DBEM20-71/200YG24K4M Hydraulic Proportional Valve
Detailed Content
The DBEM20-71/200YG24K4M Hydraulic Proportional Valve, a product of the Rexroth brand, combines advanced proportional control technology with the functionality of a relief valve, enabling precise control and regulation of hydraulic system pressure. This valve is suitable for various applications requiring precise hydraulic pressure control, such as engineering machinery, metallurgical equipment, shipbuilding, and other fields.
I. Basic Overview
The DBEM20-71/200YG24K4M Hydraulic Proportional Valve controls the position of the valve spool through an electromagnet, thereby changing the valve opening to control and regulate the flow rate in the hydraulic system. When the input signal to the electromagnet changes, the position of the valve spool also changes accordingly, altering the flow area of the valve port so that the hydraulic system pressure is proportional to the input signal. Additionally, this valve has a relief function that allows excess hydraulic oil to flow back to the reservoir when the system pressure exceeds the set value, maintaining a constant system pressure.
II. Working Principle
By utilizing proportional control technology, the DBEM20-71/200YG24K4M Hydraulic Proportional Valve achieves precise control and regulation of hydraulic system pressure. The compact and well-designed valve structure ensures good stability and reliability. The rapid position change of the valve spool controlled by the electromagnet allows the valve to quickly respond to changes in the input signal. The valve's adjustable set pressure meets the operational requirements of different working conditions, and it features overload protection that automatically activates the relief function when the system pressure exceeds the set value, protecting the hydraulic system from damage.
III. Main Features
1. High-Precision Control: Utilizes proportional control technology to achieve precise control and regulation of hydraulic system pressure.
2. Good Stability: The valve's compact structure and reasonable design provide good stability and reliability.
3. Fast Response Speed: The electromagnet controls rapid changes in the valve spool's position, enabling the valve to quickly respond to input signal changes.
4. Wide Pressure Regulation Range: The valve's set pressure can be adjusted according to actual needs to meet the requirements of different working conditions.
5. Overload Protection: Automatically activates the relief function when the system pressure exceeds the set value, protecting the hydraulic system.
IV. Application Fields
The DBEM20-71/200YG24K4M Hydraulic Proportional Valve is widely used in applications requiring precise control of hydraulic pressure, including:
1. Engineering Machinery: Such as excavators, loaders, cranes, etc., for controlling the movement speed and force of various actuators.
2. Metallurgical Equipment: Such as rolling mills, steel-making furnaces, etc., for controlling the extension and retraction speed and pressure of hydraulic cylinders.
3. Shipbuilding: Such as steering gears, anchor winches, etc., for controlling ship steering and mooring actions.
4. Other Fields: Such as petroleum machinery, chemical equipment, agricultural machinery, etc., also used in applications requiring precise control of hydraulic pressure.
In summary, the DBEM20-71/200YG24K4M Hydraulic Proportional Valve is a high-performance, high-precision hydraulic control component with broad application prospects and market demand.
