Manual Extract Regulating Valve (DA Valve)
Product Overview
The DA valve plays a crucial role in regulating the control pressure (Pst) that initiates the travel of the machine by gauging the engine speed. This mechanism ensures the effective management of the hydraulic system, ensuring smooth and responsive machine operation.
Key Features
- Pressure Control: Efficiently regulates control pressure (Pst) in response to engine speed.
- Hydraulic Integration: Works in conjunction with the HST charge pump to maintain hydraulic stability.
- Piston Mechanism: Utilizes piston (6) to manage flow and pressure, enhancing operational precision.
Benefits
- Improved Travel Control: Increases travel speed proportionally with engine speed, providing smooth transitions.
- Consistency: Ensures consistent machine performance by maintaining optimal pressure settings.
- Enhanced Efficiency: By adapting to engine speed, it maximizes hydraulic efficiency and resource usage.
Usage Recommendations
- Regularly monitor and adjust the DA valve settings to maintain optimal machine performance.
- Ensure the HST charge pump is operating within specified parameters for effective valve operation.
- Consult the machine’s maintenance manual for specific instructions on adjusting and servicing the DA valve.
