Abstract
A downhole distributor valve includes a housing that includes a housing fluid port therethrough, a mandrel that defines a bore and is positioned radially within the housing, and a fluid chamber radially defined between the housing and the mandrel and configured to contain a fluid at a particular pressure. The mandrel includes a mandrel fluid port therethrough. The mandrel is moveable from a first position with the bore fluidly decoupled from the housing fluid port to a second position with the bore fluidly coupled with the housing fluid port through the mandrel fluid port. The mandrel is moveable based on a hydrostatic pressure in the bore greater than the particular pressure of the pressurized fluid.
