A valves in hydraulic system consists of hydraulic pumps, hydraulic motors, hydraulic oil tank, hydraulic valve spool, hydraulic valves, and other components, serving as a hydraulic power source device or a hydraulic device including hydraulic valve control. It supplies oil according to the flow direction, pressure, and flow rate required by the driving device, suitable for various machines where the driving device is separated from the hydraulic station. By connecting the hydraulic station with the driving device (cylinder or motor) using hydraulic pipes, the valves in hydraulic system can perform various specified actions.
Next, we will introduce you to the application of Rekith hydraulic valves in hydraulic systems.
The characteristics and advantages of Rekith hydraulic valves
Rekith hydraulic valves possesses strong independent research and manufacturing capabilities, mastering key technologies in hydraulic valve production. It has production processes for switch solenoids, proportional solenoids, and coils synchronized with German technology, as well as comprehensive system design capabilities for electro-hydraulic control.
Basic processing technology of the valve core: Turning – Heat treatment – Grinding Domestic materials have uneven quality and poor consistency, making it difficult to control the depth of carburization and deformation after heat treatment. Therefore, the valve core materials for most competing hydraulic products are imported, which is one of the reasons for high costs. Another factor affecting the quality of the valve core is production process control. The valve cores are placed separately in each process to avoid collisions that may affect performance. In addition, our grinding process control includes: Rough grinding – Deburring – Semi-finish grinding – Deburring – Finish grinding – Deburring – Ultrasonic cleaning. The grinding fluid is equipped with a special recycling and filtering device, and the entire process is strictly controlled. There is also a difference in the valve core structure: there is an important structure on the valve core called a pressure equalization groove (balance groove). The roundness of the pressure equalization groove depends entirely on the lathe’s rotary accuracy. Our valve cores are produced using lathe milling compound machine tools costing hundreds of thousands. The hydraulic valve body adopts shell casting technology, and after the two sides of the hydraulic valve body are cast, no further processing is carried out. Generally, the shell strength of castings is the highest, supplemented by the design of concave grooves at the installation bolt positions, which can effectively improve the rigidity of the valve body. In addition, the material of the valve body blank (cast iron grade HT250) with a hardness range between HB185-225 is qualified, but we require a hardness not lower than HB200, and the difference in hardness on the same surface cannot exceed 10 degrees, ensuring the wear resistance of the product and the consistency of material hardness. Higher working and pilot pressures Larger flow rate Higher power limit Lower pressure loss Lighter, more compact Rich configuration High repeatability of solenoid valves, fast response speed, good durability Our hydraulic valves are products that have been verified and optimized for different working conditions, making these hydraulic control valves more suitable for specific equipment. We also provide customized and personalized services for our products. Our delivery time leads the industry. The future direction of our hydraulic valve components is towards more intelligence and compactness.
Valves in hydraulic system Practical Application Case
Before using Rekith brand valves, a manufacturing company’s hydraulic system utilized low-pressure valves from a Taiwanese brand, resulting in lower pressure and flow rates. After implementing Rekith’s high-pressure, high-flow hydraulic valve replacement solution, the hydraulic system experienced a significant decrease in oil temperature and an increase in working speed. The improvement effect was evident and significantly superior to the Taiwanese valves. Currently, the customer is highly satisfied and has commenced mass production
