Load-sensing proportional control valve is an important component in hydraulic system. It can convert load information into precise control signal and realize precise regulation of hydraulic system. The working principle of this valve is based on load sensing technology and proportional control technology. By real-time monitoring of load pressure, the valve opening is automatically adjusted to achieve precise control of flow.
In hydraulic system, changes in load often lead to changes in pressure. Load-sensing proportional control valve monitors load pressure in real time through built-in sensor and converts this information into electrical signal. This electrical signal is then sent to the proportional controller, and after processing, it outputs a control signal proportional to the load pressure. This control signal acts on the proportional solenoid to generate corresponding magnetic force, push the valve core to move, and thus change the opening of the valve port.
The change in the opening of the valve port directly affects the flow in the hydraulic system. When the load increases, the load-sensing proportional control valve will automatically increase the opening of the valve port to increase the flow and meet the load requirements. On the contrary, when the load decreases, the opening of the valve port will decrease accordingly, reducing the flow and avoiding energy waste. This automatic adjustment process enables the hydraulic system to always maintain the working pressure and flow that match the load, improving the efficiency and stability of the system.
The advantage of the load-sensing proportional control valve is that it can achieve precise load adaptation and flow control. No matter how the load changes, the system can respond quickly and adjust the flow to meet the demand. This not only improves the response speed of the system, but also reduces energy consumption and extends the service life of the equipment.
In addition, the load-sensing proportional control valve also has the characteristics of simple structure, easy maintenance and high reliability. The advanced proportional solenoid and sensor technology are used inside, making the performance of the valve more stable and reliable. At the same time, the design of the valve body also takes into account the needs of easy installation and maintenance, reducing the user's operation and maintenance costs.
In summary, the load-sensing proportional control valve is a key component for achieving precise control in the hydraulic system. It monitors the load information in real time and automatically adjusts the opening of the valve to achieve precise control of the flow, providing a strong guarantee for the stable operation of the hydraulic system.
