Product Description
Core Parameters：
- Part Number: 723-40-75200 (Alternative: 723407520)
- Type: Hydraulic pressure relief valve assembly
- Material: High-strength forged steel valve body + precision spool + high-pressure resistant seal rings
- Structure: Integrated valve block design, including adjusting bolt, spool and seal components, for direct installation on the main control valve
- Function: Limits maximum hydraulic system pressure to prevent overload damage to pumps, valves and pipelines, and stabilizes system working pressure
Function & Application：
- Overload Protection: When hydraulic system pressure exceeds the set threshold, the spool opens to relieve excess oil back to the tank, preventing burst or damage to core components like pumps, valves and cylinders.
- System Pressure Stabilization: Precisely sets the safe pressure via the adjusting bolt, maintaining the hydraulic system within a safe pressure range for smooth and controllable operation.
- Contamination Resistance & Durability: Precision-machined spool and wear-resistant seal rings resist hydraulic oil contamination, adapting to high-load and long-hour operation to extend service life.
- OEM Compatibility: Manufactured to Komatsu original equipment standards, with perfectly matched mounting holes, oil passages and dimensions, enabling direct replacement of the original 723-40-75200 assembly without modification.
Application Scenario：
Suitable for maintenance and replacement of the hydraulic main control valve in Komatsu PC210-10MO/PC215-10MO/PC228US-11 excavators. It is a key hydraulic protection component to ensure the safe and stable operation of the hydraulic system.
