150602080013A004 Multi-way valve cover assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a core protective sealing component of multi-way valves, the 150602080013A004 multi-way valve cover assembly boasts four major advantages: tight sealing, stable structure, high pressure resistance, and easy assembly. It is widely used in multi-way valve assemblies of construction machinery such as excavators and loaders, as well as heavy equipment in metallurgy and mining. It undertakes the functions of valve core guidance, oil circuit sealing, pressure bearing, and protection. Relying on a precision integrated design, it fits precisely with the valve body, isolating impurities and preventing media leakage. This ensures accurate switching and stable flow of the multi-way valve. It seamlessly adapts to the valve core and valve plate, avoiding jamming and malfunction caused by valve cover deformation and sealing failure. Installation is convenient, suitable for high-frequency operation, and easy to inspect and maintain.
Compared to ordinary valve cover assemblies, this product uses high-quality materials and is precision-machined, strictly adhering to industry standards. The main body is made of high-quality cast iron (stainless steel can be customized), the sealing surface is precision ground, and it is equipped with FKM fluororubber seals. It is manufactured through multiple processes, resulting in a dense and defect-free structure, high sealing precision, high pressure resistance, wear resistance, and rust resistance. It solves problems such as sealing leakage and deformation, reduces maintenance costs, is suitable for medium and high pressure and high flow conditions, accurately matches the assembly requirements of multi-way valves in engineering machinery, simplifies the assembly process, and improves efficiency.
