Beschreibung
Zusammenfassung:	A perimeter seated knife gate valve is described. Perimeter and transverse seals may be formed together as a single-piece or as two separate pieces. Wire-reinforced and with a rectangular cross section, the perimeter seal (portion) may fit into a corresponding groove in the single-piece body of the valve. Transverse seal (portion) may include two channels formed as side grooves or tubular channels to accept packing material, which energize the seal and are isolated from the fluid stream. In the two-piece version, a bottom groove of the transverse seal may be used to interlock both pieces. The shape and structure of the seal may allow single-piece valve body.
