How do you stop a relay from sticking?

Your relay contacts need a snubber and/or MOV/TVS to suppress the inductive spike when switching an AC inductive load (your valve). Without the suppression, the resulting arc can cause the contacts to “stick” (weld). If your load were DC, a diode across the coil would be the more common solution.

Why are relays needed?

Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal.
