3.3 Air Solenoid Valve
This section contains literature pertaining to the installation, operation and maintenance of the above
component.
As a built in safety feature, your
RTT
powder booth is provided with a two-way solenoid valve for the purpose
of
ensuring
that pressurized air is only available to the powder application equipment if the powder booth is
operating properly.
The function of this valve is to interrupt the supply of compressed air to the powder application equipment
under certain conditions. This is done to prevent powder coating from occurring when the powder booth is
not operating as designed or if any booth doors are open (if equipped). The air solenoid valve is electrically
interlocked with the powder booth exhaust fan(s). If the optional switches are purchased, it is also interlocked
with the product and personnel doors (if equipped). If the fan is not operating, or if a door (if equipped) is open
for longer than a few seconds, the air solenoid valve will shut off the flow of p
r
essurized air to the powder
application equipment.
The unit should be installed down stream of any regulators and filters and upstream of the powder application
equipment. It should be located as close as possible to the fitting to which the powder application equipment
connects in order to insure rapid loss of supply pressure.
