The Compact Expanding Gate Valve is a full opening non-thru-conduit mechanically sealing valve that achieves superior sealing by utilization of a two-piece parallel 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. Increases or decreases of line pressure will not affect the tight mechanical seal.
Available in line sizes 3" - 48", ANSI 150-300.
