60205580 One-way Valve Check Valve Control Valve SY215 SY235 SY335 SY485 CLG922 CLG936 Excavator Construction Machinery Parts

Product Description

The GVO excavator relief valve, compatible with SY215 SY235 SY335 SY485 CLG922 CLG936 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 main relief valve, which is compatible with SY215, SY235, SY335, SY485 as well as CLG922 and CLG936 excavators, is a core plug-in pressure control component within the multi-way distribution valve assembly. It plays a crucial role in limiting the pressure of the entire hydraulic system and providing overload relief protection, directly influencing the digging torque of the entire machine, the sensitivity of action response, and the operational safety of the entire hydraulic system. 

The valve body is machined from high-strength alloy steel and undergoes strict quenching and tempering heat treatment. The overall structure has sufficient rigidity and is unlikely to deform under long-term high-pressure operation. The mating surface between the valve core and the valve sleeve is processed using high-precision grinding technology, and the valve port is strengthened through hardening treatment. It can withstand continuous high-speed and high-pressure oil flow, reducing the risk of wear and scratch caused by tiny impurities in the hydraulic oil, and minimizing internal leakage at the valve port. The internal core spring is made of high fatigue-resistant spring steel, which is matched and calibrated for the high-frequency relief operation of domestic large-tonnage excavators. After repeated pressure-bearing, it is unlikely to experience elastic fatigue failure. It is also equipped with high-temperature-resistant and low-temperature-resistant high-quality sealing components, which can adapt to the significant temperature fluctuations of hydraulic oil in construction sites and effectively avoid valve component leakage faults.
