If you have rebuilt the pump and the ram, you certainly have the skills and ability to rebuild the control valve. Have you removed the valve from the linkage yet? There is a roll pin inserted into the linkage that keeps the valve from spinning that must be removed. Be careful and gentle removing the brass liner inside, it is easy to booger that up. Note that when you torque the nut on the end of the control valve, you torque in INCH/pounds, not foot/pounds. Finally, make sure you have the two short hoses connected to the correct ports on the valve or the steering wheel will literally kick like a mule when you start the car.
