Product Description

Product Overview

This corrosion resistant piezoelectric jetting valve is built for long-term, low-maintenance use in industrial environments where fluids can be aggressive. It delivers consistent micro-drops with minimal cleaning and stable performance over long runs. Choose this valve when you need reliable precision dosing in harsh conditions.


Problem 

Industrial lines often face downtime and extra labor when valves corrode, clog, or require frequent cleaning, reducing throughput and increasing cost.


Cause 

Exposure to aggressive fluids, moisture, or contaminant build-up accelerates wear on wetted parts and nozzles. Standard materials and open fluid paths allow chemical attack and deposits that change droplet behavior and require more maintenance.


Solution 

This valve uses corrosion-resistant wetted parts and a compact, smooth fluid path to reduce deposit formation and simplify cleaning. The design lowers maintenance intervals and keeps droplet volume steady, so production runs longer with fewer stops. Benefits include:

  • Reduced frequency of nozzle cleaning and replacement
  • Stable droplet volume and placement over long runs
  • Better uptime in moist or mildly corrosive environments
  • Straightforward maintenance with replaceable nozzle inserts

Application

  • Chemical handling lines: precise dosing of adhesives, sealants, or protective coatings that have some corrosive components.
  • Electronics in humid production: applying adhesives or coatings where moisture exposure is common.
  • Small motor and coil assembly: controlled glue spots where corrosion resistance reduces downtime.
  • General industrial assembly: any process needing long run times and limited maintenance access.


How It Works

Conclusion: corrosion resistance and smooth fluid path keep jetting stable with less cleaning. The valve uses a piezo actuator to create a rapid pulse that ejects a precise micro-drop through the nozzle. Corrosion-resistant wetted parts and a short, unobstructed fluid channel reduce deposit buildup and maintain nozzle shape. Proper inlet pressure and pulse tuning set droplet size and repeatability.


How To Choose

Conclusion: select based on fluid chemistry, droplet size, and maintenance access.

Steps:

  1. Provide fluid chemical data and working temperature so we can recommend wetted materials (316L, PTFE, ceramic).
  2. Confirm target droplet volume and choose nozzle diameter that matches the nL range.
  3. Check viscosity at process temperature; if above 100,000 cps request a sample test.
  4. Verify required cycle rate to confirm jetting frequency needs.
  5. Decide protection level for controller and mounting if your line is wet or dusty.
  6. Plan spare nozzle and simple cleaning steps into maintenance schedule to maximize uptime.


FAQ

Q1: Can this valve handle moderately corrosive fluids?

A1: Yes. With appropriate wetted material options, it handles many moderately corrosive fluids. Send your fluid spec for verification.

Q2: How often will we need to clean the nozzle?

A2: Cleaning frequency depends on fluid solids and use. Typical runs show extended intervals vs standard valves, but inspect nozzles per your shift schedule and keep spares ready.

Q3: What droplet sizes can we expect?

A3: Typical stable drops range from 1 nL up to several hundred nL depending on nozzle and settings. We can help tune settings for your target volume.

Q4: Do you offer sample testing with our fluid? 

A4: Yes. Send your fluid data sheet and process temperature to request a sample trial. We return test logs and recommended settings.
