60292590 Throttling valve Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 60292590 throttle valve boasts four major advantages: precise adjustment, stable flow, tight sealing, and high pressure resistance. It is widely used in hydraulic circuits of construction machinery such as excavators and loaders, as well as industrial hydraulic systems. It plays a role in stepless flow regulation, pressure buffering, and flow rate control. Relying on the coordinated work of the needle valve core and the adjusting screw, the valve core opening is changed by rotating the adjusting screw, which precisely controls the flow rate of the hydraulic medium. It can achieve smooth adjustment of the action speed of the actuators (cylinders, motors), avoid equipment shock caused by sudden changes in flow rate, and has strong adaptability and convenient installation and debugging. It meets the flow control requirements of high-pressure and high-frequency operations in 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 made of 20# forged steel (stainless steel can be customized), the valve core is a hardened alloy needle structure, and the seals are made of FKM fluororubber. It is made through precision forging, CNC machining, and surface anti-corrosion treatment, resulting in a dense and defect-free structure. The adjustment mechanism is flexible, with low pressure loss, high pressure resistance, wear resistance, and rust resistance. It effectively solves problems such as inaccurate flow regulation, sealing leakage, and valve core jamming, reducing equipment maintenance costs. It is suitable for medium and high pressure working conditions, accurately matching the flow control requirements of hydraulic circuits in various engineering machinery, and balancing adjustment accuracy and service life.
