This precision dispensing valve is built for fine needle applications such as FPC connector pin dosing. It delivers a stable flow up to 6 mL/min, precise per‑shot control for small deposits, and is driven by a brushless servo motor for reliable, low-drift operation. The compact head mounts on robot end effectors and supports quick nozzle changes and easy cleaning.
Many FPC connector pin operations suffer from inconsistent dot size or nozzle clogging, causing poor contact, rework and slower line speed.
Variation comes from unstable feed, pressure pulses, wrong nozzle choice or insufficient drive control. Needle tips and small pads magnify small volume errors into functional failures.
This valve uses volumetric feed with a brushless servo drive and a short fluid path to give steady output, fine shot control and reduced stringing. Standard needle adapters and quick-change nozzles make it easy to match pad size. The unit is designed for robotic workcells and inline production with minimal setup time.

The brushless servo turns a volumetric feed or auger to move fluid at a controlled rate. For single shots, the controller runs a timed pulse to deliver the target deposit. The short fluid path and servo control reduce pressure ripple at the nozzle, producing consistent drops and less stringing. Nozzle size and pulse time set shot volume and bead width.
Q1: What is the smallest deposit I can run reliably?
A1: Typical minimum deposits are around 5 µL with correct nozzle and tuning; production stability requires bench tuning.
Q2: Can it mount on a pick‑and‑place or dispensing robot?
A2: Yes. The compact flange and encoder/driver options are designed for robot end effector mounting; provide your robot interface for confirmation.
Q3: What nozzle/needle types are supported?
A3: Luer/needle adapters and standard nozzles (Ø 0.25/0.4/0.7 mm) are supported; custom outlet fittings available on request.
Q4: How often will the nozzle clog with flux or adhesive?
A4: Clogging depends on fluid solids and duty cycle. Using the right nozzle, steady feed and occasional purge reduces clogging; quick head access shortens maintenance time.
Q5: Do you offer sample testing?
A5: Yes. Send fluid spec (viscosity at working temp), needle size and desired deposit; we will run a test and return results and recommended settings.
