The Distribution Valve for SK250-8 and SK260-8 Excavators
Overview
The distribution valve is a crucial component in the hydraulic system of excavators, responsible for distributing the hydraulic oil outputted by the hydraulic pump to the hydraulic cylinders of various actuators (such as the boom, arm, and bucket) to drive the various movements of the excavator. For the SK250-8 and SK260-8 excavator models, the design and structure of their distribution valves are typically matched to the overall performance and functional requirements of the excavators.
Functional Characteristics
1. Precise Control: The distribution valve can precisely control the flow rate and pressure of the hydraulic oil, thereby achieving precise control over the movements of the excavator. This helps improve work efficiency and operational accuracy.
2. Multi-output Ports: The distribution valve has multiple output ports that can simultaneously provide hydraulic oil to multiple actuators. This ensures that the excavator can perform multiple actions simultaneously, enhancing work efficiency.
3. High Pressure Resistance: The distribution valve can withstand the impact of high-pressure hydraulic oil, ensuring it can operate normally under harsh conditions.
4. High Reliability: The distribution valve is made of high-quality materials and advanced manufacturing processes, resulting in high reliability and durability. This helps reduce failure rates and maintenance costs.
Structural Composition
The distribution valve typically consists of components such as the valve body, valve spool, spring, and seals. The valve body and valve spool are the main parts of the distribution valve, which ensure the correct distribution of hydraulic oil through precise fitting and sealing. The spring provides the necessary preload to ensure the stability of the valve spool in the closed state. The seals prevent hydraulic oil leakage, ensuring the normal operation of the system
