It appears the SP0733 Dial-A-Flo is discontinued; other parts are available but I didn't see valve bodies. It looks like your valve is threaded?

You can use a Jandy valve like this one:
Jandy Space Saver 1-1/2 to 2-Inch Positive Seal Pool/Spa Valve, Gray
The valve can be oriented with any one of the ports as the discharge port. However it looks like you may need some 1.5" female thread adapters, plus a bit of 1.5" pipe, so you can connect the threaded ends of the hose clamped fittings.
