GVO 723-46-17610 Hydraulic Valve Pressure Relief Valve Logic Valve Bypass Valve PC200-7 PC200-8 PC300-8 PC450-7 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with PC200-7 PC200-8 PC300-8 PC450-7 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 a crucial main pressure control valve on the distribution valve assembly of PC200-7, PC200-8, PC300-8, and PC450-7 excavators. It is also commonly referred to as the main gun within the industry and directly controls the maximum working pressure of the entire hydraulic system, undertaking the core task of overloading protection for the hydraulic system.

The valve body is made of high-toughness and high-strength alloy steel as the raw material. The entire body undergoes quenching and tempering heat treatment process, significantly enhancing the structural strength, impact resistance, and fatigue resistance of the valve body. The valve core is processed by high-precision mirror grinding, and the valve port sealing position is precisely matched and ground to ensure smooth and unobstructed reciprocating motion of the valve core, reducing the occurrence of jamming and sticking faults. The valve port sealing surface is resistant to high-frequency and high-pressure oil liquid erosion, with excellent wear resistance. The entire set of valve components is equipped with multiple groups of high-quality sealing components. The sealing ring is made of rubber material that is resistant to high pressure, hydraulic oil corrosion, and aging, greatly reducing the probability of internal leakage and external oil seepage in the valve body, and perfectly adapting to complex and harsh actual working conditions such as large dust, large temperature fluctuations, and high amounts of hydraulic oil impurities.
