Respective bearing plates with trunnion bearings are guide pin mounted between the respective tailpieces and in supporting engagement with respective trunnions on the ball control member for rotatably supporting the ball. A shaft bearing supports a valve shaft having a splined drive end engaging splines in one of the ball trunnions. Bidirectional fluid flow is enabled with ball sealing members on each ball side, with the sealing member on each side replaceable by removing the tailpiece on that side.
