Description:

Rexroth Proportional Valve 4WRTE25V220L-4X/6EG24K31/A1M is a high performance proportional directional control valve manufactured by Bosch Rexroth. The valve adopts advanced proportional solenoid technology, which can realize precise flow and direction control. The valve uses a proportional solenoid to generate an electromagnetic force proportional to the input signal to control the position of the spool, thus regulating the flow and direction of the hydraulic fluid. Its built-in electronic position feedback system can monitor the spool position in real time to ensure control accuracy. Suitable for medium flow rate hydraulic system. Able to withstand high working pressure, suitable for high-pressure hydraulic systems. Standard hydraulic interface for easy installation and maintenance. Equipped with 24V electrical interface, compatible with various control systems.

Fields of application:

Industrial Hydraulic Systems: Plastic Injection Molding Machines: In the plastic molding process, the opening and closing of the mold and the flow of material need to be precisely controlled. The valve can provide high-precision flow and direction control to ensure the stability of the molding process and product quality.
Die casting machine: in the metal die casting process, need to quickly and accurately control the flow and pressure of hydraulic oil, in order to achieve high quality casting production. The valve's fast dynamic response characteristics enable it to meet this demand.
Stamping presses: In the stamping process, precise control of stamping pressure and speed is required. The valve is able to flexibly adjust the parameters of the hydraulic system according to the requirements of different stamping processes.
Mobile equipment hydraulic system:
Construction machinery: such as excavators, loaders, etc., these devices need to work in complex working conditions, the response speed and control accuracy of the hydraulic system requires high. The valve can quickly respond to the operating instructions to ensure the efficient operation of the equipment.
Agricultural machinery: such as combine harvesters, tractors, etc., need to maintain stable hydraulic control in different terrain and operating conditions. The valve's high adaptability and reliability make it an ideal choice for hydraulic systems in agricultural machinery.
Construction machinery: such as tower cranes, concrete pump trucks, etc., require precise control of pressure and flow in the hydraulic system to ensure the safety and efficiency of the construction process. The valves are able to meet the control needs of these machines under complex working conditions.
Aerospace hydraulic system:
Aircraft Landing Gear: During the retraction and release of aircraft landing gear, the flow and pressure of the hydraulic fluid needs to be precisely controlled to ensure the smooth operation of the landing gear. The valve's high precision and reliability enable it to meet the stringent requirements of the aerospace industry.
Flight control system: In the hydraulic drive section of the flight control system, a fast and precise response to the control signal is required to achieve stable flight of the aircraft. The valve's fast dynamic response enables it to meet this requirement.

Advantages:

High-precision control: The use of advanced proportional solenoid technology enables high-precision flow and directional control. The precise adjustment of the spool position makes the pressure and flow control of the hydraulic system more accurate, and can meet the control requirements under various complex working conditions.
Fast dynamic response: the valve has a fast dynamic response characteristics, can respond to the input signal in a short period of time, to achieve fast and stable control. This allows the hydraulic system to operate more efficiently and reduces energy waste.
Low leakage rate: The use of high-quality sealing materials and precision machining technology ensures an extremely low leakage rate. Low leakage not only helps to improve the efficiency of the hydraulic system, but also extends the life of the system and reduces maintenance costs.
Wide working range: the valve has a wide working range and can adapt to different hydraulic systems and working conditions. Whether it is low pressure high flow or high pressure low flow, it can provide stable and reliable control performance.
Easy maintenance and operation: With modular design, the structure is simple and compact, which is easy to install and maintain. At the same time, the valve is equipped with advanced electronic diagnostic system, which can monitor the working status in real time and provide timely alarm prompts, so that operators can find and solve problems in time.
High reliability: Due to its high-quality manufacturing process and advanced control technology, the valve can maintain stable performance under various severe working conditions, reducing the probability of failure and improving the overall reliability of the system.
