Rexroth Proportional Valve 4WRZE10W8-85-7X/6EG24N9EK31/A1D3M Compatibility

Product Specification

Description:

The Rexroth Proportional Valve 4WRZE10W8-85-7X/6EG24N9EK31/A1D3M is a high-performance pilot-operated proportional directional valve manufactured by Bosch Rexroth. This valve is designed for precise control of hydraulic oil flow direction and volume, and is widely used in industrial automation, construction machinery, and hydraulic systems. This valve is a pilot-operated proportional directional valve. The nominal bore is 10 mm. The valve spool type is suitable for specific flow characteristics. The rated flow rate is 85 L/min. Additional functional information includes electrical connection methods, solenoid type, and plug configuration. The valve controls the movement of the pilot spool via a proportional solenoid, thereby driving the main spool to achieve continuous regulation of hydraulic fluid flow direction and flow rate. Its proportional control characteristics allow precise regulation of the movement direction and speed of hydraulic actuators (such as hydraulic cylinders or motors) based on the magnitude of the input electrical signal.
 

Application Areas:

Industrial Automation: In automated production lines, injection molding machines, hydraulic presses, and other equipment, this proportional valve can be used to control the displacement, speed, and force of hydraulic cylinders, enabling programmable control of complex movements. Its high-precision control capability significantly improves production efficiency and product quality.
Construction machinery: In construction equipment such as excavators, cranes, and concrete pump trucks, this valve is used to control the operation of hydraulic motors and hydraulic cylinders, enabling precise operations. For example, in the control of a crane's telescoping boom, the proportional valve can precisely control the extension and retraction speed of the cylinder based on the input signal from the control lever, enhancing operational safety and efficiency.
Metallurgy and heavy machinery: In heavy equipment such as steel mills, rolling mills, and presses, this proportional valve can be used to control high-pressure hydraulic systems, enabling precise control of heavy-duty equipment. Its high pressure resistance and stability make it suitable for extreme operating conditions.
Testing and Simulation Equipment: In systems with high dynamic response requirements, such as hydraulic test stands, flight simulators, and automotive testing equipment, this valve provides high-frequency, high-precision hydraulic control to meet complex testing needs.
 

Advantages:

High-precision control: This proportional valve employs electro-hydraulic proportional control technology to achieve continuous, stepless regulation of hydraulic system flow and direction. Compared to traditional on/off directional control valves, it eliminates hydraulic shock and uneven operation issues, significantly improving system control precision and stability.
Fast response speed: Due to its pilot-controlled structure, this 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, this valve minimizes unnecessary energy loss. For example, under low-load conditions, the system automatically reduces flow output to reduce energy waste, enabling energy-efficient operation.
High reliability: Rexroth proportional valves are made of high-quality materials and advanced manufacturing processes, featuring 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.
