Product details

TheArm Hold Valvein a PC200-8 excavator is a crucial component that maintains the position of the arm when the control lever is neutralized. Here are some specifics regarding its function and importance:

1. Function:

• The Arm Hold Valve works by utilizing a check valve and spring mechanism.

• When the control lever is in the neutral position, the oil pressure in the bottom of the arm cylinder is maintained through the closure of the check valve.

• This ensures that the arm remains in its current position without drifting or dropping.

2. Importance:

• It provides stability and control during excavation tasks, allowing the operator to precisely position the arm without continuous adjustment.

• Prevents unexpected movement of the arm, which could lead to accidents or damage to the excavator or surrounding area.

3. Potential Issues:

• Wear and tear on the check valve or the valve spring can compromise the ability of the Arm Hold Valve to maintain pressure.

• This may result in the arm dropping or losing position, affecting the precision and safety of the excavation work.

4. Maintenance and Replacement:

• Regular inspection and maintenance of the Arm Hold Valve are essential to ensure its proper function.

• If wear or damage is detected, timely replacement of the valve or its components is recommended to maintain the performance and safety of the PC200-8 excavator.

In summary, the Arm Hold Valve in a PC200-8 excavator plays a vital role in maintaining the position of the arm during excavation tasks. Its proper function is crucial for the precision, stability, and safety of the excavator's operation.
