The PC (Pressure Compensated) valve in the PC200 - 7 excavator is a crucial hydraulic component. Its main function is to control and regulate the flow of hydraulic fluid to different actuators in a pressure - compensated manner. This ensures that the flow rate remains relatively stable regardless of the changes in the load pressure, providing more precise control of the excavator's working parts such as the boom, arm, and bucket.

Pressure Compensation Range
The PC valve in the PC200 - 7 is designed to operate effectively within a pressure compensation range. Typically, this range might be from around 100 bar to 300 bar. The valve is able to sense the pressure changes within this range and adjust the flow of hydraulic fluid accordingly. For example, when the load on the actuator increases and the pressure rises, the PC valve compensates to maintain a consistent flow rate to that actuator.
Maximum Operating Pressure
The maximum operating pressure of the PC valve is usually set to around 320 bar. This value is determined based on the overall hydraulic system design and the strength of the components to ensure safety and reliability. It provides a safety margin to prevent damage to the valve and other associated hydraulic components during peak load conditions or sudden pressure spikes.
