60348651 Valve seat Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The valve seat is a key sealing component of the hydraulic valve assembly, providing precise sealing support for the valve core. It works in conjunction with the valve core to open and close the oil circuit and lock the pressure. Thanks to its high-precision fit, it eliminates problems such as oil leakage, cross-contamination, and spillage, stabilizing system pressure, ensuring reliable equipment locking, smooth operation, and improving the stability of the hydraulic system.
This SANY original valve seat undergoes quenching hardening, precision grinding, and stress relief treatment, resulting in a smooth sealing surface, precise tolerances, and resistance to deformation under pressure. It is suitable for harsh operating conditions such as high-pressure impact, high-frequency opening and closing, and heavy-duty scouring. Old valve seats are prone to scratches, wear, deformation, and scale buildup on the sealing surface, leading to hydraulic pressure loss, insufficient pressure, slippage, and power reduction. In severe cases, it can cause abnormal valve noise and equipment shutdown. This product can be replaced in situ without damage, suitable for maintenance overhauls and bulk stocking, quickly restoring hydraulic sealing and pressure control accuracy, and reducing maintenance costs.
