StediFlo™ air control assembly
Installation Instructions
There are three control devices on the PowrTex Air Assembly (Part # 928-509), two conventional air regulators X and Z, and a surge
control StediFlo™ Valve W, which requires adjustment. Air regulator Z provides atomizing air, from the right hand outlet the StediFlo™
Valve W to the air motor. Air motor pressure usually ranges from 10-40 psi.
X (controls air
to air motor)
The 950-556 StediFlo™ is a surge control valve which disconnects the air pressure to the motor whenever the atomizing air flow to the
gun is stopped by releasing the spray gun trigger. The removal of the air pressure to the motor prevents further pressure build in the
fluid hose line and avoids a surge of high pressure material when the gun is opened.
The StediFlo™ Valve has an adjustment screw which will ensure that the spray gun and air motor will receive enough air pressure for
proper operation.
Set atomizing air regulator (Z) to desired atomizing level (i.e. 40 PSI). Adjust the knurled adjustment screw by turning it all the way
down (clockwise), open spray gun fluid valve and back off knurled adjustment screw until the valve stem of StediFlo™ valve is
approximately flush in the cover at point (Y), indicating the diaphragm has moved. Set motor air regulator (X) to lowest setting needed
to supply materials to the gun. Operation of the gun will actuate the air motor.
The 951-556 material valve is installed at the pump outlet. The instant the spray gun fluid valve is opened, the StediFlo™ valve
releases air to the motor and closes the material vent. When the spray gun trigger is released, the motor stops and the vent opens,
permitting the line pressure to discharge material back into the drum.
Coating materials vary widely in spray ability. See air data sheet for air cap and nozzle selection. Texture products will pump more
easily when particles are well-mixed and kept in suspension by agitation or other means.
After refilling the reservoir, the Automatic Lubricator will need adjusting. Turn the adjusting screw clockwise to increase the AirCare™
injection rate and counterclockwise to decrease it. Check the injection rate by observing the flow through the sight dome. The proper
flow rate is one (1) drop of AirCare™ per minute or every 90-125 cycles. In cold weather when icing may occur, increase to one (1)
drop every 50-60 cycles.
Operation at very high cycle rates (i.e. greater than 60) will require a higher AirCare™ injection rate.
IMPORTaNT: use only Titan aircare™ part # 311-101 lubricant. use of any detergent-type lubricants will cause a serious
problem with the pump and void the warranty.
Operation Instructions
The 950 StediFlo™ is a surge control valve which disconnects the air pressure to the motor whenever the atomizing air flow to the gun
is stopped by releasing the spray gun trigger. The removal of air pressure to the motor prevents further pressure build in the fluid hose
line and avoids a surge of high pressure material when the gun is opened.
The 951 Material Valve is installed at the pump outlet. The instant the spray gun trigger is depressed, the 950 Valve releases air to the
motor and if a 951 Material Valve is in the system, the material valve is closed. When the spray gun trigger is released, the motor stops
and the valve opens, permitting the line pressure to discharge material back into the drum
The 950 StediFlo™ Valve has an adjustment screw which will ensure that the spray gun and air motor will receive enough air pressure
for proper operation. When air is connected and the atomizing air regulator is adjusted to the atomizing pressure required (usually
40-80 PSI), adjust the 950-203 Adjustment Screw by turning it all the way down (clockwise), open spray gun and back off adjustment
screw until the stem of 950-218 is approximately flush to cover at point A, indicating the diaphragm has moved.
