Along with all of the features and versatility of a three-piece valve, Cameron's TBV Series 1100 valve incorporates a raised face on the seat-bearing side of the endplate which ensures positive alignment of the components and eliminates radial piping stresses. The body seal is 100% encapsulated to eliminate cold flow of virgin PTFE body seals. Rugged construction features a heavy-duty handle and stop plate with a variety of bolting material options. Available in a wide variety of materials with NPT, socket-weld and butt-weld end connections.
