Narrative:

A BE9L was released by D10. After takeoff; one mile south of the airport; I saw a conflict developing with a VFR PA28 being vectored 3 miles south of afw at 2;500 ft northbound directly on the afw departure extended center line. I told the BE9L about the traffic and stopped his climb at 2;000 ft until PA28 was insight. The PA28 passed directly over the BE9L. If I had not stopped the climb; I believe we would have had a near mid-air or more likely a crash. Our standard climb out is runway heading and 3;000 ft. The MVA in that area is 2;100 ft. My concern is since I stopped the BE9L's climb at 2;000 ft is that an oe (operational error) because the minimum vectoring altitude is 2;100 ft. Recommend; D10 vector aircraft at 3;000 ft and restrict afw climb out to 2;500 ft.

Title: AFW Controller described a potential conflict event when an IFR departure was issued an altitude below the MVA to avoid VFR traffic being handled by D10; the reporter suggesting VFR should be issued a higher altitude by D10.
