ABSTRACT:
The specification and drawings disclose a ball valve designed to be highly reliable and easily maintained. The disclosed valve comprises an intermediate body section positioned between a pair of end fittings which are connected to the body by a plurality of longitudinally extending tie bolts. The tie bolts are arranged so that with removal of one, preferably color-coded or otherwise identified, the body can be pivoted outwardly from between the end fittings. The valve further includes seal assemblies axially removable from the ends of the intermediate body section and arranged to provide a seal between the end fittings and the body as well as between the body and an internally mounted valve ball. An improved stem seal and operating handle assembly for the valve are also provided in the valve.
