Flow Control Confusion
It has come to my attention that there is some confusion on flow controls on #1 Stop Air Stops (sometimes referred
to as "Bleed Valves"). The confusion is that you should set them to open in 1.00 second. This is not correct. You
need to open (and close) your Stop quicker than 1.00 second per inch of cylinder stroke.
Because #1 Stop air cylinders are 1" total stroke and you do not use all the stroke, you need to open quicker than
1 second. (Note: If you use .75" of stroke you need to open quicker than .75 second.) Normally, .4 to .5 second
opening is a great starting position. (Closing normally .1 to .2 is a good starting position) Remember, flow
controls are adjusted on the exhaust port of the cylinder. (Free flow in, control flow out.) If your Stop is
set-up opening (or closing) too slow, it can be inconsistent.
If you are set-up correctly on a single cylinder (2 air lines), stop, and are still spinning tires on the open,
try shifting on time (approx. 1.00 second is a good starting point). If you are still spinning the tires, consider
using a 3 Stage Stop and opening up in 2 stages. (Full stop, intermediate stop, and wide open)
You can close your stop as quickly as you can without getting a dip on your stop. Usually, you can close your stop
in .2 sec and have no dip. Open your stop in .6 sec and you will not spin your tires off the stop. Questions?
