Abstract
Multiport valve with outlets transverse to the inlet useful as a coker switch valve. A sealed lower sleeve assembly provides semi-trunnion ball support. An upper part of the outlet seat recesses is formed in the bonnet, and a lower part in the valve body, which together bias a resilient member to load the seats, independently of end connections. Before bonnet assembly, when the ball is rotated to face a body outlet, there is sufficient space in the seat recesses to insert the seat, slide the seat onto the ball, and then insert the resilient member. When all the seats and resilient members are in place, engagement of the bonnet biases the upper part of the resilient members to load the seat. In valve operation, an enlarged ball outlet bore can straddle two outlet ports and maintain process media flow during switching. Also, methods of assembling, operating, and servicing the valve.
