Excavator Parts Pilot Valve 60 70 80 90 100 110 120 Pressure Control Valve Relief Valve Construction Machinery

Product Description

The GVO excavator relief valve, compatible with 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 can be used for pressure regulation in the pilot circuit, or as a safety relief valve for the branch circuit to solve problems such as insufficient equipment pressure, excessive pressure causing equipment to stall, and abnormal noise and shock in the oil circuit. It has undergone full pressure testing during factory production, and each valve has completed pressure calibration to ensure that the opening pressure and return seat performance meet the standards. The performance is benchmarked against the original quality, and it is a cost-effective alternative.

In the long-term high-load operation environment of construction machinery, the hydraulic system is prone to instantaneous high-pressure impacts, which can easily cause pump and valve damage, oil pipe rupture, and other problems. This plug-in relief valve can effectively mitigate these risks. The external body of the valve is precisely machined, with high thread accuracy, tight installation fit, and the O-ring sealing point design is reasonable, eliminating external leakage at the installation position. The internal springs have undergone fatigue tests, and repeated opening and closing will not cause spring fatigue failure. The pressure regulating nut can achieve pressure adjustment as needed, meeting the requirements of different equipment oil circuit settings. Whether it is new machine matching or old machine repair replacement, it can function stably and effectively improve phenomena such as equipment pressure憋, weak movement, and system overheating.
