Just got a pair, thanks BC gang! 2 questions since they came without documentation or instructions and I could not find them on the BC site: 1. One of the outlets is marked with a dimple; is that in or out? 2. What are the safe operating voltages for the 6V version? Thanks for the candy!
Of the two ports on a typical solenoid valve, the outlet port will be the one that is deeper (reaches the center of the valve body).
