Automated Dual Piezo Jetting Valve with 10 Channel Parameters for High Precision

Product Overview

This automated dual piezo jetting valve offers two independent dispensing channels with ten adjustable parameters per channel for tight process control. It is intended for automated production lines where precise dosing, repeatable placement, and quick tuning are required. Choose this valve when you need flexible control and fast on-line adjustment for different fluids or tasks.

Problem

Automated lines often need to handle different fluids or change settings quickly between jobs, and single-parameter valves limit tuning flexibility. Poor control leads to inconsistent drops, extra setup time, and downtime for rework.

Cause

If each valve channel lacks enough adjustable settings, operators must trade off speed for accuracy or perform frequent manual adjustments. Inconsistent fluid feed or insufficient control over pulse and timing makes it hard to keep repeatable results across shifts or batches.

Solution

This dual-channel system provides ten controllable parameters per channel, including pulse width, pulse amplitude, delay, and others, so you can fine-tune jetting for each fluid and each cycle. The result is faster setup, closer control of drop volume and timing, and lower scrap rates. Key benefits:

• Two independent channels for dual-fluid or paired dispensing tasks
• Deep parameter control for fast tuning and repeatable results
• Compact body designed for easy robot or gantry mounting
• Reduced line stops and faster changeovers between jobs

Application

Paired dispensing on PCBs: primer and adhesive in the same pass to reduce steps.
Dual-color or multi-step filling where one channel lays a base and the other adds a tracer.
Automated assembly lines that switch products frequently and require quick re-tuning.
Small module production where two matched drops must be placed close together.

How It Works 

Conclusion: precise output comes from independent pulses and matched fluid paths for each channel. Each channel has its own actuator and parameter set. The controller times pulses and sets amplitudes so you can tune drop size, interval, and sequence. Stable inlet pressure and matching nozzle geometry help keep meniscus control and repeatable shots. Use pre-pulse or recovery time settings to avoid stringing with challenging fluids.

How To Choose 

Conclusion: pick this dual valve when you need two independent outputs and deep tuning for fast setup. Steps:

Decide if you need two simultaneous flows or one flow plus a second material; select channels accordingly.
Provide fluid specs (viscosity at process temperature, solids) for both fluids to determine wetted parts and nozzle choice.
Set your target droplet sizes and match nozzle diameters to those volumes.
Confirm required cycle rate and ensure the valve and driver handle the throughput.
Check mounting space and flange compatibility with your robot or gantry.
Plan a short on-site or lab trial to lock in the 10 parameter settings for each channel.

FAQ

Q1: Can the two channels be set completely independently?

A1: Yes. Each channel has its own set of parameters so you can run different fluids or different drop sizes at the same time.

Q2: What are typical parameters I can adjust for each channel?

A2: Common adjustable items include pulse width, pulse amplitude, delay, frequency limit, pre-pulse pressure, and recovery time. We will provide a parameter guide with recommended starting values.

Q3: What is the fastest I can run both channels?

A3: Typical maximum is up to 1000 Hz per channel, but actual usable speed depends on fluid viscosity and nozzle choice. We recommend sample validation at your target rate.

Q4: How do I integrate this valve with my robot controller?

A4: The valve has a compact flange and standard electrical connectors; provide your robot interface details and we will advise on mounting and control wiring.

Q5: Do you support tuning on site?

A5: Yes. Our applications team can assist remotely or onsite to tune parameters and run sample tests.
