Abstract
A downhole tool actuating arrangement includes, a control system configured to communicate pressurized fluid to at least one downhole tool actuatable by pressure changes in the control system, a check valve in operable communication with the control system configured to prevent fluid flow through the check valve in a direction opposite to flow that causes increases in pressure in the control system, and a bleed device. The bleed device is in operable communication with the control system downstream of the check valve, wherein downstream is defined by a direction of flow that causes the check valve to open. The bleed device is configured to allow fluid flow therethrough when pressure on the control system side of the bleed device is greater than on a side opposite the control system.
