API 6A and API 6D expanding gate valve combines the proven expanding gate design with close machining tolerances to provide a valve that seals under virtually all conditions The ZGV Through Conduit Expanding Gate is a full opening non-thru-conduit mechanically sealing valve that achieves superior sealing by utilization of a two-piece expanding gate. The mechanical sealing performance makes it ideal for critical double block and bleed applications. All valves meet the end to end and other requirements of API-6D or API 6A. Increases or decreases of line pressure will not affect the tight mechanical seal.
