OEM part ensures the system stays within its designed pressure envelope

A pressure relief valve is a hydraulic safety component that limits the maximum operating pressure within a hydraulic circuit. When system pressure rises above the valve's set threshold — due to a blocked actuator, abrupt load change, or pump surge — the valve opens to divert excess fluid back to the tank, protecting pumps, motors, cylinders, and hoses from over-pressurization damage. When a relief valve fails, either by sticking open or failing to open at the correct pressure, the machine will exhibit symptoms ranging from sluggish or weak hydraulic response to sudden component failures, making timely replacement essential to safe and productive operation.
