Abstract
A reversible motor operated valve with a spring assist. The assist spring is provided to store energy therein as the motor actuates the valve from its closed to its open position. When the motor is reversed to actuate the valve back from its open to its closed position, the energy stored in the spring will be released to assist the motor in closing the valve.
