4.4 INSTALLATION- TS1212 MICRO SHOT VALVE OPTION
1. With Valve mounted as referred to in Section 4.3 Number 4, connect the Luer Lock Fitting at the end of the
Dispense Tube onto the inlet side of (7) Pinch Tube on the TS1212 Valve with twisting action (Refer to figure 5).
2. Install the Air Line (10) from the valve to an Air Source or optional TS9701 Varimeter as referred to in Section 4.3
Number 3 (Refer to figure 5).

3. Install Dispensing Needle into Luer Lock Fitting on exit side of (7) Pinch Tube on Valve with twisting action. (Refer
to figure 6)
Note: Small-bore needles provide better flow control of thin materials.
4. Open Air Pressure Regulator Knob and very slowly turn Knob clockwise to adjust air pressure to 3 psi.
CAUTION: Air must be purged completely from Dispensing Valve or Valve will not instantly shut off material
flow.
5. To purge air from the supply line, place a disposable container under the needle (Refer to figure 7). Activate Valve
with 30 psi min. air pressure from air source or optional TS9701 Varimeter, dispense adhesive for 15 to 20
seconds or until air is purged from the line. Deactivate Valve (Release air pressure). If Valve does not instantly
shut off flow, air is not completely purged from the line.
6. It may be necessary to fine tune the flow control or dot size desired. Adjustment of the Knob (5) controls the travel
of the “SHUT-OFF” Piston (2) by limiting its reverse movement. The “SHUT-OFF” Piston is moved by the Push
Rods of the Air Piston (8). The travel of the “SHUT-OFF” Piston (2) determines the amount of opening for the
Pump Tube (7), when coupled with a *time control, determines the shot size. (Refer to Section 4.3 number 3). With
repeated use, a closely controlled application can be achieved by adjusting the following:
A. Pressure on the supply reservoir.
B. Needle tip size
C. Stroke adjustment on the shut-off Piston Knob (5).
