5. SET UP INSTRUCTIONS
Refer to Figure 3.0
1. Install a new pinch tube in the valve. Following instructions in
Section 6. “Pinch tube replacement” on page 8.
2. If desired, mount the valve to the bracket included.
3. Connect fluid feed line to valve inlet port (1).
4. Install valve actuating air line to air inlet port (2)
5. Connect valve air line to an approved valve controller.
6. Set the fluid reservoir pressure. Do not exceed 60 psi (4.1bars)
7. Make sure all connections are tight
8. Place container under the valve outlet and activate the valve until the
fluid flows steady.
9. Attach appropriate dispense tip to the luer lock outlet fitting (3).
The amount of fluid that flows through the valve is determined by:
• Flow control adjustment- Turn adjustment screw (4)
counterclockwise to increase fluid flow rate and clockwise to
decrease fluid flow rate.
• Length of actuation, set at controller (Valve open time).
• Fluid reservoir pressure.
• Dispensing tip size.

PROBLEM POSSIBLE CAUSE CORRECTION
Fluid pressure too low Increase fluid pressure
Operating pressure too
low
Increase air pressure to 50 psi
(3.4 bars)
Dispense tip clogged or
damaged
Replaced tip
Fluid cured in pinch
tube
Replace with new tube
No Fluid Flow
The stroke adjustment

Fluid pressure
fluctuating
Make sure fluid pressure is
constant
Valve operating
pressure is too low
Increased valve pressure to 50
psi (3.4 bars)
Valve open time is not
consistent
Check to make sure the valve
controller is providing a
consistent output
Inconsistent
Fluid Flow
Air trapped in fluid line Purge valve
Decrease in fluid flow
Pinch tube lose its
flexibility
Replace with new tube
Fluid drools after the
valve closes,
eventually stopping
Air trapped in fluid line Purge valve
Steady drip
Pinch tube is not
installed properly
Re-install tube, follow

8. PINCH TUBE REPLACEMENT
CAUTION: Make sure the fluid pressure is released before disassemble the
valve.
Refer to figure 5.0
1. Release fluid pressure.
2. Disconnect fluid line.
3. Disconnect valve air line.
4. Remove the valve cap (1), the spring (6) and the shut off piston (5)
5. Lift the two ends of the tube (2) out of the grooves of the valve body (3).
6. Hold the pinch tube at the female luer lock fitting and pull it out of the valve
body.
7. Dispose the used pinch tube in an appropriate waste container.
8. Install a new pinch tube by inserting the male fitting of the tube through the
valve body.
9. Snapped the both ends of the pinch tube into the groove of the valve body.
10. Reinstall the shut off piston, the spring and the flange.
