Rexroth Proportional Valve 4WREE10E25-2X/G24K31/A1V Blue Cast Iron Energy-Saving

Product Specification

Description:

The Rexroth proportional valve 4WREE10E25-2X/G24K31/A1V is a direct-acting proportional directional valve manufactured by Bosch Rexroth. It is operated by a proportional solenoid with centering threads and a removable coil, and integrates electronic components (OBE) with electrical position feedback functionality. The valve's basic components include: a housing with a connection surface, a control valve spool with a compression spring and spring seat, a coil with a centered thread, a position sensor, and integrated electronic components. In the de-energized state, the control valve spool remains at the mechanical center position under the action of the compression spring. When the coil is energized, the control valve spool moves proportionally according to the electrical input signal, thereby achieving precise control of fluid flow. The valve has progressive fluid characteristics, enabling connections from P to A and from B to T, and is suitable for hydraulic systems requiring precise control of flow and direction.

Application Areas:

Construction Machinery: In various construction machinery such as excavators, loaders, and bulldozers, this proportional valve can be used to control the direction and speed of hydraulic cylinders and hydraulic motors, enabling precise control of components like mechanical arms and buckets, thereby enhancing the operational efficiency and accuracy of the equipment.

Industrial Automation Field: In automated production lines, robots, and other equipment, the 4WREE10E25-2X/G24K31/A1V proportional valve can be used to control the movement of hydraulic actuators, enabling precise control of processes such as part handling, assembly, and machining, ensuring production process stability and product quality.

Machine tool field: In CNC machine tools, machining centers, and other machine tool equipment, this valve can be used to control the actions of the hydraulic system, such as spindle speed changes and feed mechanism movements, thereby improving the machining accuracy and efficiency of the machine tool.

Plastic machinery field: In plastic processing equipment such as injection molding machines and extruders, the proportional valve can be used to control the pressure and flow of the hydraulic system, achieving precise control of processes such as injection and extrusion of plastic melt, thereby improving the quality and production efficiency of plastic products.

Advantages

Precise Control: This proportional valve can proportionally regulate the flow and direction of the hydraulic system based on the input electrical signal, enabling precise control of the position and speed of the actuator to meet control requirements under various complex operating conditions.

Integrated Electronic Components: The valve integrates electronic components (OBE) and electrical position feedback functionality, making its control more intelligent and precise. Through the built-in electronic components, real-time monitoring and fault diagnosis of the valve can be achieved, enhancing system reliability and maintainability.

High Response Speed: The proportional solenoid has a fast response speed, enabling rapid response to input signals and achieving quick flow and direction regulation. This high-response characteristic makes the valve suitable for hydraulic systems requiring fast action and frequent switching.

Energy-Saving Effect: By precisely controlling the flow and pressure of the hydraulic system, it avoids excessive energy waste, achieving energy-saving effects. Compared to traditional on/off hydraulic valves, the proportional valve can adjust energy supply according to actual needs, reducing system energy consumption.

Strong contamination resistance: The valve's design and manufacturing process give it excellent contamination resistance. In hydraulic systems, oil contamination is inevitable, but this proportional valve can adapt to a certain degree of oil contamination, reducing failures and maintenance costs caused by contamination.

Easy installation and maintenance: Featuring a plate-mounted connection structure, it is easy to install and integrate into various hydraulic systems. Additionally, its modular design makes maintenance and component replacement simpler and faster.
