JGK005416333 Main valve pipeline Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The JGK005416333 main valve pipeline is a core connection and transmission component of the main valve system in construction machinery. It precisely adapts to the connection between the main valve and hydraulic system of equipment such as Sany excavators and loaders, and is compatible with main valve interfaces and pipelines of similar specifications. As a key carrier for hydraulic transmission in the main valve system, its performance and stability directly affect the overall operating efficiency and service life of the equipment. With its precision molding process, excellent sealing performance, and stringent quality control, it has become the preferred choice for operation and maintenance, effectively solving the pain points of traditional main valve pipelines such as easy leakage, insufficient high-pressure resistance, and poor adaptability, reducing operation and maintenance costs, and ensuring the stable and efficient operation of the main valve system.
This product is manufactured in strict accordance with GB/T10544-2013 and EN 856 standards, and also references relevant application design specifications for hydraulic control valves. It adopts a special high-pressure resistant composite pipeline structure. The main body is made of oil-resistant and wear-resistant synthetic rubber combined with a high-strength steel wire braided reinforcement layer, which can resist the corrosion of various hydraulic media, without swelling or leakage, and is suitable for the high-pressure transmission requirements of the main valve system. The pipeline surface is treated with anti-wear to resist outdoor dust, mechanical friction and ultraviolet corrosion, extend service life, and is suitable for long-term high-frequency operation scenarios. It can stably cope with the complex and harsh working environment of the engineering site.
