150602080013A015 Valve stem assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 150602080013A015 valve stem assembly boasts four major advantages: smooth transmission, accurate positioning, strong wear resistance, and excellent sealing. It is widely used in hydraulic valve groups, multi-way valves, and various hydraulic control valves in construction machinery such as excavators and loaders. It undertakes the functions of valve core driving, circuit reversal, and flow regulation. Relying on precision structural design, it achieves precise valve core displacement and transmission without jamming. It can accurately control the on/off state and flow rate of hydraulic medium, avoiding valve group failure caused by valve stem jamming or wear. It has strong adaptability and convenient installation, meeting the high-pressure and high-frequency operation requirements of construction 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 40Cr alloy structural steel (stainless steel can be customized), and the surface is nitrided. It is equipped with FKM fluororubber seals and is made through multiple processes such as precision forging, CNC grinding, and polishing. The structure is dense and defect-free, with high hardness and toughness. It is resistant to high pressure, wear, and corrosion, effectively solving problems such as valve stem wear, deformation, and sealing leakage, reducing maintenance costs. It is suitable for medium and high pressure hydraulic conditions and accurately matches the transmission requirements of hydraulic valve groups in various engineering machinery, balancing transmission accuracy and service life.
