Product Specification

Description:

The Rexroth Proportional Valve 4WRZE25W8-325-7X/6EG24N9ETK31/F1D3M is a high-performance proportional directional valve manufactured by Bosch Rexroth, a German company. It belongs to the proportional valve series and can proportionally control the pressure, flow, and direction of a hydraulic system based on the input electrical signal. The valve's model code includes its key characteristics: 4WRZE indicates it is a proportional directional valve, 25W8 indicates a bore size of 25 mm and flow rating of 8; 325 indicates a maximum operating pressure of 325 bar, and 7X indicates it belongs to the 7X series, suitable for medium to high-pressure hydraulic systems.
 

Application Areas:

The Rexroth Proportional Valve 4WRZE25W8-325-7X/6EG24N9ETK31/F1D3M is widely used in various industrial fields, particularly where precise control of hydraulic systems is required. Its primary application areas include:
Construction machinery: such as excavators, loaders, etc., where it controls the speed and direction of working equipment.
Industrial Automation: In automated production lines, it is used to control the movement of robotic arms, conveyor belts, and other equipment.
Plastic Machinery: Such as injection molding machines, extruders, etc., used to control mold opening/closing, material flow, and other functions.
Aerospace: Although the dynamic performance of proportional valves is not as good as that of servo valves, they can still be used in some aerospace hydraulic systems where dynamic performance requirements are not stringent.
Shipbuilding: Used in ship steering gear control, hydraulic lifting systems, etc.
Automotive manufacturing: Used in hydraulic equipment on automotive production lines to control the assembly and testing of components.
 

Advantages:

Precise control: The proportional valve can precisely control the pressure and flow of the hydraulic system based on the input electrical signal, achieving continuous, proportional control of the actuator. This makes the equipment's movement smoother and reduces impact and vibration.
High flexibility: The proportional valve offers flexible control methods, allowing hydraulic system parameters to be easily adjusted by changing the input signal. This flexibility enables the equipment to adapt to different working conditions and task requirements.
Fast response speed: Although the response speed of the proportional valve is not as fast as that of a servo valve, it is significantly faster than that of a conventional on/off valve. This enables the equipment to respond more quickly to operational commands, improving work efficiency.
Strong contamination resistance: Compared to servo valves, proportional valves have stronger contamination resistance. They can tolerate impurities in hydraulic oil to a certain extent, reducing failures caused by oil contamination.
Cost-effective: Proportional valves have relatively low costs, especially in large-scale applications, significantly reducing the overall cost of the equipment. This makes them widely used in many industrial fields.
Easy to integrate: This proportional valve uses threaded connections and can be conveniently installed on hydraulic manifold blocks. This design simplifies hydraulic system integration, reduces piping usage, and lowers system complexity and costs.
Multiple control options: In addition to basic electro-hydraulic proportional control, the valve can achieve various control modes through different electrical interfaces and control units. This provides users with more options to meet diverse control requirements.
High reliability: The Rexroth brand is renowned for its high quality and reliability. This proportional valve undergoes rigorous quality control and testing, ensuring stable and reliable operation under harsh working conditions.
Simple maintenance: The proportional valve has a relatively simple structure, making maintenance convenient. Users can easily clean, inspect, and replace components, reducing maintenance time and costs.
Wide range of applications: This proportional valve is suitable for various hydraulic systems, performing well in both high-pressure and medium-pressure systems. This makes it capable of meeting the needs of different users, offering broad applicability.
