TS5540-MS Micro Spray Valve
User Guide
NOTE: The holes in the Needle Guide are evenly spaced, so there is no
specific rotation you must match. Just ensure the two pegs of the Installation
Tool fit into two holes in the Guide.
5. Using the Installation tool, fit the Needle
Guide into the Spray Cap (5) as shown.
Rotate the threaded guide clockwise
until it stops and remove the Installation
Tool.
6. Reinstall the Spray Cap and Locking Nut back onto the valve body.
7. Set valve air pressure at Valve Controller to 70 psi (4.8 bar).
8. Set the atomize air pressure at Valve Controller according to the
viscosity of fluid being spray.
9. Set fluid pressure at Fluid Reservoir according to the viscosity of fluid
being sprayed; do not exceed 100 psi (6.9 bars).
10. Place a waste bucket under the valve outlet and purge the valve until the
fluid flows steadily
Spray coverage is determined by:
•
Stroke control adjustment – Rotate Stroke Control Knob
clockwise to decrease flow rate and counterclockwise to
increase flow rate. DO NOT rotate the knob beyond the "Line
Marker" which is labeled on the knob shaft.
•
Length of actuation as set at Valve Controller (the
"valve-on" time)
•
Fluid reservoir pressure
•
Fluid viscosity
•
Distance between the needle/tip and the sprayed surface
•
Needle/tip size
