KGN Needle valve is a air operated valve. Valve is on when pressure is over 0.39MPa and off by a built-in spring. 
Using with dispense controller and pressure tank, the shot volume can be controlled to a very small amount by adjusting
the material delivery pressure and the valve opening time. This valve is suitable for middle to high viscosity materials dispensing.
