Золотник пропорционального селекторного клапана коробки передач Caterpillar 8S3406

The Transmission Selector Valve Ratio Spool is responsible for regulating the flow of hydraulic fluid to control gear selection. When the operator shifts gears, the ratio spool adjusts its position within the valve body, directing hydraulic pressure to engage the desired gear ratio. This action facilitates smooth and accurate gear changes, optimizing equipment performance and efficiency.Attributes:• Resistant to wear.• Smooth surface finish to reduce friction and wear.• High-pressure resistance to withstand hydraulic pressures.• Enhanced sealing properties to prevent leaks and contamination.• Withstands mechanical stresses and vibrations.Applications: The Transmission Selector Valve Ratio Spool is positioned within the transmission selector valve, this spool regulates hydraulic fluid flow to engage the desired gear ratio.
