Abstract

A flow control valve includes a valve seat, a valve plug movable relatively to the valve seat between a valve open position and a valve closed position, and a seal member interposed between the valve seat and the valve plug. The seal member includes a base portion attached to one of the valve seat and the valve plug, and a seal lip having a circular truncated cone shape and protruding obliquely inward in the axial direction from a surface of the base portion. The seal lip separates from or elastically contacts the other of the valve seat and the valve plug depending on the position of the valve plug. The base portion has a circular recess extending continuously in a circumferential direction and having an inner surface continuous with an inner circumferential surface of the seal lip.
