Product details

Directional Proportional Valve, also known as Proportional Directional Valve, is a commonly used control element in hydraulic control systems. It can regulate the flow rate of the hydraulic system by adjusting the position of the valve spool, thus controlling the speed and direction of movement of the actuator.

Specifically, the working principle of the Directional Proportional Valve is to achieve throttling control of the flow rate through electronic control. By replacing the original control part of conventional pressure valves, flow valves, and directional valves with a proportional solenoid, it can continuously and proportionally control the pressure, flow rate, or direction of the oil flow based on the input electrical signal, enabling remote control. This allows the Directional Proportional Valve to exhibit excellent control precision and dynamic characteristics, although it may not be suitable for applications requiring extremely high precision.

The advantages of the Directional Proportional Valve include high precision, good energy efficiency, and high automation. It can precisely control parameters such as the speed, position, and force of the actuator, demonstrating high precision and stability. Additionally, it can adjust the flow rate and pressure according to demand, avoiding excessive heat generation and cooling losses, thereby improving energy utilization. Furthermore, the Directional Proportional Valve can automatically adjust based on different working conditions, eliminating the need for manual intervention and enhancing the automation level of the equipment.

However, the Directional Proportional Valve also has some disadvantages. Firstly, its price is relatively high compared to traditional hydraulic components such as check valves and cartridge valves. Secondly, due to its complex structure, installation requires certain professional knowledge and technical support. Finally, if the Directional Proportional Valve malfunctions, due to the complexity of its advanced technology, the repair difficulty will also be relatively high.

Before installing the Directional Proportional Valve, it is essential to clean it to ensure its normal operation. Additionally, attention should be paid to its maintenance and care to extend its service life and ensure stable performance.
