150602080013A021 Proportional pressure reducing valve Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a core pressure control component of hydraulic systems, the 150602080013A021 proportional pressure reducing valve boasts four major advantages: precise pressure reduction, fast response, stable operation, and corrosion resistance. It is widely used in excavators, loaders, hydraulic valve groups, and other scenarios, undertaking the functions of proportional pressure regulation and pressure stabilization. Relying on the electronic control pilot signal to drive the main valve core, it uses the piston cross-sectional area difference to reduce pressure. The ratio can be selected as 2:1 or 3:1, which can reduce dynamic and static pressure. The pressure error is ≤8%, stabilizing the system pressure, avoiding equipment damage, and is easy to install and debug.
Compared to ordinary proportional pressure reducing valves, this product uses high-quality materials and is precision-machined, strictly adhering to industrial standards such as GB/T 24919. The main body is made of 20# forged steel (stainless steel can be customized), the valve core is made of hard alloy, and the seals are made of FKM fluororubber. Manufactured through multiple processes, it has a dense, defect-free structure, is resistant to high pressure, wear, and corrosion, effectively solving problems such as inaccurate pressure reduction and seal failure, thus reducing maintenance costs. Its electrically controlled pilot-operated design offers high adjustment accuracy, is suitable for medium and high pressure conditions, and balances precision and stability to meet the pressure control requirements of hydraulic systems.
