Roetelmann Multi-Way Ball Valves

In multi-way ball valves with a trunnion ball the sealing and the bearing function are separated from each other. The trunnion ball has two trunnions that are guided in plastic bearings. The seats are forced against the trunnion ball by o-rings and are pressure equalized. The seats are pushed into the ball and not the ball into the seat.
