150407030025B Check Valve Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

This check valve is a SANY original certified product, deeply rooted in the hydraulic system field, compatible with SANY’s multiple series of hydraulic systems, and meets the needs of similar equipment. It is widely used in complex working conditions such as mining and construction, solving the pain points of traditional check valves such as sealing failure and opening jamming, avoiding oil backflow failure, consolidating the foundation of directional control, and improving the stability and safety of equipment operation.
The product employs precision machining and integrated sealing technology, adhering to industry standards and Sany specifications, with rigorous testing throughout the entire process, ensuring reliable quality. The main body is made of high-quality carbon steel (304 stainless steel optional), quenched, tempered, and treated with anti-corrosion measures, making it corrosion-resistant, wear-resistant, and impact-resistant, resisting hydraulic oil erosion and vibration impact. It features a built-in high-elasticity spring, ensuring precise opening pressure (0.04MPa suitable for pressure pipelines, 0.4MPa back pressure can be customized), sensitive operation, low flow resistance, tight reverse shut-off sealing, and zero leakage under high pressure. Its compact structure is suitable for confined spaces, and the threaded connection allows for convenient installation without complex tools, improving maintenance efficiency and reducing labor costs. It can be combined with relief valves and other devices to expand its functionality.
