High pressure steering unit – ST HP
ST HP – High Pressure steering unit has been engineered for applications where steering circuit pressure requirement reach up to 275bar.
This project is the ideal solution for construction equipment like backoe loader, large articulated machines, high load forklift and reach stacker. An optimised solution that could meet at the same time customer highest specifications with a competitive price. Available with several customization, with single or dual gerotor, it can be equipped with several built-in valves configurations and also flow amplification.
This steering unit features:
- Highest Pressure Rating
- Compact design for easy integration and interchangeability
- Low noise
- Low torque
- High performance and reliability
Open center Non-reaction (ON)
Load sensing Non-reaction (LS)
