The Model CBX control valve is designed specifically for cryogenic cold box applications. The unique design allows ready access to the seat ring after the body has been sealed in the cold box. A special seat extraction tool simplifies trim changing operations. Although the standard body extension is 14″, lengths up to 60″ are available on special order.
The use of a standard threaded bonnet allows the user a choice of bonnet styles, from TFE chevron ring packing to bellows seals. An optional casing flange or weldable sleeve facilitates field mounting.
