Normal Use

The automatic spray guns of the WA XV type series are exclusively designed for use
with sprayable material types and grades. All wetted parts are made of stainless
speciality steel so as to permit handling of hydrous and/or aggressive media such as,
for example:
• paints and lacquers
• greases, oils and corrosion preventives
• adhesive compounds
• ceramic glazes
• pickling solutions
If your specific material is not listed above, please contact us for further and detailed
information.
Please note that sprayable material may only be applied to workpieces and/or similar
items.
The temperature of the spraying material shall never exceed 80 degs. C.
The WA XV needle-pull gun is not designed for manual operation, but must be
installed in a suitable gun mounting device.
The term normal use also implies that any and all safety warnings, operational hand-
ling details, etc., as contained in these Operating Instructions, are carefully read,
understood and duly complied with.
This equipment complies with the explosion protection requirements of Directive
94 / 9 / EC (ATEX) for the explosion group, equipment category and temperature
class indicated on the type plate. When using the equipment, the requirements spe-
cified in these Operating Instructions must be observed at all times.
The technical data indicated on the equipment rating plates and the specifications in
the chapter "Technical Data" must be complied with at all times and must not be
exceeded. An overloading of the equipment must be ruled out.
The equipment may be used in potentially explosive atmospheres only with the
authorisation of the relevant supervisory authority.

The relevant supervisory authority or the operator of the equipment are
responsible for determining the explosion hazard (zone classification).
The operator must check and ensure that all technical data and the marking of the
equipment in accordance with ATEX are compliant with the necessary requirements.
The operator must provide corresponding safety measures for all applications in
which the breakdown of the equipment might lead to danger to persons.
If any irregularities are observed while the equipment is in operation, the equipment
must be put out of operation immediately and WALTHER Spritz- und Lackier-
systeme must be consulted.
Grounding / Equipotential Bonding
You must ensure that the spray gun is properly earthed (grounded) either separately
or in connection with the equipment with which it is being used
(maximum resistance 10 Ω).

Technical Description

Spray guns of the WALTHER PILOT Type Series WA XV are allautomatic air-con-
trolled guns operating in combination with a 3/2-way control valve in the form of
hand-, foot- or solenoid-actuated valves.
Actuation of the 3/2-way valve directs control air into the cylinder inside the gun so
as to open - in sequence - the atomizing air and the material input.
Closing of the 3/2-way valve is followed by the control air escaping from the cylinder
inside the gun, upon which the spring-loaded material control needle returns to its
initial position, where it shuts the material and atomizing air Input off.
The material flow rate and the spray jet contour (i.e. flat, wide or round) are adjusted
at the gun by way of regulating screws.
The material inlet duct of the WA XV needle-pull can be opened by hand so as to
permit, for example, cleaning of a clogged material nozzle.
The model PILOT WA XV-HVLP is a low pressure spray gun and operate with a
spraying pressure of 0.7 bar using an inlet pressure of 3.5 bar.
The gun front attachment with twin connector for material input permits inclusion of
the PILOT spray gun in a circulation system the closed loop layout of which is desi-
gned to operate several spray guns.
This spray gun can be connected to material pressure tanks, pumping and circulati-
on systems.
