Dual fluid dispensing valve (precise micro-dosing)

Model : GS-DU28004-SQ
By combining different or identical single fluid machine valves, different dispensing volumes and mixing ratios are provided.
Precise dispensing volumes are generated through the mechanism design of rotor and stator.
By adjusting the main/hardener through the controller, different ratio mixing dispensing can be easily achieved with motor speed control.
Precise and stable dispensing without pulsation, quick stoppage without dripping through back suction function.
Suitable for adhesive viscosities up to 5,000,000cps.
Combined with the "Simple Dispenser" to allow the installation of mixing tube needles for more precise and stable dispensing.
Error ≦±1%, repeatability ≧99% (tested with water, at least 2 revolutions of main/hardener dispensing)

Troubleshooting
1. When the viscosity of the adhesive used with a single fluid machine valve is greater than 5,000cps and the inner diameter of the needle is less than 0.7 mm.
  • Back suction is required to prevent dripping after dispensing, which requires additional labor.
  • Because of back suction, more waiting time is needed for dispensing at the starting point.
  • In line drawing, there may be inconsistency in line diameter between the front and back sections, especially on short lines.
2. Dual fluid machine valves must be installed with or without needles before the mixing tube:
  • The larger the viscosity of the adhesive, the more back suction is required to prevent dripping after dispensing.
  • The longer the mixing tube, the more difficult it is to stop dispensing after dispensing, and the easier it is to drip.
  • Excessive back suction may cause the risk of mixing and solidification blockage at the outlet of the main/hardener of the dual fluid machine valve.
Advantages of adding the "Simple Dispenser":
1. No need for back suction, immediate stoppage without dripping.
2. More stable dispensing volume, better dispensing repeatability.
3. Shorter waiting time at the starting point during line drawing, maintaining consistent line diameter from start to finish.
4. Disposable accessories, no cleaning issues.
5. Modular design, compatible with single fluid, dual fluid, or dynamic mixing of dual fluid.
Controller
1. Integrated, no need for an additional controller.

2. Integrated operation interface screen for convenience.
