152300000146A002 Relief valve Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 152300000146A002 relief valve is a core pressure control component in the hydraulic system of Sany construction machinery. Specifically designed for Sany excavators and loaders, it is compatible with SY65, 75-8/9, and SY365 series models and similar hydraulic systems, earning it the reputation of a “safety valve” for hydraulic systems. Its core function is to monitor system pressure in real time, automatically opening the relief channel to relieve pressure and prevent overload when the pressure exceeds a set threshold, while maintaining a constant outlet pressure of the fixed displacement pump. Through precision manufacturing and stringent quality control, it effectively solves the pain points of traditional relief valves, such as inaccurate pressure adjustment and slow opening/closing, reducing failure and maintenance costs, making it a preferred maintenance accessory.
This product adopts a dedicated SANY adapter design with a size error within ±0.2mm. The mounting hole positions conform to national standards, allowing for quick assembly and replacement without special tools. The structure has been mechanically optimized, the valve core is wear-resistant and can withstand a nominal pressure of 31.5MPa, and has excellent vibration and shock resistance. It can prevent valve core jamming and valve body cracking, reduce unplanned downtime losses, and is suitable for harsh working conditions.

Core technical parameters:
