Twin Plug is a DB&B valve with both the plugs having the same orientation. This design is typically used on manifolds where a large number of valves are placed next to each other with one of the plugs actuated and the other plug gear operated or both the plugs gear operated. This design gives the overall smallest dimension. Twin Plug is produced in sizes up to 36" in pressure class 150# - 2500#.
