This narrow jetting valve is designed for precise placement of UV curable adhesives and small-volume deposits in lens assembly and compact optical modules. It fits into tight tool heads and delivers repeatable dots and short lines with low variation. Use it when you must avoid overflow, control glue amount, and keep cycle times short.
In lens assembly and optical modules, excess glue or poor placement causes optical defects, extra polishing, or rework that reduce yield and increase cost.
Large valve bodies, inconsistent droplet control, or poor nozzle access make accurate glue placement difficult. UV glue needs precise dose and position; if the valve cannot form small stable drops in narrow spaces, glue spreads or bridges parts.
This narrow jetting valve combines a slim profile with controlled pulse ejection to place small droplets and short beads precisely. It reduces overflow and improves first-pass yield for lens bonding tasks.

Conclusion: small droplets are formed by short, fast pulses and a stable fluid feed. The valve uses a rapid actuator stroke to push a controlled amount of fluid through a narrow nozzle. Pulse width and amplitude set droplet size while steady inlet pressure keeps the fluid meniscus steady. For UV glues, keep light exposure controlled until after placement.
Conclusion: choose the valve based on droplet size, glue viscosity, and space constraints.
Steps:
Q1: Can this valve handle UV-curable adhesives reliably?
A1: Yes. With proper wetted material choice and tuning, it handles common UV glues. We recommend a sample test for your specific glue.
Q2: What is the smallest dot I can expect in production?
A2: Typical stable dots start around 0.8 nL with the right nozzle and drive settings. Production tuning is necessary for consistent output.
Q3: How do I avoid premature curing during dispensing?
A3: Keep UV exposure off the work area until after placement, use UV-safe lighting, and limit stray light near the nozzle. We can advise on best practices.
Q4: How often should the nozzle be cleaned or changed?
A4: Cleaning frequency depends on glue solids and use. For clear UV glues, routine inspection and cleaning every shift or as needed is common; filled glues require more frequent attention.
Q5: Do you provide sample testing with our adhesive?
A5: Yes. Send your glue spec and process temperature and we can run a short trial and return results.
