Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a device and method for selectively cooling a high temperature area in a gas turbine.SOLUTION: A plug (30) for regulating a flow of gas (80) in a system (10) is disclosed. The plug (30) includes a housing (32) disposed on a temperature boundary (60) in a system (10). The housing (32) defines a passage (34) for flowing gas (80) therethrough. The plug (30) further includes at least one pressure-actuated valve (36) disposed in the passage (34) and movable between an open position and a closed position. The at least one pressure-actuated valve (36) moves from the open position to the closed position as the pressure of the gas (80) increases and moves from the closed position to the open position as the pressure of the gas (80) decreases.
