Yes, barrel valve is the same, spool is different.  Something in your system isn't doing what it is supposed to.  You should be feeding the pump with a #12 or bigger line, #8 from pump to 3-way shutoff, #8 to the barrel valve.  Now, between the shutoff and barrel valve should be a tee with your main by-pass, unless it is built into the barrel valve (like an Enderle unit).  An Idle by-pass is a good thing, and it should be set to open at 18 - 20 psi.  If there isn't any blockages anywhere in your system, with a #50 main pill, you should be pig fat.  Check every line, distribution block, and fitting for an obstruction, and make sure that when you thing your shutoff is open, it really is!

You dont need all that Idle bypass spring pressure, its only open when the BF's are closed and with that pump there is not enough pressure to open it
