150201010091A010 Valve cover assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany 150201010091A010 valve cover assembly is a core sealing and protective component of the hydraulic system of Sany construction machinery. It is specifically designed for the main body of hydraulic valves, relief valves, anti-reverse valves, etc. Its core function is to form a sealed pressure-bearing chamber by tightly fitting with the valve body, supporting the valve stem and transmission mechanism, loading the seals, preventing hydraulic medium leakage, and blocking external dust and impurities from entering the valve. It plays a key role in sealing protection, pressure support, and positioning connection. It is compatible with Sany and various mainstream construction machinery and is widely used in excavators, crawler cranes, loaders, and other models. It is suitable for harsh working conditions such as mining and infrastructure construction and is the preferred component for aftermarket maintenance, parts wholesale, and foreign trade export.
This valve cover assembly relies on professional valve component manufacturing technology and strict quality control. It is made of QT450 ductile iron (casting of the same material as the valve body) and equipped with a flexible graphite gasket. It undergoes precision casting, CNC turning, polishing and sealing strengthening treatment. It has precise dimensions and no burrs, and a surface hardness of HRC50-55. It has excellent corrosion resistance, impact resistance and pressure resistance, and can withstand high-pressure hydraulic conditions. It effectively solves the pain points of valve cover leakage, deformation, cracking and sealing failure, and extends the service life of valve and hydraulic system. It is suitable for long-term use in harsh working conditions.
