摘要： An engine shutoff valve is provided which includes a valve body having an air passageway in which a disc assembly and a valve seat assembly are located. The disc assembly includes a disc member which is arranged to be rotated and moved toward the valve seat assembly upon the occurrence of an engine runaway condition to close the valve. The valve seat assembly includes an anti-friction ring which is arranged to be engaged by the disc member when the valve is closed. The anti-friction ring is rotatable with respect to the valve body and the disc member to prevent the disc member from sticking thereto after closure of the valve, whereupon the valve can be readily reopened.
