The Cameron selection of TBV valves includes the Series 21/18 two-piece, flanged, cryogenic ball valve, which offers unsurpassed reliability with a body machined from solid wrought materials, providing increased strength and virtually eliminating porosity. Materials include stainless steel, MONEL, titanium, and others as required. 

Using a split-body design, the body seal is totally encapsulated to prevent cold flow. Positive cavity venting into the upstream piping is accomplished by a relief hole in the ball. The leak-proof integrity of the valve is further enhanced by a welded bonnet design and V-ring packing, which can be adjusted by a simple turn of the stem nut.
