Apologies... In my original post I meant pins 1,3,4. And yes I have been able to rotate the motor CW and CCW with the pins and by applying voltage directly across the motor. However, I would like to use the pin wiring in my design to make use of the switches so I do not over rotate the valve. I have yet to test out the L293 yet, but the motor only pulls 1A so I was thinking it should be okay.
