Hello I have a Barnes, PFG-30-10A3 Hyd. pump , and a vickers 3 pos. 4 way closed center valve. First does anyone know the flow rate and output pressure of this pump? and second What will I need in addition to make these power a double acting cylinder that needs to hold?

Without knowing the pump displacement and driver speed you can not know the pump flow delivery.
If the valve you have is a closed center valve you can not use it with the Barnes pump which is probably a fixed displacement pump. You need an open center cylinder valve which will bypass the pump flow and block the cylinder ports when the valve is centered.
I have not had good luck finding specs for your pump.

The pump number looks like a BSM Corp pump(Brown and Sharpe).
See this link:ht
I would guess your '30' size is halfway between the '20' and '40' size. Therefore displacement is 0.0018gal/cycle.
There is no indication of pressure capacity. BSM Corp. advertises pumps pressures 'up to 2000psi'.
