60357898 Logic control valve Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 60357898 logic control valve boasts four major advantages: accurate control, fast response, tight sealing, and anti-interference. It is widely used in the hydraulic systems of construction machinery such as excavators and cranes, as well as the hydraulic circuits of heavy equipment in metallurgy and mining. It undertakes the functions of circuit logic on/off, pressure regulation, direction switching, and compound control. Relying on the core cone valve and the pilot element working together, it controls the opening and closing of the valve core by controlling the change of oil port pressure. It can be flexibly combined to realize logic functions such as “AND gate”, “OR gate”, and “NOT gate”, adapting to multi-circuit collaborative control under complex working conditions, effectively avoiding circuit malfunctions, improving system operation stability, and is easy to install, meeting the high-pressure and high-flow 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 cast iron (20# forged steel and stainless steel can be customized), the valve core is a hardened alloy cone valve, and the seals are made of FKM fluororubber (compatible with NBR seals). It is made through precision forging, CNC machining, and surface anti-corrosion treatment, resulting in a dense and defect-free structure. The modular design is compact, with low pressure loss, high pressure resistance, wear resistance, and rust resistance. It effectively solves problems such as valve core jamming, inaccurate control, and sealing leakage, reducing equipment maintenance costs. It is suitable for medium and high pressure and high flow conditions, accurately matching the hydraulic circuit logic control requirements of various engineering machinery, balancing control accuracy and service life. It can seamlessly connect with various control systems, offering high flexibility.
