Abstract
Abstract The valve includes a body having aligned inlet and outlet ports intercommunicating by means of a central conduit passing through a rotatable ball mounted in the housing. The conduit permits fluid flow through the valve when the valve is in an open position and is alignable with the inlet and outlet ports. The rotatable ball is seated on sealing elements which are preloaded to provide sealing in both the open and closed valve positions.
