Manual Extract: Main Control Valve

Product Overview

The main control valve plays a crucial role in managing the hydraulic system’s operation of the bucket and its attachments. Designed with a tandem circuit for the bucket priority circuit, this control valve ensures efficient performance and optimal control of hydraulic functions.

Oil enters through port F from the pump, with maximum pressure regulated by the relief valve. The bypass circuits allow the oil to travel through the bucket and boom spools, flowing from port E to the drain circuit, before passing through a filter back to the tank. When actuated, the oil directs power to the bucket and boom cylinders. Notably, the bucket priority circuit ensures that the boom remains inactive when the bucket spool is engaged, even if the boom spool is operated.

Key Features

• Tandem Circuit Design: Prioritizes bucket operation for precise control.
• Relief Valve: Sets the maximum pressure to ensure system safety.
• Bypass Circuits: Facilitates smooth oil flow and reduces unnecessary actuation.
• Bucket Priority Circuit: Prevents simultaneous operation of bucket and boom spools.
• Dual Safety Valves: Protects the circuit from abnormal pressures and compensates for oil shortages with suction functionality.

Benefits

• Enhanced Control: Provides reliable and precise management of hydraulic functions.
• Safety Assurance: Features built-in safety valves to handle pressure anomalies.
• Improved Hydraulic Efficiency: Promotes efficient oil circulation and prevents energy waste.
• Priority Operations: Ensures that critical tasks are prioritized for better performance.

Usage Recommendations

• Regularly check and maintain the relief and safety valves to ensure optimal performance.
• Monitor the bypass circuits for any signs of oil leakage or blockages.
• Ensure compatibility with your hydraulic system’s specifications before installation.
• Follow the maintenance standards for longevity and reliable operation.
