Rexroth DB20-1-5X/100X Proportional Valve - 100 Bar, Blue, Electric

Product Specification

Description:

The Rexroth Proportional Valve DB20-1-5X/100X is a high-performance pilot-operated proportional pressure valve manufactured by Bosch Rexroth in Germany. This valve belongs to the proportional control valve series and can continuously and infinitely adjust the pressure of a hydraulic system based on the input electrical signal. This valve is a pilot-operated proportional pressure valve with a nominal bore of 20 mm. It features single-stage pilot control. This valve belongs to the 5X series, featuring specific electrical interfaces and control characteristics. The valve has a rated pressure of 100 bar. The valve employs a pilot-controlled structure, where the position of the pilot valve spool is adjusted by the magnetic force generated by the proportional solenoid, thereby controlling the opening of the main valve spool to achieve precise regulation of hydraulic system pressure. This design enables the valve to continuously adjust pressure in response to changes in the input electrical signal, thereby avoiding the hydraulic shock issues associated with traditional on/off valves.
 

Application Areas:

The Rexroth Proportional Valve DB20-1-5X/100X, with its high performance and flexibility, is widely used in multiple fields:
Industrial Automation: In industrial automation systems, this valve is used to precisely control the pressure of hydraulic cylinders or hydraulic motors, enabling smooth and precise operation of equipment. For example, in injection molding machines, hydraulic presses, and other equipment, the valve can adjust pressure in real-time according to process requirements, ensuring product quality and production efficiency.
Construction Machinery: In construction machinery such as excavators and cranes, this valve is used to control the pressure of the hydraulic system, enabling precise control of hydraulic cylinders and hydraulic motors. For example, during the boom extension and lifting processes of a crane, the valve can adjust pressure in real-time based on load changes, ensuring smooth and safe operation.
Metallurgy and heavy machinery: In heavy machinery such as rolling mills and presses, this valve is used to control high-pressure hydraulic systems, ensuring stable operation of the equipment under high loads. Its high pressure resistance and stability enable it to operate stably for long periods under extreme conditions.
Testing and Simulation Equipment: In systems with high dynamic response requirements, such as hydraulic test stands and flight simulators, this valve provides high-precision pressure control to meet complex testing and simulation needs.
 

Advantages:

High-Precision Control: This valve uses a proportional solenoid valve for control, enabling continuous, stepless pressure adjustment based on input electrical signals. Compared to traditional on/off 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, the 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 system pressure, the 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.
