FLUID VALVE CONTROL

Trigger and Dump

(Refer to "Turbodisk Fluid and Air Pres-

sure Requirements")

The fluid valves in the Turbodisk are actuated by an air

signal. The air pressure must exceed 70 psi to assure

proper actuation of the valve. Applying air to the valve

actuator turns on the fluid flow for that valve.

The trigger valve controls the paint flow to the disk.

When actuated, paint flows through the valve to

the fluid tube. The disk should be spinning at a rpm

speed that is fast enough, (that when fluid is turned

on) to enable the fluid to flow through the disk paint

passage holes and be atomized.

The dump valve controls the paint flow through the

dump line. When actuated, paint flow is directed to the

dump return line. This provides a method of rapidly

removing paint from the incoming line for cleaning

and/or color change. Normally, the dump valve is not

actuated at the same time as the paint trigger valve

since the trigger valve is intended to cause the fluid

flow to the disk at the prescribed input pressure.

FLUID AND AIR PRESSURE RE-

QUIREMENTS

(Refer to "Turbodisk Fluid and Air Pres-

sure Requirements")

Fluid and air pressure requirements are dependent

on the fluid trigger valve configuration.

Note: Trigger/dump valves (CCV-403-SS) are rated to 300 psi maximum inlet fluid pressure but are limited

to the lower pressure limit of the fluid regulators.
