Abstract
A seal and seat for ball valves is a circular, elastomeric open torus which is fitted between the ball element and the housing. The open torus has within it, a substantially 'v' shaped spring that is fitted within the 'u' shaped opening of the torus. In normal operation, the spring member is slightly compressed between the ball and the housing and the ball can 'float' between a pair of substantially similar seals on the input and output sides of the ball valve, respectively.
