Bomag 05887423 Pressure Relief Valve

The Bomag 05887423 Pressure Relief Valve is a genuine OEM component designed for Bomag tandem rollers across a wide range of BW-series models, including the BW 170 AD, BW 174 AD, BW 174 AD-2, BW 184 AD-2, BW 161 AD-4, BW 202 AD-4, BW 203 AD-4, BW 190 AD-4, BW 141 AD-4, BW 154 AD-4, BW 151 AD-4, BW 154 AP-4, BW 174 AP-4, and BW 205 AD 4, among others. Sourced directly from Bomag, this valve is manufactured to the same specification as the original component it replaces, ensuring a direct, correct-fit installation into the hydraulic system. Confirming part number 05887423 against your machine's service documentation before ordering is always recommended given the breadth of variants this valve covers.

Key Features

• Genuine OEM Hydraulic Precision — manufactured by Bomag to exact pressure-setting tolerances, so the valve opens and closes at the correct system threshold — critical for a hydraulic circuit where over- or under-pressure causes immediate performance loss
• Direct OEM Replacement — installs into the existing hydraulic circuit port without adaptation, matching the original valve's thread form, body dimensions, and pressure rating
• Broad Tandem Roller Coverage — fits an extensive range of Bomag BW-series tandem rollers including BW 161 AD-4, BW 174 AD-2, BW 202 AD-4, BW 203 AD-4, BW 190 AD-4, BW 154 AP-4, BW 174 AP-4, and many additional AD, AP, ADH, ADO, APO, and AC variants
• Hydraulic System Protection — a correctly functioning pressure relief valve prevents dangerous pressure spikes from damaging pumps, motors, and hoses; a faulty or worn valve leads to erratic drum drive behavior and potential hydraulic component failure
• Fuel and Hydraulic Safety Compliance — maintaining a calibrated relief valve keeps hydraulic pressure within safe operating limits, protecting both the operator and the machine's hydraulic circuit from overpressure events

A pressure relief valve is a safety and control component in the hydraulic system. It sets the maximum pressure the circuit is allowed to reach — when pressure climbs beyond that threshold, the valve opens to divert fluid back to the reservoir, protecting pumps, motors, cylinders, and hoses from damage caused by overpressure. On a tandem roller, the hydraulic system powers drum drive and vibration, so a relief valve that sticks closed can cause catastrophic component failure, while one that opens too early will rob the machine of drive force and compaction performance. Replacing a worn or out-of-spec valve with a genuine Bomag part number 05887423 restores correct system pressure and keeps the roller operating as intended.
