2 Wire Auto Return

Motorized ball valves with the two wire auto return function can be vital in some applications. They are often used as a backup shutoff valve for water systems. When power is removed, the valve automatically closes. This does mean the valve uses nominal energy even when fully actuated, as it has to be able to close at power shutoff. These valves can be connected to a simple on/off switch for a hassle-free setup and start.
