Poppet valve is a pneumatically operated valve.
valve is on when pressure is over than 0.30MPa and off by a built-in spring.
When use 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. Valve has"suck back effect" 
to suck back the material before the valve is off.
