Im new to hydraulics and am adding hydraulic power to my tubing bender.
I was able to land a (free!) motor and pump for the project. Ive seen a
lot of hydro powered benders so Ive got the idea down on how to build
the system. However, all the units Ive seen have a single stage pump
going into a 4 way valve to control the ram.

Can anyone point me in the right direction for the connection between
the two stage pump and the valve?

here is a pic of the pump:

Its a Webster part# 49912-47 if that matters.

thanks!
