GVO 709-90-73100 Pressure Relief Valve Lift Valve Hydraulic Safety Valve PC100-6S PC100L-6 PC120-6 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with PC100-6S PC100L-6 PC120-6 excavators, is a key pressure control valve in the hydraulic system. It regulates hydraulic pressure, releases overload pressure, protects core hydraulic components such as the main valve and hydraulic pump, and ensures stable operation of the entire machine.

This relief valve is precision-machined from high-quality steel and undergoes overall quenching treatment. Equipped with oil-resistant and high-pressure-resistant seals, it boasts excellent sealing performance, impact resistance, and wear resistance. Suitable for the high-pressure hydraulic conditions of excavators, it effectively prevents internal leakage, pressure loss, operational instability, and vibration.

Product Introduction

This type of relief valve is suitable for PC100-6S, PC100L-6 and PC120-6 excavators. As a pressure safety protection component for the hydraulic system, it regulates the pressure in the circuit in real time to prevent overloading of the hydraulic system. The valve body material is wear-resistant and impact-resistant, and the inner holes are precisely honed. The sealing surface of the valve core has high processing accuracy, reducing internal leakage problems. It is suitable for heavy-duty mining operation environments and can withstand continuous high-pressure impacts during large excavator operations, maintaining the set system pressure stably.
