60357916 Logic cone valve body Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As the core pressure-bearing and sealing component of a logic valve, the 60357916 logic cone valve body boasts four major advantages: accurate sealing, high pressure resistance, wear resistance, and stable structure. It is widely used in the hydraulic systems of engineering machinery such as excavators and cranes, as well as logic valve assemblies of heavy equipment in metallurgy and mining. It undertakes the functions of guiding the valve core, sealing the medium, and bearing pressure. Relying on the precision cone surface design and precise fit with the valve core, it achieves reliable sealing of the hydraulic medium and logic on/off control. It can work in conjunction with pilot elements to flexibly realize composite logic functions such as overflow, sequence, and reversal. It is suitable for high-pressure and high-flow conditions, effectively avoiding valve assembly failure caused by medium leakage and cone surface wear. It is easy to install and meets the operating requirements of complex hydraulic circuits in engineering machinery.
This product is made of high-quality materials and precision-machined, strictly following GB/T 24919 and JB/T 10684 standards. The main body is made of high-quality cast iron (20# forged steel and 304/316L stainless steel can be customized). The conical surface is precision ground and fitted with an FKM fluororubber sealing adapter structure. It is manufactured through multiple processes such as precision casting, CNC turning, and fine grinding and polishing. The structure is dense and free of defects such as sand holes and air holes. The conical surface has high fitting accuracy, high pressure resistance, wear resistance, and rust resistance. It effectively solves problems such as conical surface wear, sealing leakage, and structural deformation, reducing equipment maintenance costs. It is suitable for medium and high pressure and high flow conditions, accurately matches the assembly requirements of various logic valve groups, takes into account sealing accuracy and structural stability, and can be seamlessly adapted to various logic valve cores, simplifying the valve group assembly process.
