Electrically-actuated ball valves for potable water meet NSF/ANSI 61 (National Sanitation Foundation/American National Standards Institute) requirements for handling drinking water. electrically-actuated valves use electric motors to open or close the valve and control media flow. Two-way brass electric ball valves for potable water have one inlet and outlet port. Brass is a malleable, corrosion-resistant copper and zinc alloy that is unlikely to crack.
