1. An electronic actuator couplable to a valve, the electronic actuator comprising:
a bracket, wherein the bracket comprises:
an electromagnet that extends in a first direction away from a body of the bracket;
a handle, wherein the handle comprises:
a connection portion pivotably couplable to the valve, wherein the handle is rotatable from a first position to a second position;
a stem extending from the connection portion, wherein the stem comprises:
a first end proximate the connection portion;
a second end opposing the first end;
a first side proximate the bracket;
a second side opposing the first side; and
a third side disposed between the first side and the second side;
an attractive component disposed on the second side between the second end and the connection portion; and wherein the attractive component couples with the electromagnet in of the bracket to inhibit closure of the valve when the electromagnet is magnetic; and
a second flange extending from the third side of the stem and disposed between the connection portion of the handle and the second end of the stem; and
a locking member coupled to the bracket; wherein the locking member comprises a spring-loaded latch capable of receiving at least a portion of the handle; and
wherein when the handle is disposed in the first position, the attractive component and the electromagnet are coupled and the valve is disposed in an open position;
wherein when the handle is disposed the second position, the portion of the handle is received in the spring-loaded latch and the valve is disposed in a closed position.
