Abstract

Improvements introduced into ball valves comprising a valve body defining a valve core; a ball rotatably mounted on the valve bore to open and close the bore to the fluid flow; a seat that is applied to the ball; and a retainer, provided with a frusto-conical part, that keeps the seat in position, characterized in that the retainer (10) is provided with grooves (9) around the end of the frusto-conical part with a larger diameter so that it can be pushed into position through the valve bore (1) until the larger diameter end elastically springs out to engage a stop (12) provided in the valve bore, and has an elastic wing (7) for application to the seat extending outwards from the end of the frusto-conical part of smaller diameter, whereby when the retainer is inserted, the part (7) for application to the seat elastically deforms and applies a continuous load to the seat.
