60357906 Logic control valve Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 60357906 logic control valve boasts four major advantages: precise logic, fast response, tight sealing, and modularity. It is widely used in the hydraulic systems of heavy equipment such as cranes, excavators, aluminum extrusion presses, and rolling mills. It performs functions such as oil circuit on/off switching, reversing, pressure regulation, and logical linkage control. Relying on the pilot valve signal to control the main valve core’s movement, it can be combined to achieve basic logic functions such as AND and OR gates. It is adaptable to multi-action coordinated control in complex hydraulic circuits, avoiding equipment malfunctions caused by logic disorder, ensuring efficient and stable system operation, and is compatible with various machine models. It is easy to install and can be flexibly configured.
This product is made of high-quality materials and precision-machined. The main body is made of 45# forged steel (304/316L stainless steel can be customized). The valve core adopts a conical sealing structure, and the sealing element is made of oil-resistant fluororubber (FKM). It is made through precision forging, CNC machining, and surface anti-corrosion treatment, resulting in a compact and dense structure free from defects such as sand holes and air bubbles. It has excellent high pressure resistance, wear resistance, and corrosion resistance, effectively solving problems such as logic disorder, slow response, and sealing failure, and reducing equipment maintenance costs. Its cartridge-type modular design allows for valve plate combination according to circuit requirements, saving installation space. It is compatible with PN31.5-PN42 pressure ratings, balancing control accuracy and assembly flexibility, and precisely matching the logic control requirements of medium and high pressure hydraulic systems.
