12. LIMITED WARRANTY

Manufacturer warrants this product to the original purchaser for a period of one (1)

year from date of purchase to be free from defects in material and workmanship,

but not against damages by misuse, negligence, accident, faulty installations and

instructions. Manufacturer will repair or replace (at factory’s option), free of

charge, any component of the equipment thus found to be defective, on return of

the component, “PREPAID” to the factory during the warranty period. In no event

shall any liability or obligation of the Manufacturer arising from this warranty

exceed the purchase price of the equipment. This warranty is only valid if the

defective product is returned as a complete assembly without physical damage.

The Manufacturer’s liability, as stated herein, cannot be altered or enlarged except

by a written statement signed by an officer of the company. In no event shall the

Manufacturer be liable for consequential or incidental damages. A return

authorization is required from Techcon Systems prior to shipping a defective unit

to the factory.

Manufacturer reserves the right to make engineering product modifications

without notice.

All returns must be issued with a Returns Authorization number, prior to return.

2. UNPACKING AND INSPECTION

Carefully unpack the valve and examine the items contained in the carton. These

will include:

• Valve Assembly

• Valve bracket

• User guide

• Valve Air Hose

3. DESCRIPTION

The TS5520 Series Spray Valve is designed to spray low viscosity fluid with very

precise deposits. An external stroke control makes it easy for the operator to fine-

tune fluid flow. Total control of the spray cycle is provided by adjustable fluid

flow and precise control of pre-spray, atomizing air and post-spray with

theTS500Rspray valve controller. Maintenance is made simple by the elimination

of troublesome spring loaded needle packings. The valve’s compact design and

easy mounting hole allow for easy integration into automated applications.

4. THEORY OF OPERATION

The TS5520 Series Spray Valve is a normally closed, adjustable opening, needle

and seat valve. Inlet air pressure through port (2) retracts the needle assembly (7)

from the seat (4) allowing fluid to flow from the valve fluid inlet (6) to the outlet

nozzle (5). Air pressure through port (3) passes around the dispense “orifice”

providing the atomized spray pattern. Relieving the input air pressure allows the

spring (1) to return the needle back to its position to close the material path.
