Product Detail

Pressure Regulation: The main function of the PC220-7 Main Relief Valve is to regulate the hydraulic pressure in the system.

It ensures that the pressure does not exceed the predetermined limit, preventing damage to the hydraulic components and ensuring safe operation. Precise Adjustment: The valve is equipped with an adjustable pressure setting, allowing operators to fine-tune the system pressure according to the specific requirements of the task at hand. This feature enhances versatility and performance in various working conditions. Safety Features: The PC220-7 Main Relief Valve is designed with safety in mind. It incorporates pressure relief and overload protection mechanisms to prevent system failures and potential accidents. These safety features contribute to the longevity of the hydraulic system and the overall durability of the excavator. Working Principle: The PC220-7 Main Relief Valve operates based on the principle of pressure regulation. It is installed in the main hydraulic circuit and constantly monitors the pressure within the system. When the pressure reaches or exceeds the predetermined limit, the valve opens to allow excess hydraulic fluid to bypass the system and return to the hydraulic tank. The valve consists of a spring-loaded plunger that is pushed against the hydraulic fluid by an adjustable spring. As the pressure in the system increases, it acts against the force of the spring, compressing it. Once the pressure exceeds the set limit, the spring is compressed sufficiently to open the valve and divert the excess flow. Specifications:

Pressure Rating: The PC220-7 Main Relief Valve is designed to handle hydraulic pressures up to a specific limit.

The exact pressure rating may vary depending on the specific model and configuration. However, as a general specification, it can handle pressures in the range of 2500 to 3000 pounds per square inch (psi). Flow Capacity: The valve is designed to accommodate a certain flow rate of hydraulic fluid. The flow capacity is typically specified in gallons per minute (GPM) and can range from 50 to 100 GPM, depending on the model and application. Adjustability Range: The PC220-7 Main Relief Valve provides an adjustable pressure setting to allow fine-tuning according to the requirements of the task. The adjustable range typically varies between 1000 and 2500 psi, allowing operators to optimize the system pressure for different operating conditions. Compatibility: The PC220-7 Main Relief Valve is specifically designed for use in the Komatsu PC220-7 excavator. It is engineered to fit seamlessly into the hydraulic system of the machine and provide reliable pressure regulation.
