Operation
Air Switch Hand Held Valve
The valve operation is such that there are only two
valve conditions: either fully open or fully closed.
The valve is opened and closed by the internal air
control valve. Trigger the gun to open the valve.
Release the trigger to close the valve.
Ratio Checking
The output mix ratio of your proportioner can be
checked by dispensing the two fluids separately out of
the nosepiece into tared cups. The cups can then be
weighed and the weights divided to get the mix ratio by
weight.
A divided outlet accessory (Part no. 626611) is avail-
able to make regular ratio checking easier. This
accessory fits the non-wide ratio valves and uses a
512292 retainer nut.
Ratio checks provide information on the ratio of an
overall sample. Transient problems (soft spots)
caused by starting and stopping the flow (lead-lag)
may not show up in this kind of ratio check. Physical
tests of the mixed fluid are the best check of correct
ratio and mix quality.
