What is an Injection Valve?

[LaBrantley]

An injection valve utilizes the characteristics of piezoelectric materials to generate mechanical force through voltage. When the lower piezoelectric material is charged, the valve opens; when the upper piezoelectric material is charged, the valve closes. Due to the extremely small space for opening and closing the valve and the high frequency of action, it can inject a very small amount of liquid material at high speed. Below is more information about injection valves: 1. Working parameters: (1) Non-contact injection, high precision, multifunctional. (2) Applicable liquid viscosity up to 2,000,000 mPas. (3) Maximum speed up to 1,000 times per second. 2. Working principle: Piezoelectric injection dispensing utilizes the inverse piezoelectric effect of piezoelectric materials, featuring high injection frequency, simple equipment structure, and the ability to obtain glue dots as small as 100 microns in diameter.
