摘要: A dual lock flow gate includes a valve with a flapper which may be fixed and/or locked in various positions for example to prevent fluid flow in the production string during lowering of the production string in the casing by blocking flow in the production string with the dual lock flow gate or for example to prevent rotation of the pump motor by preventing fluid flow in the production string.
