Series 3-6-12 Steering Control Unit, Non-Load Reaction, 7.30 cu in/rev, 4-8 GPM Flow Range, 3/4-16 St.Thd O-Ring Ports, Can be used in a variety of applications|Flow rate variability|Varying maximum pressure ratings

For port and displacement specs, yes, that lines up. The unit runs 7.30 cubic inches per revolution and uses 3/4-16 straight thread O-ring ports. Mounting is handled by a 4x .375-16 UNC-2B pattern on the mounting face, with 2x .375-24 UNF-2B on the port face. The mechanical interface is an internal involute spline, 12 tooth, 16/32 DP, 30 degree pressure angle, so you'll want to confirm your shaft matches that before ordering.

For flow, it’s set up for a 4 to 8 GPM range and the displacement is 7.30 cu in per revolution, so it matches that kind of steering circuit without needing to be pushed outside its stated flow window.
