GVO 708-2L-06710 723-40-71900 Pressure Relief Valve Pressure Reducing Valve Pilot Valve PC200-7-8 PC300-7 PC228 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with PC200-7-8 PC300-7 PC228 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 assembly is compatible with the main pressure control valves of PC200-7, PC200-8, PC300-7, and PC228 excavators' hydraulic systems. It is also a core precision component in the distribution valve assembly that manages system pressure and provides overload safety protection. This series of models have a huge market share and are widely used in various engineering sites such as urban infrastructure, earthwork excavation, mining operations, river regulation, demolition and crushing, etc.

The valve block body is made of high-quality and high-strength alloy steel. It undergoes multiple precision processing procedures such as CNC milling, drilling, and internal flow channel honing. The internal oil channels of the valve block are smooth and clean, effectively reducing the resistance of oil flow and minimizing unnecessary power loss. The internal valve core components are made of alloy steel and undergo quenching and tempering treatment for strengthening, significantly enhancing the overall hardness, impact resistance, and fatigue resistance of the valve core. It can withstand the frequent changes in high-pressure oil during excavator operations for a long time. The valve core mating sealing surfaces are processed using high-precision grinding technology, ensuring the valve core's flexible and smooth reciprocating motion. This effectively avoids common faults such as valve sticking, valve core sluggishness, and jamming. The sealing part of the valve port is processed with strict accuracy, able to withstand the continuous erosion of high-pressure oil, and maintains a durable and reliable sealing performance.
