B230103003140 Main Valve Pipeline Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The B230103003140 main valve pipeline is a core connecting 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. 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 compatibility, reducing operation and maintenance costs, and ensuring the stable operation of the main valve system.
This product is manufactured in strict accordance with GB/T10544-2013 and EN 856 standards. 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 reinforcing 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.
This product is manufactured using CNC precision molding technology, with dimensional errors controlled within ±2%. It accurately matches the main valve interface specifications, making installation convenient and allowing for direct replacement. It features a built-in dedicated sealing structure, providing excellent sealing performance and preventing leakage under high temperature and high pressure conditions. It also possesses good flexibility and shock resistance, making it suitable for complex equipment installation spaces, reducing vibration damage to pipelines, and lowering the downtime failure rate.
