Loctite Dispense Valve 97114 User Manual

For most dispensing tasks, the air outlet chokes should be completely open. The air outlet chokes
must be adjusted when:

– Very low viscosity (thin bodied) adhesive is dispensed or:
– An extremely exact point or bead application is required.

The air outlet chokes are provided to slow the actuation
speed of the valve. The air outlet chokes, used on this
valve, allows air to free flow into the actuator and controls
the rate at which the exhaust air is metered out of the
actuator. Refrerring to Figure 1 the air outlet choke 8
allows pressurized air into the actuator, which shuts off
product flow. Air outlet choke 9 allows air into the actuator
to open the valve thus allowing product to flow through
the valve.

For most applications the air chokes should be set for
maximum airflow. Maximum flow is achieved by turning
the adjustment screw all the way in a counterclockwise
direction.

For bead dispensing it may be helpful to open the valve
slower to improve bead consistence from start to finish.
This is done by:

1. Locate air choke 8.
2. Turn adjustment screw all the way in a clockwise direction.
3. Turn adjustment screw one or two revolutions in the counterclockwise direction.
4. Actuate the valve and observe speed at which the valve opens.
5. Repeat steps 3 and 4 until valve is operating at desired speed.

For dispensing acrylic adhesive slowing the shut off speed of the valve may reduce micro bubbles
from forming within the product chamber of the valve. This is done by:

1. Locate air choke 9.
2. Turn adjustment screw all the way in a clockwise direction.
3. Turn adjustment screw one or two revolutions in the counterclockwise direction.
4. Actuate the valve and observe speed at which the valve opens.
5. Repeat steps 3 and 4 until valve is operating at desired speed.
