Description:
Rexroth Proportional Valve 4WRBA10EA75-20 G24K4 M-828 is a high-performance electro-hydraulic proportional directional valve produced by Bosch Rexroth. This proportional valve is a direct-acting proportional valve, suitable for ISO 4401 mounting surface, and is able to precisely control the flow and direction of the hydraulic fluid through the proportional solenoid. The maximum working pressure is 315 bar and the maximum flow rate is 42 l/min. 24V DC power supply is supported. This proportional valve adopts advanced proportional solenoid technology, which realizes precise adjustment of the spool position by controlling the size of the input signal, so as to achieve precise control of the flow and pressure of the hydraulic system.
Application areas:
Machining industry: In CNC machine tools and machining centers, this proportional valve can realize high-speed and high-precision machining of workpieces. By accurately controlling the movement speed and direction of the hydraulic cylinder, the machining efficiency and quality can be improved and the machining error can be reduced.
Automotive manufacturing: In the hydraulic control of automotive chassis and suspension systems, the proportional valves can precisely control the movement of hydraulic cylinders to ensure the smooth running and comfort of automobiles. For example, in the hydraulic control system of automobile shock absorbers, the proportional valve can dynamically adjust the flow of hydraulic oil to adapt to different road conditions and driving needs.
Robotics: In industrial robots, proportional valves are used to control the speed and precision of the movement of the robotic arm. Through precise hydraulic control, the robot can realize complex movements and high-precision positioning to meet the needs of automated production.
Plastic Machinery: In injection molding machines and blow molding machines, proportional valves are used to control the opening and closing of the mold, ejection and pressure holding process. By precisely controlling the pressure and flow rate of the hydraulic system, the molding quality can be improved and the scrap rate can be reduced.
Metallurgical and Mining Machinery: In metallurgical and mining equipment, proportional valves are used to control the movement of hydraulic cylinders and hydraulic motors. For example, in the hydraulic system of excavators, proportional valves can realize precise control of buckets and booms, which can improve operational efficiency and safety.
Wood processing machinery: In wood processing equipment, proportional valves are used to control the hydraulic systems for sawing, planing and sanding processes. By accurately controlling the movement speed and pressure of the hydraulic cylinders, the processing accuracy and efficiency can be improved and the waste of wood can be reduced.
Construction machinery: In construction machinery, such as cranes and concrete pump trucks, proportional valves are used to control the movement of the hydraulic system. By precisely controlling the expansion and contraction of the hydraulic cylinder and the speed of the hydraulic motor, the operational efficiency and operating precision of the equipment can be improved.
Advantages:
Precise control: The proportional valve is able to precisely adjust the position of the spool according to the size of the input signal. This precise control capability enables the hydraulic system to realize precise adjustment of flow and pressure to meet the needs of different working conditions.
