Product Specification

Description:

The Rexroth Proportional Valve DBW20B2-5X/315-6EG24N9K4 is a high-performance electro-hydraulic proportional pressure control valve manufactured by Bosch Rexroth, a German company. This valve features a pilot-operated design, enabling continuous, stepless regulation of hydraulic system pressure through input signals from an electromagnetic coil. Its key features include high-precision pressure control, rapid response capability, and broad applicability, making it suitable for various applications such as industrial automation, construction machinery, and metallurgical equipment. The proportional valve has a nominal bore of 20 mm, a maximum operating pressure of 350 bar, and a maximum flow rate of 650 L/min. Its electrical interface uses a 24V DC power supply and is controlled via an electromagnet, enabling seamless integration into automated control systems.
 

Application areas:

Industrial automation: In the field of industrial automation, the Rexroth Proportional Valve DBW20B2-5X/315-6EG24N9K4 can be used to control the pressure of hydraulic cylinders or hydraulic motors, achieving precise force control and speed control. For example, in injection molding machines, this valve can precisely control the opening and closing speed and pressure of the mold, ensuring the stability of the molding process and product quality.
Construction Machinery: In construction machinery, such as excavators and cranes, this proportional valve can be used to control the pressure of hydraulic cylinders and hydraulic motors, enabling precise operations. For example, during the extension and lifting of a crane's boom, the proportional valve can precisely control the pressure of the hydraulic cylinder based on input signals from the control handle, ensuring smooth movement of the boom.
Metallurgy and heavy machinery: In metallurgical equipment and heavy machinery, this proportional valve can be used to control high-pressure hydraulic systems, enabling precise control of heavy-duty equipment. For example, during the rolling process of a rolling mill, the proportional valve can precisely control the pressure of the rollers, ensuring rolling quality and the stability of equipment operation.
Testing and Simulation Equipment: In systems with high requirements for dynamic response, such as hydraulic test stands, flight simulators, and automotive testing equipment, this proportional 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 pressure. Compared to traditional on/off relief 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 pressure switching. Its dynamic response characteristics meet high-frequency control requirements, enhancing overall system efficiency.
Energy-Efficient and High-Performance: By precisely controlling hydraulic oil pressure, this valve minimizes unnecessary energy loss. For example, in low-load conditions, the system automatically reduces pressure 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.
