2.2
Theory of Operation
The LOCTITE product is transported through a product feedline
4
of PTFE to the Pinch Valve by the
dispensing pressure in the product reservoir. An additional tubing protects this product feedline. The
dispensing takes place by the opening of the Pinch Valve. A single action cylinder is used as the
actuating assemble
7
. The control unit controls the dispensing either according to a set dispensing
time or as long as the start signal is present.
In the inactive position, the Pinch Valve is closed. The cylinder piston of the actuator assembly
7
pinches the product feedline
4
together with spring pressure.
The Pinch Valve is also capable of dispensing the smallest of quantities. For this purpose, the stroke of
the cylinder piston can be limited with the hexagon socket set screw
8
.
The amount of product dispensed is controlled by:
– The amount of pressure in the reservoir.
– The length of time the shutoff valve remains open.
– The stroke of the shutoff piston in the actuator assembly.
– The dispensing needle
