The Series 746 bidirectional knife gate valve features a one piece urethane liner molded throughout the body and chest providing Class VI shutoff in the most abrasive applications. The liner extends over the front face of the body, ensuring total protection from abrasive media and eliminating the need for additional gaskets. The one piece, durable ductile iron body is offered in a compact wafer style for ease of handling and installation.
