The unique advantages of piezoelectric dispensing valves

Piezoelectric dispensing valve is a high-precision and high-efficiency liquid control equipment widely used in precision dispensing processes. This valve utilizes the piezoelectric effect to achieve precise liquid injection and has many unique advantages, making it an important technological innovation in the dispensing field. JEENOCE will provide a detailed introduction to the unique advantages of piezoelectric dispensing valves.

1、 High precision liquid control

The piezoelectric dispensing valve adopts high-precision piezoelectric ceramic material as the driving element, and changes the size of the ceramic by applying voltage to control the flow of liquid. This mechanical deformation can achieve weak liquid flow control, allowing the dispensing valve to spray liquid with extremely high accuracy, ensuring precise distribution of glue and accuracy of dispensing position. Compared to traditional pneumatic dispensing valves, piezoelectric dispensing valves have higher accuracy and stability in liquid control.

2、 Fast response speed

Due to the special properties of piezoelectric ceramic driving mechanisms, the response speed of piezoelectric dispensing valves is very fast. When a voltage is applied, piezoelectric ceramics can instantly expand or contract, achieving rapid injection or cessation of liquid. This fast response capability makes piezoelectric dispensing valves suitable for high-speed dispensing operations and enables efficient production line automation.

3、 No need for compressed air

Compared with traditional pneumatic dispensing valves, piezoelectric dispensing valves do not require compressed air as a power source. This brings two significant advantages: reducing noise and vibration in process equipment, improving the quietness and comfort of the working environment; Eliminated reliance on compressed air systems, simplified equipment structure, and reduced maintenance and operating costs.

4、 Adjustable injection pressure and flow rate

By adjusting the voltage applied to the piezoelectric ceramic, precise adjustment of injection pressure and flow rate can be achieved. This flexibility makes the piezoelectric dispensing valve suitable for various liquid adhesives with different viscosities, and can meet the coating effects of different process requirements.

5、 Long lifespan and stability

Piezoelectric ceramic materials have good mechanical properties and stability, and can maintain efficient working conditions during long-term use. Compared with other types of driving components, piezoelectric dispensing valves have a longer service life and reduce the frequency of equipment maintenance and replacement.
