High Temperature Resistant Material PUR Piezo Valve with Luer Connector​

Principle & Control

PUR Piezo Valve

1. The PUR Piezo valve is composed of several modules: a barrel heating module, a pressurized cap module, a nozzle heating module, a runner module, a valve body module, and a heat dissipation module.
2. The barrel heating module supports the barrel and features a controllable heating section for the initial warming of the gel.
3. The pressurized cap module ensures the barrel is sealed and pressurized, adjusting the output pressure through a controller.
4. The heat dissipation module is responsible for dissipating heat and reducing noise emitted by the valve body.
5. The Piezo-electric injection valve adopts a modular design, where the gel-contacting part is the runner module and the non-contacting part is the valve body module.
6. Based on specific applications, the runner module can be replaced to meet different dispensing needs.
7. Nozzle diameters vary from 0.03MM to 0.80MM and come in flat jet, needle, and extension styles.
8. Runner modules need regular cleaning in an ultrasonic cleaner. It's crucial to avoid immersing seals in organic solvents and to use specialized tools for nozzle cleaning to prevent damage.

Piezo Valve Controller

1. The touch screen operates the piezoelectric injection valve and dispensing system, supporting robust, safe, and reliable 485 communication for control.
2. The touch screen features a graphical control interface that clearly and intuitively displays the dispensing system components and control functions.
3. Nozzle Heating Device: Before dispensing, it's necessary to heat the nozzle to an appropriate temperature using the single-stage heating mode of the heating device.
4. Maintaining a constant temperature at the nozzle ensures optimal gel performance by preserving its best qualities.

Nozzle and drum heating

1. Prior to glue dispensing, the nozzles undergo a two-stage heating process to reach an appropriate temperature.
2. Maintaining a consistent temperature for the glue by heating both the barrel and the nozzle ensures its optimal performance.
