NEEDLE VALVE SV51MD SAN-EI-TECH

High-precision needle valve for stable and consistent microdot dispensing of low-viscosity fluids from San-Ei Tech.

Model: SV51MD

Dispenses ultra-trace volumes down to 1 microliter with exceptional accuracy.
Suitable for low-viscosity fluids such as epoxy, flux, oil, ink, solvent, and UV-curable adhesives.
Drip-free shutoff with a needle-penetrating tip structure that stops fluid right at the nozzle end.
Excellent liquid drainage thanks to the seal positioned close to the nozzle, ensuring stable output.
Chip-stop mechanism prevents fluid curing and clogging.
Ideal for micro-coating and precise dispensing in automated assembly lines.
Adjustable fluid volume for fine-tuning application.
Achieves high-speed response and stable discharge when combined with an SVEM solenoid valve, enabling stable dispensing at 50 Hz cycles.
