Abstract
An improved seal for a rotary valve for high temperature and high pressure fluids. A removable seal member adapted for disposition between a valve body and a valve member rotatably disposed in the valve body is provided. In one aspect of the invention, the seal member is adapted so that pressure exerted by the valve is sufficient to induce cold flow in the seal member. In another aspect of the invention, the seal member includes a pair of longitudinally disposed slots.
