This piezoelectric jetting valve is built to move thick fluids at high speed while working with a low to medium inlet pressure range. It is suitable for automated lines that need repeatable drops of high-viscosity adhesives or pastes without large pumps. Choose this valve when you need reliable high-volume transfer at modest air pressure and stable drop control.
Many lines cannot process thick adhesives quickly because valves need high pressure or frequent cleaning. Low throughput or frequent stoppage increases cost and reduces yield.
Thick fluids resist flow and need carefully matched drive energy, nozzle size, and inlet pressure. If any of these are wrong, the valve can sputter, form inconsistent drops, or clog more often.
This valve combines a robust piezo drive with a wide fluid path and nozzle options so viscous materials can be jetted reliably at 0.1–0.8 bar inlet pressure. It reduces dependency on high-pressure systems, simplifies setup, and lowers maintenance compared with narrow-path dispensers.

Conclusion: matched drive pulses, larger fluid path, and proper nozzle let thick fluids flow at modest pressure. A controlled piezo pulse creates a pressure wave that pushes a volume through the nozzle. A wider channel reduces resistance so the valve works with 0.1–0.8 bar inlet pressure while keeping droplet size stable. Tuning pulse width and inlet pressure sets the average drop volume.
Conclusion: select based on fluid viscosity, target volume, and your pressure source.
Steps:
Q1: What maximum viscosity can this valve handle?
A1: In many cases it can handle up to about 300,000 cps when nozzle size, temperature, and inlet pressure are set correctly. Please send your fluid spec for confirmation.
Q2: Can I use a basic air supply at 0.1–0.8 bar?
A2: Yes. The valve is designed to operate in that pressure window; use a stable regulator and avoid pressure dips under load for best repeatability.
Q3: What droplet sizes are realistic in production?
A3: With proper tuning, stable drops from about 2 nL up to several hundred nL are achievable depending on nozzle and fluid.
Q4: How often will nozzles need cleaning with filled pastes?
A4: Cleaning interval depends on solids and use. Filled pastes require more frequent inspection; we recommend keeping spare nozzles and a routine cleaning schedule.
Q5: Do you offer sample testing with our material?
A5: Yes. Send your fluid data sheet, working temperature, and desired drop size to market01@mingseal.com and we will arrange a trial and share results.
