Komatsu Loader Valve 423-43-47303 423-43-47302

 

 

1. Hydraulic system pressure control
This valve belongs to the category of relief valves or safety valve accessories, and its main function is to limit the maximum working pressure of the hydraulic system, prevent oil pipe rupture, valve core damage, or main pump failure caused by overload or external impact (such as heavy objects falling).
2. Protect critical components
In loader operations, this valve releases excess pressure to protect hydraulic actuators such as cylinders, buckets, and arms from high-pressure impacts, extending equipment life.
3. Specific model adaptability
Specially designed for models such as WA380-6 and WA430-6, it may involve pressure regulation of steering systems, hydraulic circuits of working devices, or braking systems.

4.Installation and commissioning
-Before installation, ensure that the valve body is clean to prevent impurities from entering the hydraulic system.
-During debugging, the opening pressure should be calibrated using pressure testing equipment to ensure compliance with the set values required by the model (refer to the technical manual).
