Product Description

The GVO excavator relief valve, compatible with PC800SE-8 PC850SE-8 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 overflow valve is suitable for PC800SE-8 and PC850SE-8 large-sized excavators. It serves as a safety pressure-limiting protection component for the hydraulic system, monitoring the pressure in the circuit in real time and preventing the hydraulic system from overloading and damage.

The valve body is made of wear-resistant alloy steel. The inner holes are precisely honed, and the sealing surfaces of the valve core and valve seat have high processing accuracy, significantly reducing the internal leakage. The product is suitable for heavy-duty mining operation scenarios and can withstand the continuous high-pressure impact of excavation operations, maintaining the set system pressure stably. It is processed strictly according to the original factory dimensions, with good interchangeability. The disassembly, replacement and assembly are simple and convenient, making it a core component for hydraulic maintenance of this series of large excavators.
