The setup with the diodes has two benefits. One, you can run just two wires from the spike to the valve and still operate both solenoids. Also, the diode setup prevents the possibility of activating both solenoids at the same time, with unpredictable results. However, most likely your valves won't be located far from the spike, so running three or four wires wouldn't be a problem; and activating both solenoids simultaneously can be avoided with careful programming.

Also, if you do connect the valve without the diodes, make sure you connect the correct leads to the relay. This depends on the type of spikes you have. If I recall correctly, you connect the red leads if you are using a blue spike, and the black leads if you are using a red spike.
