The Bomag 05877066 Pressure Relief Valve is a genuine OEM component designed for a wide range of Bomag refuse/landfill compactors, soil compactors, cold milling machines, and recycler/stabilizers. Sourced directly from Bomag, this pressure relief valve meets the same specifications as the original unit installed at the factory, ensuring an exact fit across compatible machines. This valve fits Bomag BC-series refuse/landfill compactors including the BC 672 RB, BC 772 RB, BC 972 RB, BC 1172 RB, and their generation variants, as well as BC 772 EB-2, BC 672 EB-2, and BC 772 EB-4 soil compactors, BM 500/15 and BM 600/15 cold milling machines, and MPH 121, MPH 122, and MPH 122-2 recycler/stabilizers. Ordering by part number 05877066 ensures you receive the correct valve the first time.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's original pressure rating and flow specifications, so the valve opens and closes at the correct set point without hydraulic drift or chatter
- Direct-Fit Replacement — matches the original port threading, body dimensions, and cracking pressure of the factory valve, dropping into the existing hydraulic circuit without rework
- Broad Bomag Coverage — fits BC-series refuse/landfill and soil compactors (including BC 572 RB-2, BC 672 RB, BC 772 RB, BC 972 RB, and BC 1172 RB families), BM 500/15 and BM 600/15 cold milling machines, and MPH 121, MPH 122, and MPH 122-2 recycler/stabilizers
- Protects the Hydraulic System — a correctly functioning pressure relief valve prevents over-pressurization that can rupture hoses, damage pumps, and cause uncontrolled machine movement; replacing a worn or stuck valve restores proper circuit protection
- Fuel and Hydraulic System Safety — on heavy compaction and milling equipment operating at high hydraulic pressures, a calibrated relief valve is a critical safety component; using a genuine OEM part maintains correct pressure limits and helps protect the operator and surrounding equipment
A pressure relief valve is a hydraulic safety device that limits the maximum pressure within a hydraulic circuit. When system pressure rises above the valve's set point — due to a stalled actuator, overload, or sudden shock load — the valve opens to divert fluid back to the reservoir, protecting hoses, cylinders, pumps, and motors from damage. On heavy equipment such as refuse compactors, cold milling machines, and recycler/stabilizers, hydraulic pressure can spike rapidly during cutting, compacting, or steering maneuvers, making a properly calibrated relief valve essential to safe operation. A valve that is stuck open bleeds off pressure continuously, causing sluggish or weak hydraulic response; one that is stuck closed leaves the circuit unprotected and can result in catastrophic hose or component failure.
