This concentric auger valve meters solder paste and similar pastes using a rotating screw to give controlled, repeatable output. The 500 rpm capability lets you match faster line speeds while keeping deposit volume stable. The compact head fits robot end effectors and desktop stations and features quick access for nozzle change and cleaning.
Boards and assemblies fail when solder paste deposits vary in volume or position, causing solder bridges, tombstoning, and rework.
Variation often comes from pressure pulses, air in the feed, or unstable drive control. Solder paste in particular needs positive metering and the right nozzle to form consistent deposits at production speed.
This concentric auger valve provides positive displacement metering driven up to 500 rpm so flow tracks motor speed linearly. The short fluid path and robust wetted parts reduce air traps and clogging. Use matched nozzles and tuned drive profiles to achieve consistent paste dots and fast cycle rates with less maintenance.

The concentric screw rotates to push paste forward at a controlled rate. Motor rpm sets flow; a timed motor pulse produces a fixed per‑shot volume. Because displacement is mechanical, the nozzle sees continuous, low‑pulsation supply compared with pressure pumps. Nozzle diameter and pulse time determine deposit size and shape.
Q1: Can this valve handle standard solder pastes?
A1: Yes. It is designed for solder paste dispensing when nozzle and feed are matched. Send a sample for a bench trial to confirm settings.
Q2: What is the smallest dot I can make?
A2: Smallest reliable dot depends on nozzle and paste; typical minimum is about 5 µL with fine nozzles and tuned pulses.
Q3: How often will nozzles need cleaning?
A3: Cleaning depends on paste tackiness and duty cycle. Regular short purges and one or two scheduled manual checks per shift are common on many lines.
Q4: Do you support robot mounting and control integration?
A4: Yes. The compact flange and standard electrical interfaces make robot mounting straightforward; we provide mounting drawings and driver recommendations.
Q5: Do you offer sample testing with my paste?
A5: Yes. Send paste samples and process notes; we will run a bench test and return recommended settings and a test report.
