The Bomag 05850686 Load Safety Valve is a genuine OEM component designed for Bomag BM 500/15, BM 600/15, BM 500 15 P8, and BM 600/15 EU-Flex T4i cold milling machines. Sourced directly from Bomag, this valve matches the original specification for a direct, no-hassle installation. If your cold milling machine is showing signs of hydraulic pressure irregularities or a worn valve is compromising circuit protection, replacing it with part number 05850686 restores proper system operation.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's exact pressure-relief specification, ensuring the valve opens and seats at the correct threshold for your machine's hydraulic circuit
- Direct OEM Replacement — engineered to install in the same position as the original, using the same port connections and thread dimensions found on the BM 500/15 and BM 600/15 platforms
- Broad Cold Milling Coverage — fits the BM 500/15, BM 600/15, BM 500 15 P8, and BM 600/15 EU-Flex T4i cold milling machines, covering multiple variants in the BM compact milling line
- Hydraulic Circuit Protection — a correctly functioning load safety valve prevents overpressure events that can damage pumps, motors, and downstream hydraulic components, keeping milling performance consistent
- Overpressure Safety — in a hydraulic load circuit, a faulty or stuck valve can expose critical components to damaging pressure spikes; replacing it with a genuine part maintains the protective relief threshold the system depends on
A load safety valve is a pressure-relief device within the hydraulic load-sensing circuit of a cold milling machine. Its job is to cap hydraulic pressure at a set limit, diverting flow when demand exceeds safe operating levels and protecting pumps, motors, and actuators from overpressure damage. On compact cold milling machines like the BM 500/15 and BM 600/15, where the cutter drum, conveyor, and propulsion systems share a common hydraulic network, a failed or drifted load safety valve can cause erratic cutting performance, overheating, or component failure — making timely replacement essential to keeping the machine operating at full capacity.
