Abstract

PURPOSE:To ensure the smooth rotational manipulation of a valve element by providing a seal ring having its outer end part with tapered inner and outer peripheral surfaces, and by forming the seal ring in such a tapered shape that the cross angle between the virtual prolonged surfaces of the inner and outer peripheral surfaces becomes acute. CONSTITUTION:The forward end part of a seal ring 11 for sealing the outer peripheral surface of a valve element 6, has tapered inner and outer surfaces 11e, 11f, having a tapered shapes so that the cross angle alpha between the virtual prolonged surfaces 13, 14 of the inner and outer peripheral surfaces 11e, 11f becomes acute. Further, the forward end face of the seal ring 11 is coated with fluororesin. With this arrangement the area of the forward end part of the seal ring 11 abutting against the outer peripheral surface of the valve element 6 may be reduced, and may have a low wear resistance, thereby it is possible to smoothly rotate the valve element 6.
