SSY007667619 Main Valve Frame Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a core load-bearing component of the main valve system, the SSY007667619 main valve frame boasts four major advantages: high rigidity, accurate positioning, impact resistance, and easy assembly. It is widely used in heavy-duty construction machinery such as cranes and excavators, undertaking the functions of fixing, supporting, and protecting the main valve and valve assembly. It provides a precise installation benchmark, ensuring flexible operation and reliable sealing of the main valve, guaranteeing the normal operation of the hydraulic control system, and is compatible with various machine models, offering convenient installation.
Compared to ordinary main valve frames, this product uses high-quality materials and is precision-machined, strictly adhering to industrial standards. The main body is a WCB carbon steel casting (compliant with ASTM A216 standards, suitable for medium and high pressure conditions), manufactured through multiple processes, resulting in a robust and defect-free structure with excellent impact resistance, wear resistance, and corrosion resistance. This effectively solves problems such as deformation and cracking, reducing maintenance costs. Its integrated structure features pre-drilled holes and stops to meet assembly requirements, adapting to complex operating conditions and balancing reliability and convenience.
