Adopting Modular PUR Piezo Valve Design with Stainless Steel 303, Special Steel

Adopting Modular PUR Piezo Valve Design with Stainless Steel 303, Special Steel​

Principle & Control

Piezo Injector Valve:
1. Adopting modular design, the part in contact with the gel is designed as runner module and the part not in contact with the gel is designed as valve module.

2. In different applications, the runner module can be replaced to meet the dispensing needs.

3. Nozzle diameters (from 0.03MM to 0.80MM) are categorized into flat jet, needle, and extension nozzles.Runner modules need to be cleaned regularly in an ultrasonic cleaner. Seals should not be immersed in organic solvents. Special tools are required to clean the nozzles to prevent damage to the nozzles.

4. When the runner sealing surface accumulates colloid crystals, prohibit the use of sharp objects to remove the crystalline layer to prevent scratching the sealing surface.

5. In order to avoid the crystallization of colloid in the runner, coagulation, clogging, in the specific application, please consult our technical staff, select the correct runner module.

Piezo Valve Controller:

1. The touch screen controls the piezoelectric injection valve and dispensing system, supports 485 communication, powerful, safe and reliable.

2. The touch screen adopts graphic control mode, the components of dispensing system and the control display function are displayed graphically, which is concise and intuitive.

Nozzle heating device:

1. The nozzle is required to be heated to a suitable temperature before dispensing. The heating device adopts one-stage heating mode.

2. Heating at the nozzle maintains the constant temperature of the gel to meet the best performance of the gel. The best performance of the colloid.
