Product Overview
This self-sealing wedge gate valve combines an integral forged body with a pressure-activated sealing system for demanding on-off isolation. The wedge travels vertically to open the passage or seat for shutoff.
The original page states stable sealing under high pressure and specifies self-sealing construction for Class 900 and above. Its bi-directional duty supports pipelines that require isolation in either flow direction.
Listed forged materials, NPT or socket-weld ends and manual or powered operation should be matched to the actual project conditions.
