Optional Valves2KAR series (Anti-Reaction Valves)
2KAR series is installed on swing motor to prevent swing back when rotating upper flame of excavator is stopping.
When swing lever is returned to neutral position and rotating upper flame of excavator is stopping, kinetic energy is saved as energy of brake pressure.
When this compressed oil expands, inversion occurs to upper flame of excavator.
- Swing back is reduced at the end of swing.
- Only one rebound at stop.
|Max. Pressure (MPa)||34.3|
