GVO 708-2L-04312 Pilot Valve Main Pressure Relief Valve Pressure Safety Valve PC60-7 PC70-7 PC120-6 PC100-6 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with PC60-7 PC70-7 PC120-6 PC100-6 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 relief valve is suitable for PC60-7, PC70-7, PC120-6 and PC100-6 excavators. It is an insert-type pressure control valve installed on the main distribution valve, providing pressure limitation and overload protection for the hydraulic system.

The valve body is manufactured by a single-piece process using high-quality alloy steel. The valve core undergoes quenching hardening and high-precision mirror surface grinding, resulting in a high surface hardness that can resist continuous wear caused by the continuous flushing of hydraulic oil, effectively reducing valve core scratches, jams, and action delays. It is also equipped with an oil-resistant and anti-aging O-ring, which maintains stable sealing performance even under long-term high-temperature and high-pressure continuous operation conditions, preventing system leakage, pressure drop, and unstable pressure. The relief valve is responsible for controlling the maximum working pressure of the hydraulic circuit. When the excavation load exceeds the set threshold, it automatically overflows to unload, protecting the hydraulic pump and multi-way valve from damage caused by high-pressure impacts. It can effectively solve common hydraulic faults such as insufficient digging power, inability to maintain pressure, abnormal overflow noise, and stuck compound actions of the excavator.
