DBE5 Proportional Pressure Valve
DBE5 proportional pressure valve is an electro-hydraulic proportional control element. It belongs to the proportional pressure valve series and is usually used in industrial hydraulic systems to achieve accurate and continuous adjustment of system pressure. The following is an introduction from its structure, working principle, functional characteristics and application:
1. Structural composition
The DBE5 proportional pressure valve is mainly composed of proportional solenoid, pilot valve, main valve and other parts. As the core control element, the proportional solenoid receives electrical signals and converts them into mechanical forces; the pilot valve is used for pre-regulation of the pressure to provide pilot pressure to the main valve; the main valve adjusts the system pressure according to the change in pilot pressure.
2. Working principle
When the input current (electrical signal) acts on the proportional solenoid, the solenoid generates an electromagnetic force proportional to the current, pushing the pilot valve core to move, changing the opening size of the pilot valve, thereby adjusting the pilot pressure. The pilot pressure acts on one end of the main valve core and is balanced with the spring force at the other end. The main valve core moves according to the pressure difference, adjusts the opening size of the main valve, and then controls the output pressure of the system. The system pressure is proportional to the input current. By changing the magnitude of the input current, continuous adjustment of the system pressure can be achieved.
3. Functional characteristics
Accurate control: Accurate conversion of electrical signals to mechanical forces is achieved through proportional electromagnets to ensure accurate adjustment of system pressure.
Continuous adjustment: The input current can be continuously changed, and the system pressure is continuously adjusted to meet the pressure needs under different working conditions.
Fast response speed: The dynamic response characteristics of proportional solenoids are good, and the valve has a short response time, which can quickly adapt to changes in system pressure.
High stability: Adopt advanced control algorithms and structural design to ensure that the valve can operate stably under all working conditions.
Easy to integrate: It can be integrated with PLC, DCS and other control systems to achieve remote monitoring and automated control.
IV. Application areas
DBE5 proportional pressure valve is widely used in industrial hydraulic systems, such as injection molding machines, die casting machines, hydraulic presses, engineering machinery, etc., and is used to control the pressure of the system to ensure the normal operation of the equipment and the quality of processing.
