Where to find a catalog of valves

Hey guys, I have been asked to do some 3-D drawings in Solidworks of our product that we produce. We make the vaults and pump stations that house the pumps and valves to move fluid though. We are in the process of making a new catalog showing how the valves and piping fit in out tanks. Was wondering if there is a website someone could point me to that might have these valves and piping for download. At this time I just need something generic. Looking for something similar to what in autocad would be considered a "block".

Thanks for the help.
