Bending phenomenon automatically corrects the following gaps to prevent fluid leakage, and in case of slight fluid leakage between metal sheets, multi-stage pressure reduction between sheet contact surfaces The present invention relates to a seating device for a valve, which minimizes the amount of leakage and prevents leakage regardless of the direction of fluid pressure upstream of the valve. In the valve for controlling the flow of fluid, several sheet protrusions formed on the sheet surface formed on the inner peripheral surface of the valve body The sheet sheet 300 is strongly pushed by the sheet, and a slight leakage of the sheet is caused by the sheet member 300 which minimizes the leakage of the fluid by the multi-stage reducing action of the sheet lifter and the decompression groove, and the tightening force wound around the inner circumference of the sheet member. And an elastic tension bar (500, 510) to tighten the inner surface of the sheet member to maintain close contact with the mating sheet.
