Abstract

A pigging ball valve with a ball core mounted on an improved trunnion mounting. The pigging ball valve has a valve housing with a longitudinal axis. A side entry port on the valve housing is provided for entry of pigs into the valve housing. The ball core has an interior bore and is mounted on a trunnion in the valve housing for rotation about a transverse axis to the longitudinal axis of the ball core. The trunnion is a rotating stem journalled in the valve housing and connected to the ball core by a non-cylindrical portion and a cylindrical portion extending from the non-cylindrical portion towards the interior bore of the ball core. Preferably, the cylindrical portion terminates inwardly in a curved portion fitting the interior bore of the ball core.
