What is an LS (Load Sensing) Valve?
The LS (Load Sensing) valve is a critical component in Komatsu's advanced hydraulic system. It works by:
- Sensing Load Demand – The LS valve detects the hydraulic load pressure from the working equipment (boom, arm, bucket, travel motors, etc.)
- Regulating Pump Output – Based on the load signal, the valve adjusts the main hydraulic pump's swash plate angle to deliver the precise flow and pressure required
- Optimizing Efficiency – By matching pump output to actual demand, the LS valve minimizes energy waste and reduces fuel consumption
- Ensuring Smooth Operation – The load sensing function provides smooth, responsive hydraulic control across all machine functions
Without a properly functioning LS valve, the excavator's hydraulic system may experience:
- Reduced digging and lifting power
- Increased fuel consumption
- Erratic or sluggish hydraulic response
- Premature wear on hydraulic components
Applications & Use Cases
The Komatsu 708-2G-03710 LS Valve Assembly is ideal for:
- Fleet Maintenance – Routine replacement of worn or failed LS valves in Komatsu PC-series excavator fleets
- Hydraulic System Overhaul – Complete hydraulic pump and control system restoration projects
- Emergency Repairs – Quick replacement of failed LS valves to minimize operational downtime
- Preventive Maintenance – Proactive replacement as part of scheduled hydraulic system maintenance programs
- Performance Restoration – Restoring lost hydraulic power, responsiveness, and fuel efficiency in aging equipment
