3. Principle
The valve open air pressure forces the internal
piston to move up, and the needle to open and
permit fluid flow. When the valve close air pressure
forces the internal piston to move down, and the
needle closes, stopping the fluid flow and being
pushed a slight amount of fluid.
The amount of fluid dispensed will depend on the
time the valve is open, the viscosity of the fluid, the
air pressure in the fluid reservoir and the dispensing
tip size.
Flow rate is a function of reservoir pressure, tip
size and fluid viscosity.
Needle-off type valves have a sneakhead at the end point due to the
different of the space which is get the needle moves down. And the
valve is suitable for small amount per shot.
