Precision Electronics Jetting Valve — Piezo Jet Valve Jetting System up to 1200

Product Specification

Product Overview

This precision jetting valve and driver system supports continuous operation at high speed with consistent droplet delivery for electronics manufacturing. It is built for stable micro-droplet placement when high throughput and tight volume control are required. Use it in automated lines where repeatable, clean jetting is essential.

Problem

High-speed production lines often suffer from inconsistent droplet size and placement when valves cannot keep up with cycle demands. This leads to rework, lower yield, and extra material use.

Cause

At high pulse rates, valves with less stable drive control or less robust fluid paths show varying droplet volume and occasional miss-shots. Variations come from timing in the drive signal, fluid compressibility, and nozzle wear under frequent cycling.

Solution

This jetting system combines a responsive piezo actuator and a controlled drive signal to enable stable ejection up to 1200 Hz. The fluid path uses corrosion-resistant materials to reduce fouling and extend service life.

Key outcomes:

Consistent droplet volume at high frequency
Reduced nozzle clogging and maintenance
Smooth integration with automated dispensing systems
Repeatable placement for fine-pitch electronics work

Technical parameters

Application

• High-speed electronic assembly: selective coating, flux or adhesive deposition on PCBs.
• Micro-dispensing: tiny volumes for sensor or connector manufacturing.
• Automated production: inline dosing where cycle times are short and placement accuracy matters.
• Lab and R&D lines: quick switching between small samples and pilot runs.

How It Works

A piezo actuator generates fast pressure pulses in the fluid chamber; each pulse forms and ejects a micro-droplet through the nozzle. The timing and amplitude of the pulses determine droplet size and interval. A stable fluid path and controlled inlet pressure keep jetting reliable at high repetition rates.

How To Choose

• Required speed — choose this 1200 Hz model if your cycle needs exceed standard valves and you need higher throughput.
• Volume per shot — match nozzle size and drive settings to your target nL range.
• Fluid type — confirm fluid compatibility with 316L, PTFE, or ceramic options; provide your fluid spec for testing.
• Pressure supply — ensure your air or pump system can maintain stable inlet pressure in the specified range.
• Integration — check physical mounting and electrical connector compatibility with your machine.
• Maintenance plan — for continuous high-frequency use, plan nozzle inspection and replacement intervals.

FAQ

Q1: Can the valve run continuously at 1200 Hz?

A1: The valve is designed for high-frequency operation; continuous use at 1200 Hz should be validated with your fluid and cooling conditions. Contact us for a process trial.

Q2: What droplet sizes can I expect?

A2: With recommended nozzle sizes and drive settings, droplet volumes typically range from 3 nL to 150 nL. Exact volume depends on nozzle and pulse amplitude.

Q3: How to confirm fluid compatibility?

 A3: Send a material safety or specification sheet for the fluid. We can run a sample test and report compatibility and recommended wetted material.

Q4: Is the system easy to integrate with a dispensing robot?

A4: Yes. The compact flange and standard electrical connector simplify mounting and control integration. Provide machine interface details for a smooth setup.

Q5: What support is available for tuning the system?

A5: Our applications engineers can run parameter tuning, recommend drive settings, and assist on-site or remotely with setup.
