With internal control:

Actuation of the 3/2-way control valve directs control air into the cylinder inside the 

gun so as to open - in sequence - the atomizing air and the material input. 

The shape of the spray is set on the gun with the models PILOT WA 900 / WA 920-

HVLP/ WA 940-HVLP

PLUS

/ WA 903-K and WA 923-HVLP-K using regulating screws 

(Pos. 28 and 29).

If the control air through the 3/2-way valve is interrupted, compressed air remaining 

in the cylinder chamber will first escape. The spring pressure of the piston spring 

subsequently pushes the material needle to its original position, closes the material 

supply and finally the spray air.

Without internal control:

The atomizer air (round and wide jet air) should first be switched on via an external 

3/2-way control valve provided by the customer. Then the control air is opened via a 

second 3/2 way valve, which presses both the piston and the material needle back 

in order to open the material supply.

For the models PILOT WA 905/ WA 925-HVLP/ WA 945-HVLP

PLUS

/ WA 908-K and 

WA 928-HVLP-K the shape of the spray jet is adjusted via the two customer supplied 

compressed air regulators in the plant.

If the control air is interrupted by the 3/2-way control valve, spring pressure will move 

the piston and the material needle back to their initial position and close the material 

supply to the material nozzle. The atomizer air should then be switched off.

The material flow volume is on all models set via the material pressure and the cap 

(item 26). The flow of material in the automatic spray gun series PILOT WA 900 can 

also be manually opened by means of the drawbar (Pos. 27).
The spray guns of the PILOT WA 900 series can be connected to material pressure 

tanks or pumping systems.
The models PILOT  WA  920-HVLP/  WA  925-HVLP/  WA  923-HVLP-K  and                            

WA 928-HVLP-K are pure low-pressure spray guns working with a spraying air   

pressure of 0.7 bar at an intake air pressure of 3,3 bar.
With the models PILOT WA 940-HVLP

PLUS

 bis WA 945-HVLP

PLUS

  the intake air    

pressure ranges from 3.0 to 3.3 bar for a spraying air pressure of 1.2 to 1.4 bar.

3.2 

Generally Applicable Safety Precautions

► 

All applicable accident prevention rules and regulations as well as other recognis-

ed industrial safety and health rules and regulations must be observed at all times.

 Use the spray gun only in well-ventilated rooms. Fire, naked flames and smoking 

are strictly prohibited within the working area. WARNING – during the spraying of 

flammable materials (e.g. lacquers, adhesives, cleaning agents, etc.), there is an 

increased risk to health as well as an increased risk of explosion and fire.

 You must ensure that the spray gun is properly earthed (grounded) either separa-

tely or in connection with the equipment with which it is being used (max. resistance 

10

6

 Ω).

 Before carrying out maintenance or servicing work, always ensure that the air and 

material feed to the spray gun have been de-pressurised. Risk of injury!

► 

When spraying materials, do not place your hands or other parts of the body in 

front of the pressurised nozzle or the spray gun. Risk of injury!

► 

Never point the spray gun at persons or animals. Risk of injury!

 Always observe the spraying and safety instructions given by the manufacturers 

of the spraying material and the cleaning agent. Aggressive and corrosive      

materials in particular can be harmful to health.

 Always wear hearing protection when using the gun or when in the vicinity of a 

gun that is in use. The noise level generated by the spray gun is approx. 86 dB(A).

 Exhaust air containing particles (overspray) must be kept away from the working 

area and personnel. In spite of these measures, always wear the regulation    

breathing masks and protective overalls when using the gun. Airborne particles 

represent a serious health hazard!

 After carrying out assembly or maintenance work, always ensure that all nuts, 

bolts and screw connections have been fully tightened before the gun is used.

 Use only original replacement parts, since WALTHER can only guarantee safe 

and fault-free operation for original parts.
