60348659 High and low speed valve core Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The high-speed and low-speed valve core is a key moving component in the hydraulic motor speed change system. It switches between high and low speeds and regulates the speed by reciprocating and sliding to change the oil circuit. It accurately distributes hydraulic flow and switches working oil circuits, improving problems such as shifting jamming, speed fluctuations, and unstable speed, stabilizing motor speed and torque, and ensuring sensitive equipment switching and smooth operation.
This genuine SANY valve core undergoes quenching hardening, precision grinding, and stress relief treatment, resulting in high precision, fatigue resistance, and resistance to oil erosion. It is suitable for harsh operating conditions such as high-pressure impact, frequent speed changes, and impurity circulation. Old valve cores are prone to scratches, wear, buildup, and deformation, leading to poor shifting, speed imbalance, lack of power at high speeds, and vibration at low speeds. In severe cases, it can cause gear failure and equipment shutdown. This product can be used for in-situ, non-destructive replacement, suitable for maintenance overhauls and bulk stocking, quickly restoring hydraulic transmission accuracy and reducing maintenance costs.
