Material Composition
Constructed from high-grade alloy steel that has undergone precision forging and specialized surface treatments to withstand harsh industrial conditions and fluid contamination.
Structural Characteristics
Features a compact and robust valve body design, optimized for high-pressure sealing and efficient fluid routing. The internal spool is precision-ground to ensure minimal internal leakage and smooth shifting.
Working Principle
The valve operates by using an electromagnetic coil to shift an internal spool. This movement opens and closes specific internal fluid passages, thereby directing the pressurized hydraulic oil to different ports to control the extension or retraction of hydraulic cylinders or the rotation of hydraulic motors.
Installation Requirements
Must be mounted on a clean, flat surface with proper alignment to the hydraulic manifold. Ensure all hydraulic lines are free of debris before connection to prevent internal damage. Electrical connections must match the specified voltage and polarity.
Usage Precautions
- Always install a high-quality hydraulic filter upstream to protect the precision spool from particulate contamination.
- Ensure the hydraulic fluid viscosity is within the recommended range for the operating temperature.
- Do not exceed the maximum rated pressure of 350 bar to prevent internal component failure.
