Cryogenic and High Temperature Vales

Extended Body Cold Box Valve Assembly

Cryogenic & High Temperature Valves

Extended Body Cold Box Valve Assembly

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.

Cooling Fin Control Valves

Cooling Fin Control Valves

The Type 859 globe control valve with cooling fin bonnet is used in extreme temperature applications. It is designed for modulating flow control in industrial applications at 400…700° F at pressures less than 5000 psi (dependent on body and packing material). The added bonnet length and fins serve to reduce the heat at the packing area. This allows the standard CV ring packing to be used at higher process temperatures than could normally be tolerated with the standard valve.

The Type 973 globe control valve is designed for modulating flow control in industrial or research applications at 1000° F or less and at pressures less than 5000 psi. The added bonnet length and fins serve to reduce the heat at the packing area. The reduction in heat allows the standard CV ring packing to be used at higher process temperatures than could normally be tolerated with the standard valve.

Extension Bonnet Valve Assembly

The Type 884 extended bonnet globe control valve is available in varying lengths for 1/4" through 1" line sizes. It is specifically designed for control of extremely cold or hot fluids and gases. In cryogenic applications, the bonnet length serves to extend the packing area, as well as allow room for insulation around the body and bonnet. The design also facilitates cold box mounting. A casing flange is available as an option if sealing to the cold box is required. Other models are available to facilitate removal of the innervalve and seat from outside the cold box (Type CBX). In hot applications, the extended bonnet allows the standard TFE packing to be isolated from high temperatures. The factory should be consulted when service temperature exceeds 800° F (426° C).
