ELECTRICALLY OPERATED VALVE AND METHOD THEREOF
First Claim
1. A downhole tool assembly comprising:
- a tubular having a flowbore extending along a longitudinal axis of the tubular;
an electric actuating mechanism supported by the tubular and distanced from the longitudinal axis of the tubular; and
,a valve assembly connected to the tubular and fluidically connected to the flowbore, the valve assembly including;
an outer portion having at least one port; and
an electrically actuated inner portion concentrically positioned within the outer portion and operable by the actuating mechanism to selectively block the at least one port in a first condition of the valve assembly and unblock the at least one port in a second condition of the valve assembly.

Abstract
A downhole tool assembly includes a tubular having a flowbore extending along a longitudinal axis of the tubular. An electric actuating mechanism supported by the tubular and distanced from the longitudinal axis of the tubular; and, a valve assembly connected to the tubular and fluidically connected to the flowbore. The valve assembly including: an outer portion having at least one port; and an electrically actuated inner portion concentrically positioned within the outer portion and operable by the actuating mechanism to selectively block the at least one port in a first condition of the valve assembly and unblock the at least one port in a second condition of the valve assembly. A method of actuating a valve assembly in a downhole tubular.

16. A method of actuating a valve assembly in a downhole tubular, the method comprising:
-
inserting a tubular having a flowbore into a borehole; employing a peripherally positioned electric motor within the tubular; actuating an electrically activated valve assembly with the motor, the valve assembly including an outer portion having at least one port and an inner portion movably configured within the outer portion; and
,selectively moving the inner portion to block the at least one port in a first condition of the valve assembly and selectively moving the inner portion to expose the at least one port in a second condition of the valve assembly; wherein fluid flow through the tubular during both the first and second conditions of the valve assembly is not blocked. - View Dependent Claims (17, 18, 19, 20)
