Rexroth Proportional Valve 4WRZ25W8-325-7X/6EG24N9K4/D3M Compatibility 325 L/Min

Product Specification

Description:

The Rexroth Proportional Valve 4WRZ25W8-325-7X/6EG24N9K4/D3M is a high-performance electro-hydraulic proportional directional valve manufactured by Bosch Rexroth, a German company. This valve employs advanced electro-hydraulic proportional control technology to achieve precise control over the flow direction and volume of hydraulic fluid within a hydraulic system. It is a proportional directional valve utilizing pilot-operated control. The nominal bore diameter is 25 millimeters. The spool type is designed for specific flow characteristics. The rated flow rate is 325 L/min. The electrical connection is a 24V DC power supply, with additional features such as an electromagnet, plug, and manual operating device. The valve controls the movement of the pilot spool via an electrical signal, thereby driving the main spool to achieve continuous regulation of hydraulic fluid flow direction and flow rate. This design enables the valve to achieve precise proportional control under various operating conditions.
 

Application areas:

Industrial automation: In the field of industrial automation, this proportional valve is widely used in hydraulic systems requiring high-precision control. For example, in equipment such as injection molding machines, hydraulic presses, and hydraulic shearing machines, the 4WRZ25W8-325-7X/6EG24N9K4/D3M can achieve precise motion control of hydraulic cylinders or hydraulic motors, thereby improving production efficiency and product quality.
Construction Machinery: In construction machinery such as excavators, loaders, and cranes, this proportional valve is used to control the operation of hydraulic cylinders and hydraulic motors. Its high-precision control capability enables smooth transitions during complex movements, improving the operational accuracy and work efficiency of the equipment.
Metallurgy and heavy machinery: In heavy equipment such as steel mills, rolling mills, and presses, this proportional valve can withstand high pressure and large flow rates, enabling precise control of heavy-duty equipment. Its high reliability and durability allow it to operate stably for extended periods under extreme conditions.
Shipbuilding and marine engineering: In ship hydraulic systems, such as steering gear, cranes, anchor winches, etc., this proportional valve provides high-precision control, ensuring stable operation of equipment in harsh marine environments.
 

Advantages:

High-precision control: This proportional valve employs advanced electro-hydraulic proportional control technology, enabling continuous, stepless regulation of hydraulic system flow and direction. Compared to traditional on/off directional control valves, it eliminates hydraulic shock and unstable motion issues, significantly improving system control precision and stability.
Fast response speed: Due to its pilot-controlled structure, the valve has a fast response speed, making it suitable for applications requiring frequent start/stop operations or rapid directional changes. Its dynamic response characteristics meet high-frequency control requirements, enhancing overall system efficiency.
Energy-efficient and high-performance: By precisely controlling fluid flow, the valve minimizes unnecessary energy loss. For example, in low-load conditions, the system automatically reduces flow output to reduce energy waste, enabling energy-efficient operation.
High reliability and durability: Rexroth proportional valves are made of high-quality materials and advanced manufacturing processes, offering excellent wear resistance and contamination resistance. Their rational structural design ensures easy maintenance, a long service life, and suitability for long-term continuous operation.
Compatibility and modularity: This valve can be seamlessly integrated with Rexroth amplifiers, sensors, controllers, and other components to build a complete electro-hydraulic proportional control system. Additionally, its modular design facilitates system expansion and maintenance.
