check valve control valve for excavator hydraulic circuits. Size: 4.5 pressure. Designed to restore and maintain proper flow control in compatible excavator systems. Key benefits Controls hydraulic flow to prevent unintended backflow and pressure surges that can affect performance. Matches specified 4.5 pressure size for correct fit and operation in systems using this pressure rating. Compatible with LG485 model applications and systems identified as 2.5 pressure or 4.5 pressure, allowing straightforward replacement of worn or damaged check valves. Helps protect downstream hydraulic components by maintaining correct pressure and flow direction. Important attributes Function: check valve control valve for excavator hydraulic lines. Compatibility: Specified for LG485 model compatibility and for systems calling out 2.5 pressure or 4.5 pressure configurations. Size: 4.5 pressure as indicated. Performance: Intended to restore proper flow control and pressure behavior in matched hydraulic circuits. Application: Replacement part for excavator hydraulic valve assemblies and circuits. Use scenarios Field replacement during routine hydraulic system maintenance to a failed check valve and restore proper flow control. of a valve block on an LG485 compatible excavator where flow issues or pressure imbalances have been diagnosed. Component swap during refurbishment of hydraulic control systems specified for 2.5 pressure or 4.5 pressure operation to ensure correct line behavior. Notes Confirm pressure specification and model compatibility before installation to ensure correct fit and operation. Installation by a qualified technician is recommended to verify system settings and safe operation.
