60271306 Bucket boom regeneration shut-off valve Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a core control component of the excavator stick regeneration system, the 60271306 stick regeneration shut-off valve boasts four major advantages: accurate switching, fast response, tight sealing, and anti-interference. It is widely used in the hydraulic circuits of various excavator sticks, responsible for switching the regeneration circuit on and off, regulating pressure, and switching operating conditions. Driven by pilot pressure, the valve core moves, and combined with pressure detection sensing the pressure in the rodless chamber of the cylinder, it automatically starts and stops regeneration, effectively solving the problems of cavitation in the rodless chamber and vibration, improving operational coordination, and offering convenient installation and debugging.
Compared to ordinary boom regeneration shut-off valves, this product uses high-quality materials and is precision-machined, strictly adhering to GB/T 24919 and JB/T 10684 standards. The main body is made of 20# forged steel (stainless steel can be customized), the valve core is hardened alloy, and the seals are made of FKM fluororubber. It is manufactured through multiple processes, resulting in a dense and defect-free structure. The piston design is small in size and has low pressure loss. It is resistant to high pressure, wear, and corrosion, solving problems such as valve core jamming and inaccurate switching, reducing maintenance costs, and is suitable for medium and high pressure conditions. It can be used with models such as Yuchai YC60-8 and Doosan DH60-7.
