dispensed. Simultaneous with the action of the Upper Piston (Figure 7, A), the blunt Lower
Piston (Figure 7, D) moves forward until it stops against the Adjusting Screw (Figure 7, E). This
causes the piston to partially occlude the Tubing (Figure 7, B).

Shut Off

When the valve is at the end of its dispense cycle, the actuating air exhausts. The upper piston
spring moves the Piston (Figure 7, A) forward where it pinches the Tubing (Figure 7, B). At
precisely the same moment, the blunt Lower Piston (Figure 7, D) is released so that its spring
can also return to its original position. The lower portion of the tube (Figure 7, B) returns to its
normal (open) shape. Suck-back is created from the change in the tubing shape. The valve is
now ready to repeat the cycle. Fine adjustments can be made to both flow rate and suck-back
to obtain the required results.
