really I think the only advantage would be more plumbing options... other than that dont think there is any. I guess going direct to the bag would speed the dump up some if you are really wantin it to dump that fast.

i was told for fast fill and fast dump....but never really looked into it to verify that.....

i mean if ya think about it.....a single port bag ...to dump it has to travel back down the line to the valve....could also be for dual fill purposes...

dual port....you can put the valve by the bag and dump the shit outa it faster...

but im sure i might be wrong....and someone on here knows the real reason

i only ran single port slam bags on my old HB......

dual port is mainly for hoppers. to be use with compressed gas ie: nitrogen. to get the air in and out the fasest.

Putting the valve on a separate port doesn't make a big difference. You can still put the dump valve right on the bag with a single port, just have to know how to plumb it. The point is to run two valves, one to each port, and double the volume at which the air enters the bag. Personally I think its retarded, I try to slow down the bags by running small line, small valves, low pressure and reducers.

You can do that without dual ports. You simply hook all of the valves up to the same feed line. Then you run a 3 position toggle switch, with the center position hooked to a ground. One side of the toggle will ground the 1/2" valves, and the other side will ground your 1/4" valves. When one set of valves is grounded, the other set will not operate.
