FREQUENTLY ASKED QUESTIONS
1) Does the valve need water or air pressure to
operate? Answer: No! One of the
advantages of motorized ball valves is that they can
function with minimal water pressure. This means a
motorized ball valve can work even with gravity fed
arrangements.
2) Will the ball inside the valve return to its original
position if the power goes out?
3) Can this valve be used outside? Answer: The
motorized ball valves are all rated IP67, which
indicates that they can endure temporary immersion
between 15cm and 1m. However, if installed
outdoors on a permanent basis, it is advised that you
encase the motorized ball valve in a protective
housing.
4) Can this motorized ball valve be powered
continuously? Answer: Due to the power limiting
features of these valves, they can be hooked up to
power non-stop without risk of overheating.
