API 6D Expanding gate valve

Main features: Expanding gate valve is an efficient and reliable through-conduit gate valve, with two floating seats and parallel expanding gate and segment. The expansion action between gate and segment provides a tight mechanical seal on both upstream and downstream. Full bore through conduit design can eliminate flow turbulence. Pressure drop is no larger than through an equal length of pipe.
