2. UNPACKING AND INSPECTION
Carefully unpack the valve and examine the items contained in the carton.
These will include:
• Valve Assembly
• Sample Pinch tubes and Needle Kit
• User guide
• Valve Air Hose
Inspect the unit for any damaged which may have occurred in transit. If such
damage has occurred, notify the carrier at once.
Claim for damage must be made by the consignee to the carrier, and should be
reported to the manufacturer.
3. DESCRIPTION
The TS1212 valve is designed to dispense low to medium viscosity material
with precise deposits over a wide range of shot sizes. An internal spring return
makes the valve fully adaptable for use with Techcon Systems time/pressure
controllers. A short opening stroke provides extremely fast, positive shut-off.
An external stroke control adjustment makes it easy for the operator to fine
tune shot sizes.
4. THEORY OF OPERATION
The TS1212 is a normally closed, disposable pinch tube valve. Air pressures
through port (1) pushes the piston assembly (2) away from the seat (3) allowing
fluid to flow from the valve fluid inlet port (4) to the valve fluid outlet port (5).
Relieving the input air pressure allows the spring (6) to return the piston back
to its position to close the fluid path.

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.
