SET (San-ei Tech)
Needle Valve
The SV59MD is a microdot dispense valve with excellent high-speed driven capabilities, designed for consistent minimum volume dispensing in microdot applications. It can apply small to extremely minute dots and achieves its highest performance when combined with an optional high-speed solenoid valve, which ensures precise and drip-free operation. The valve operates as input air pressure retracts the piston needle from the hub of the dispensing tip to permit fluid to flow; once the cycle is completed, a spring returns the piston needle to shut off the fluid. It is designed for use with GP Needle tips ranging from 23G (ID: ø0.33mm) to 33G (ID: ø0.11mm).

How the Valve Operates
Air pressure retracts the piston needle from the hub of the dispending tip, allowing fluid to flow (Figure 1). When the cycle completes, a spring returns the piston needle to its seated position, shutting off fluid flow (Figure 2).
