Excavator Parts DF70 Hydraulic Plug-in Valve Pressure Control Valve Relief Valve Construction Machinery

Product Description

The GVO excavator relief valve, compatible with DF70 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

The threaded cartridge relief valve is specially developed for the harsh working conditions of construction machinery. It is suitable for the hydraulic control systems of wheel excavators, small excavators, loaders, and other equipment, and plays a key role in pressure regulation, pressure stabilization, and overload relief. 

The valve body is forged from high-quality alloy steel and undergoes quenching and tempering treatment, enhancing the overall strength and impact resistance. It can withstand frequent pressure fluctuations for a long time. The valve core is precisely ground, with excellent conical surface sealing performance, sensitive pressure response, stable pressure regulation, and no common faults such as pressure drift, jitter, or abnormal noise. The complete set of high-quality sealing components is compatible with various hydraulic oils for construction machinery, resistant to high temperatures and wear, significantly reducing the risk of oil leakage. The standardized threaded cartridge design ensures strong versatility, allowing for easy replacement and disassembly without modifying the pipelines. During maintenance, simply remove the old valve and replace it directly, shortening the downtime of the equipment.
