Product Specification

GVO Excavator Parts PC200-5 Construction Machinery Hydraulic Parts Pressure Safety Valve Rotating Motor Relief Valve

Product Description

The GVO excavator relief valve, compatible with PC200-5 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 specially developed for the main control valve of the PC200-5 excavator. As the main pressure control valve of the entire hydraulic system, also known as the main gun in the industry, it plays a core role in limiting the maximum pressure of the entire hydraulic system and providing overload protection. It directly determines the pressure level of the entire system and controls the output power of all actions such as digging, rotating, and moving. Once the performance of the overflow valve deteriorates, it will directly cause a series of typical faults such as insufficient power of the entire machine, inability to dig, and a decrease in cooling system pressure. It is an indispensable key precision component in the PC200-5 hydraulic system.

The valve body is made by forging a high-strength alloy steel as a whole, and is subjected to a quenching and tempering heat treatment process. The internal flow channels of the valve body are precisely machined, and the valve core is processed by high-precision grinding. It is combined with high-toughness anti-pressure springs and high-pressure fluororubber sealing elements, which can withstand the high-frequency and high-pressure impact during the excavator's operation for a long time. In heavy-load working conditions such as earth excavation and stone crushing, the valve core responds quickly and sensitively when opening and closing, and the relief action is crisp and decisive, effectively avoiding the continuous leakage problems caused by valve core jamming, spring deformation, and seal damage, significantly reducing the probability of equipment experiencing problems such as inability to adjust the pressure or large pressure fluctuations.
